Property Developer Changes the Project After the Sale in Turkey: Rights of Foreign Buyers – 2026 Legal Guide

What can a foreign buyer do when a Turkish property developer changes the project after the sale? Learn about apartment layout changes, missing facilities, smaller units, project modifications, contract cancellation, refunds, price reduction and compensation claims in 2026.

A foreign buyer may purchase an off-plan apartment, villa or investment property in Turkey based on architectural plans, brochures, computer-generated images, technical specifications and detailed promises concerning how the completed development will look. Months later, the developer may announce that the project has changed. The swimming pool may disappear, landscaped areas may become additional buildings, the apartment layout may change, the unit may become smaller, parking may be reduced, a promised private garden may become a common area or another building may be constructed directly in front of an apartment sold for its view. This raises an important legal question: Can a property developer in Turkey unilaterally change a project after the foreign buyer has signed the contract and paid the purchase price? The answer depends on the type and significance of the modification, the contractual documentation, whether the transaction falls within the prepaid housing framework, what the buyer was originally promised, whether the change is legally or technically necessary, and whether the buyer validly consented to the modification. A contractual clause allowing certain technical adjustments does not necessarily give the developer unlimited power to deliver a fundamentally different investment.

Why Project Changes Are Especially Dangerous for Foreign Buyers

Foreign investors frequently buy Turkish property before construction is completed. The buyer is therefore purchasing not only existing bricks and concrete but a future contractual promise. The decision may be based on the apartment’s floor, view, orientation, size, terrace, garden, parking, swimming pool, gym, landscaping and surrounding buildings. If those features change during construction, the economic value of the investment may change substantially even though the developer technically delivers an apartment.

Can a Developer Change an Off-Plan Project After Sale?

Some modifications may be possible, particularly where they are technically necessary, legally required or permitted within the applicable contractual and regulatory framework. However, the developer should not assume that every modification can be imposed unilaterally simply because construction is ongoing. The central issue is whether the change is minor and technically reasonable or material enough to alter the property the buyer agreed to purchase.

Minor Technical Change vs Material Project Change

This distinction is critical. Replacing a construction material with a genuinely equivalent product because the original is unavailable may be very different from removing a promised swimming pool. Slightly relocating technical equipment may differ from moving the buyer’s apartment to another building. A minor engineering adjustment may differ from reducing the apartment’s promised area by 20%. The greater the effect on use, market value, rental value, privacy or investment purpose, the stronger the buyer’s potential objection.

1. Apartment Becomes Smaller Than Promised

A foreign buyer may sign for a 160 m² apartment but discover during construction that the completed unit will be materially smaller. The first question is whether the contractual figure represents net area, gross area or another measurement methodology. The original contract, floor plan, technical specification and final measurements should be compared. A substantial reduction in promised area can potentially support claims involving correction, price adjustment, compensation or stronger remedies depending on the circumstances.

2. Apartment Layout Is Changed

The buyer may have selected a property because it contained three bedrooms, two bathrooms, an open-plan kitchen and a large terrace. The developer later modifies the floor plan and removes one bathroom or significantly reduces the living room. Even if the total area remains similar, the functionality and market value can change. The legal significance depends on whether the original layout formed part of the contractual specifications and the extent of the alteration.

3. Developer Changes the Buyer’s Apartment

A particularly serious dispute arises where the developer attempts to substitute another independent unit. The buyer purchased Block A, Unit 25, 12th Floor, but the developer proposes Block C, Unit 14, 7th Floor. The developer should not assume that two apartments of similar size are legally or economically interchangeable. Floor, orientation, view and location within the project may produce major differences in value.

4. Floor Is Changed

High-floor apartments often command substantial premiums. A foreign investor who paid EUR 500,000 for a 15th-floor unit may not accept a 7th-floor unit merely because the internal area is similar. If the specific floor formed part of the agreed property description, a unilateral substitution can create a serious contractual dispute.

5. Orientation Is Changed

A south-facing apartment can differ materially from a north-facing apartment in terms of sunlight, temperature, view and marketability. Where orientation was specifically identified in plans or contractual documents, changing it may affect the economic substance of the purchase.

6. Promised Sea View Is Lost

One of the most valuable characteristics of coastal property is the view. A developer may sell an apartment using the phrase “permanent panoramic sea view” and later modify the project by adding another building directly in front of it. The buyer should compare the original site plan, later revisions and marketing representations. If the view was a material part of the sale and price, loss of that feature can become a significant compensation issue.

