Number of Floors Reduced After Urban Transformation: Can Owners Challenge the Decision? (2026 Updated Guide)

Was the number of floors reduced during your urban transformation project in Turkey? Learn whether property owners can challenge the decision, protect replacement apartment rights, dispute contractor changes and challenge zoning restrictions.

A reduction in the number of floors can become one of the most serious disputes in an urban transformation project.

Property owners may have entered redevelopment expecting a new building with the same number of floors as the old building or according to a contractor proposal promising a particular building height. Individual owners may also have been promised replacement apartments on specific floors.

The situation can change when the new architectural project is prepared.

Owners may suddenly be told that fewer floors are permitted, that the zoning rules have changed, that the competent authority will not approve the originally proposed height or that the contractor must redesign the project.

A foreign owner who expected an apartment on an upper floor may then be offered a lower-floor apartment, a smaller property or an entirely different unit.

Owners do not necessarily have to accept such a change without investigation.

However, the right to challenge the reduction depends on why the number of floors was reduced.

The reduction may result from a zoning plan, plan notes, applicable building regulations, a permit decision, technical requirements or simply a contractor’s commercial decision.

These situations involve very different legal remedies.

Lawyer Fırat Fesih Kaya assists foreign property owners with reduced-floor disputes, zoning changes, replacement apartment disagreements, construction permits and contractor disputes arising from urban transformation projects.

Urban Transformation Does Not Automatically Guarantee the Same Number of Floors

A common misunderstanding is that demolishing an eight-floor building automatically creates a right to construct another eight-floor building.

That is not necessarily correct.

An existing building may have been constructed decades earlier according to different planning rules.

The legally permitted height, building form or development density may subsequently have changed.

The replacement project must be evaluated according to the planning and construction framework legally applicable to the new development.

Therefore, the physical characteristics of the old building alone do not determine what may be constructed after demolition.

Why Can the Number of Floors Be Reduced?

There can be several reasons.

A zoning plan may establish a lower maximum building height.

Plan notes may restrict the number of floors.

Changes to road levels, setbacks or building form may affect the architectural solution.

Development-density limitations may make the original number of floors impractical.

Technical or safety requirements may also influence the approved design.

Alternatively, the contractor may simply prefer a different architectural configuration.

The legal strategy depends on identifying the real reason.

Ask for the Official Basis of the Reduction

Owners should not rely solely on a contractor’s statement that “the authority reduced the floors.”

The official basis should be identified.

Which zoning provision requires the reduction?

Did the zoning plan change?

Did a plan note change?

Was the permit application rejected?

Was the architectural project revised voluntarily?

Did the authority issue a written decision?

This distinction is crucial because an administrative planning decision may potentially be challenged, while a voluntary contractor design change primarily raises contractual issues.

Check the Current Zoning Plan and Plan Notes

The applicable zoning plan should be reviewed first.

But examining only the plan map may not be enough.

Plan notes can contain detailed provisions affecting building height, floor structure and other development conditions.

Owners should therefore obtain a technical analysis showing what building height and configuration are actually permitted on the parcel.

A contractor’s preliminary design should never substitute for this analysis.

Was the Old Building Legally Higher?

An old building may have more floors than currently permitted.

That does not automatically establish a right to reconstruct the same height.

The owner should investigate when the existing building was constructed, which planning rules applied at that time and whether the building was lawfully permitted.

The current planning position should then be compared with the historical position.

This comparison can explain why the replacement project differs from the old building.

What If the Contractor Promised the Same Number of Floors?

This creates a separate contractual question.

Suppose the contractor signed an agreement promising a ten-floor replacement building and specifically allocated an apartment on the eighth floor to an