7. New Building Is Added in Front of the Apartment

A buyer may select a property because the original project plan shows an open landscaped area in front of the building. After sales are completed, the developer adds another residential block. This may reduce view, privacy, sunlight and market value. The buyer should determine whether the original site plan was contractually binding, whether the developer reserved modification rights and whether the new construction was legally approved.

8. Swimming Pool Is Removed

Suppose a resort project was sold with a large outdoor pool as a central feature. Foreign investors paid premium prices partly because of that facility. The developer later eliminates the pool and replaces it with additional construction. If the swimming pool formed part of the agreed project rather than merely an illustrative concept, buyers may have significant contractual claims.

9. Swimming Pool Becomes Much Smaller

Developers sometimes argue that they technically delivered the promised facility. The brochure showed a large resort-style pool, while the completed development contains a dramatically smaller pool. The dispute then concerns not complete non-delivery but whether the facility materially conforms to the contractual representation.

10. Gym, Spa or Social Facilities Are Removed

Foreign buyers often purchase investment apartments in developments marketed around extensive facilities. These may include a gym, spa, sauna, children’s area, cinema, meeting rooms or residents’ lounge. Removing significant facilities can affect both resale and rental value. The contract and technical specification should establish whether these facilities were actually promised.

11. Landscaped Garden Becomes Additional Construction

A development may originally be marketed with extensive green areas. Later, the developer adds commercial units, another residential block or parking structures. Buyers who paid a premium for low-density development may face a fundamentally different project. The original and revised plans should be compared carefully.

12. Private Garden Becomes Common Area

A ground-floor apartment may be sold with a “private 150 m² garden.” After construction, the buyer discovers that the garden is legally part of the common area or available only through a limited use arrangement. The distinction between ownership, exclusive use and common property is legally significant and should be examined through the relevant project and condominium documentation.

13. Private Terrace Is Reduced or Removed

Penthouse apartments often command high prices because of large terraces. A foreign buyer may discover that the final terrace is substantially smaller than the one shown in the signed plan. If the terrace materially influenced the price, the difference may support an economic claim.

14. Parking Arrangement Changes

The original sales package may promise two private parking spaces, while the final project provides only shared parking. Alternatively, underground parking may be replaced with outdoor spaces. These arrangements are not necessarily economically equivalent. The contractual description of parking rights should be reviewed.

15. Storage Area Is Removed

A buyer may have purchased an apartment together with a storage room. During construction, the developer redesigns the basement and eliminates storage units. Even where the apartment itself remains unchanged, failure to provide an agreed accessory can constitute non-conforming performance.

16. Building Entrance and Common Areas Are Downgraded

Luxury projects are often sold through images showing large lobbies, concierge areas and high-quality common spaces. If these are materially downgraded, buyers may argue that the final development differs from the promised investment. General promotional language can be difficult to enforce, but detailed technical specifications and architectural plans provide stronger evidence.

17. Construction Materials Are Changed

The contract may specify natural stone, particular flooring, branded appliances, high-performance windows or specific heating and cooling systems. The developer later substitutes cheaper alternatives. The legal issue becomes whether the replacement is genuinely equivalent or materially inferior.

18. Smart Home System Is Removed

Modern projects frequently advertise integrated smart-home technology. If the system formed part of the technical specification and is not delivered, the buyer may potentially demand performance, appropriate price adjustment or compensation depending on the circumstances.

19. Heating or Cooling System Changes

A property marketed with underfloor heating or central air conditioning may be delivered with a substantially different system. These changes can affect both comfort and operating costs. The buyer should compare the technical specification with the completed property.

20. Developer Changes the Building Exterior

Changes to facade design, balcony structure, window dimensions or architectural appearance can alter the character and value of a premium project. Whether such modifications create legal remedies depends on their significance and the contractual documentation.

21. Number of Apartments Increases

Suppose a project was marketed as an exclusive development containing 100 apartments. The developer later redesigns it to contain 180 units. This can affect common-area usage, parking, privacy, facility capacity and investment value. Buyers should examine whether the density and number of units were part of the contractual project description.

22. Commercial Units Are Added

A quiet residential project may later include restaurants, shops or other commercial spaces. Depending on their nature and location, these can affect noise, traffic, privacy and the character of the development. The original project documentation should be compared with the revised plan.

23. Access Road or Main Entrance Changes

Changing the project’s main entrance or access road can affect convenience and value, particularly in large developments. A buyer may have selected a particular building because it was close to the entrance, while the revised layout places it much farther away.

24. Beach or Waterfront Access Changes

Resort projects may be sold with direct or exclusive beach access. If later project modifications remove or materially restrict that access, buyers should investigate whether the original representation constituted a contractual feature.

25. Developer Says the Images Were “Only Illustrative”

This is one of the most common defenses in off-plan disputes. Many brochures contain disclaimers stating that architectural images are illustrative and may change. Such language can be relevant, but it should not automatically be assumed to authorize every modification. A general illustration disclaimer is different from an express contractual right to replace the buyer’s unit, remove major facilities or materially reduce apartment size.

26. Developer Says the Contract Allows Any Changes

Off-plan contracts sometimes contain broad clauses allowing the developer to make modifications required by technical, administrative or architectural reasons. The exact wording should be examined carefully. A clause designed to permit necessary technical adjustments should not automatically be interpreted as unlimited permission to change the fundamental economic characteristics of the property.

27. Is the Buyer Required to Accept Every Contractual Modification Clause?

Not necessarily. The validity, interpretation and scope of broad unilateral modification clauses may need to be examined under applicable contract and consumer-law principles. The fact that a clause appears in a standard-form agreement does not mean that every exercise of that clause is automatically lawful.

28. Prepaid Housing Rules Can Be Particularly Important

Foreign individuals purchasing residential property from a developer before delivery may, depending on the circumstances and purpose of acquisition, fall within Turkey’s consumer and prepaid housing framework. These rules can impose important requirements concerning preliminary information, contract content, project details, delivery and changes affecting the transaction. Whether the buyer legally qualifies as a consumer must be determined case by case, particularly where multiple properties are purchased for commercial investment.

29. Consumer Status of Foreign Buyers

Foreign nationality does not by itself prevent a person from benefiting from Turkish consumer protection rules. The more important question is the nature and purpose of the transaction. An individual buying a home for personal use can stand in a different legal position from a company acquiring dozens of apartments as part of a commercial investment business.

30. What Happens When the Project Is Materially Changed?

Where a legally significant project change occurs, the buyer’s available rights depend on the transaction and applicable rules. Potential remedies can include objecting to the change, demanding contractual performance, seeking correction, requesting an appropriate price reduction, claiming compensation, exercising statutory rights available in qualifying prepaid housing transactions or seeking termination where the legal requirements are satisfied.

31. Can the Foreign Buyer Cancel the Contract?

Potentially. A sufficiently serious change may justify ending the contractual relationship depending on the applicable statutory and contractual framework. However, cancellation should not be attempted casually. The buyer should determine the legal basis, notification requirements, timing and financial consequences before sending a termination notice.

32. Can the Buyer Demand the Original Apartment?

Potentially, where delivery of the specifically agreed unit remains legally and physically possible. The buyer’s contract should be reviewed to determine whether a particular independent unit was clearly identified and whether the developer reserved any lawful substitution mechanism.

33. Can the Buyer Keep the Property and Claim a Price Reduction?

Potentially. This may be commercially preferable where the buyer still wants the apartment but the modifications have reduced its value. Expert valuation can compare the market value of the property as promised with the market value as actually delivered.

34. Can the Buyer Claim Compensation?

Potentially, where breach and recoverable loss can be established. Compensation may involve direct economic consequences caused by the modification. A buyer claiming damages should document the relationship between the promised feature, the change and the resulting financial loss.

35. Lost Rental Value

Project changes can significantly affect rental income. An apartment marketed as a premium resort investment with pool, spa and private beach access may command less rent if those facilities disappear. A compensation claim based on rental loss requires reliable evidence rather than speculative projections.

36. Loss of Resale Value

A project modification can also reduce resale value. A sea-view apartment blocked by a newly added building may sell for significantly less than the originally promised property. Independent valuation evidence can become particularly important.

37. Can the Buyer Recover the Purchase Price?

Where the contract is validly terminated or otherwise unwound under the applicable legal framework, recovery of amounts already paid may become the primary claim. The buyer should preserve every payment record, including bank transfers, SWIFT records, receipts, payment schedules and foreign currency documentation.

38. Do Not Sign a New Project Plan Without Legal Review

Developers sometimes ask buyers to sign revised plans or amendments after construction changes. A buyer who signs may later face an argument that the modification was expressly accepted. Foreign buyers should therefore obtain independent advice before signing any document described as:

Revision

Technical Amendment

Updated Floor Plan

Project Confirmation

Delivery Amendment

or

Supplementary Protocol.

39. Silence Can Create Evidentiary Problems

If the developer formally notifies the buyer of a major modification and the buyer remains silent for a long period while continuing performance, later disputes may become more complicated. Buyers should document objections promptly rather than relying solely on telephone complaints.

40. WhatsApp Messages Should Be Preserved

A developer representative may say:

“Do not worry. The swimming pool will definitely remain.”

or:

“The new building will not block your view.”

These messages can become important evidence if the final project contradicts those representations. Preserve complete conversations and original files.

41. Preserve the Original Brochure

The original brochure may disappear from the developer’s website after the project changes. Foreign buyers should preserve PDF brochures, screenshots, videos, advertisements, floor plans, price lists and promotional emails from the date of purchase.

42. Compare the Original and Revised Site Plans

One of the most effective forms of evidence is a side-by-side comparison:

Original Project Plan → Revised Project Plan → Completed Development.

This can reveal added buildings, removed facilities, changed landscaping, altered roads and changes in apartment positioning.

43. Independent Technical Expert Review

Architects, engineers and valuation experts may be needed to determine whether the final development materially differs from what was promised. Legal analysis and technical evidence often need to work together.

44. Delivery Form Can Be Dangerous

At handover, the developer may ask the buyer to sign a document stating that the property was received “fully, completely and without defect.” If significant project changes exist, signing such a statement without reservation can create unnecessary evidentiary difficulties. Known objections should be documented appropriately.

45. Developer Offers a Small Discount

A developer may acknowledge the change and offer a small refund. Before accepting, the buyer should determine the actual economic loss. A EUR 10,000 discount may be inadequate if the removal of a sea view reduces the apartment’s market value by EUR 100,000.

46. Be Careful With “Full and Final Settlement”

Settlement documents may contain broad language waiving all present and future claims. Foreign buyers should not sign such documents before calculating the value of the project changes and understanding exactly which rights are being released.

47. Developer Financial Problems

Project changes sometimes occur because the developer is trying to reduce construction costs due to financial distress. If facilities are repeatedly removed, materials downgraded and completion delayed, the buyer should investigate whether the developer has broader solvency problems.

48. Mortgages and Attachments Should Also Be Rechecked

A major project revision can be a warning sign. Buyers should consider updating title due diligence to determine whether mortgages, attachments or other restrictions have appeared since the original contract was signed.

49. Interim Protection May Become Necessary

Where the dispute concerns a specific property or the developer’s actions could make the buyer’s eventual claim ineffective, appropriate interim judicial protection may need to be evaluated. The exact measure depends on the substantive claim and statutory requirements.

50. Monetary Claims and Developer Assets

If the buyer seeks a refund or substantial compensation, developer solvency becomes critical. Winning EUR 500,000 against an insolvent company is different from actually recovering EUR 500,000. Where legally available, asset-preservation strategies should be considered early.

Practical Example: Sea View Blocked by New Building

Foreign buyer purchases a 12th-floor apartment for EUR 600,000 based on the original project showing landscaped gardens between the apartment and the sea. After the sale, the developer adds another residential block directly in front. The buyer should preserve the original site plan and advertising, obtain the revised project documentation and commission an assessment of the effect on value.

Practical Example: Swimming Pool Removed

Buyer purchases an investment apartment in a resort project specifically marketed with a large swimming pool. Developer later removes the pool and builds additional apartments in the same space. The legal analysis should determine whether the pool formed part of the agreed project and whether the modification materially affects the property’s value and use.

Practical Example: Apartment Reduced in Size

Contract and plans identify a 140 m² net apartment. The completed unit is materially smaller. The buyer should obtain independent technical measurement, compare the approved and contractual plans and quantify the value difference before selecting a remedy.

Practical Example: Two Parking Spaces Become Shared Parking

Foreign buyer pays a premium because the contract includes two allocated parking spaces. Final development provides only general shared parking. The buyer may consider performance, price reduction or compensation depending on the contractual structure and legal status of the promised parking rights.

Practical Example: Private Garden Becomes Common Area

Ground-floor villa-style apartment is marketed with a 250 m² private garden. After completion, the buyer learns that the area is legally common property. This may materially affect value and should be analyzed through the contract, condominium documents and original marketing representations.

Practical Example: Developer Changes Apartment Without Consent

Foreign investor purchases Unit A-45 because of its floor and orientation. Developer later offers Unit C-21 and says it is “equivalent.” The buyer should not accept equivalence without independent valuation and contractual analysis.

2026 Action Plan for Foreign Buyers

When a developer changes the project, the foreign buyer should generally follow this sequence: Preserve Original Contract → Preserve Original Brochures and Advertisements → Obtain Original Site and Floor Plans → Obtain Revised Plans → Identify Every Change → Determine Whether Buyer Consent Was Requested → Review Developer’s Modification Clause → Determine Consumer/Prepaid Housing Status → Obtain Technical Expert Review → Calculate Market and Rental Value Difference → Send Timely Written Objection → Avoid Signing Revised Documents Without Review → Determine Whether Performance, Price Reduction, Compensation or Termination Is Appropriate → Investigate Developer Assets if Refund Is Likely → Consider Interim Protection Where Necessary.

How Foreign Buyers Can Protect Themselves Before Buying Off-Plan

The contract should precisely identify the property and commercially important project features. Foreign buyers should seek clear documentation of block, independent-unit number, floor, orientation, net and gross area, balcony, terrace, garden rights, parking, storage, view-related representations, common facilities, technical materials, delivery date and consequences of material project modifications. The more important a feature is to the investment decision, the less it should be left solely to a promotional brochure.

Frequently Asked Questions

1. Can a Turkish developer change the project after I buy an apartment?

Certain technical or legally necessary modifications may be possible, but this does not mean the developer has unlimited authority to make material changes. The contract, applicable regulatory framework and significance of the modification must be reviewed.

2. Can the developer move me to another apartment?

Not automatically. If a specific independent unit was agreed, substituting another unit can create a serious contractual issue. Any contractual substitution clause must also be examined.

3. Can I cancel if the developer removes the swimming pool?

Potentially, particularly if the pool was a material contractual feature and the change substantially affects the transaction. The available remedy depends on the specific agreement and applicable law.

4. What if my apartment becomes smaller?

Obtain an independent measurement and compare it with the contract and plans. A material area reduction may support correction, price reduction, compensation or other remedies.

5. Can I claim compensation if a new building blocks my sea view?

Potentially, especially where the view was specifically represented as an important feature and the project change materially reduces market value.

6. What if the contract says the developer can change the project?

The exact clause must be reviewed. A general technical-modification clause should not automatically be assumed to authorize every fundamental change to the investment.

7. Are foreign buyers protected by Turkish consumer law?

Foreign nationality does not itself exclude consumer protection. Whether the buyer qualifies as a consumer depends primarily on the nature and purpose of the transaction.

8. Can I keep the apartment and demand money instead of cancelling?

Potentially. Where the property remains acceptable but is worth less because of the change, price reduction or compensation may be commercially preferable depending on the applicable legal framework.

9. Should I sign the developer’s revised project plan?

Not before understanding its consequences. Your signature could later be relied upon as evidence that you accepted the modification.

10. What evidence should I collect?

Preserve the original contract, brochures, advertisements, videos, site plans, floor plans, technical specifications, price lists, emails, WhatsApp messages, revised plans, photographs and payment records.

Legal Support for Foreign Buyers Facing Developer Project Changes in Turkey

A developer changing a Turkish property project after the foreign buyer has committed substantial money should not automatically be treated as a routine construction adjustment. The central legal question is whether the developer has made a reasonable technical modification or materially changed the investment the buyer agreed to purchase.

A smaller apartment, different floor, lost sea view, missing swimming pool, reduced parking, eliminated private garden or additional building can materially affect the property’s use, rental potential and resale value. The buyer’s strategy should therefore compare the project originally promised, the project legally approved, the project later revised and the property ultimately delivered.

Firat Fesih Kaya can assist with off-plan property disputes, unauthorized project modifications, apartment size and layout disputes, sea-view claims, missing facilities, parking and garden disputes, developer misrepresentation, contract termination, purchase-price refunds, price reduction, compensation claims and urgent protective measures.

Foreign buyers should object to material changes promptly and avoid signing revised plans, waivers or “full and final settlement” documents without understanding their legal effect. In many cases, the value of the claim depends on proving three things clearly: what the developer originally promised, what the developer changed and how much that change reduced the value of the buyer’s investment.
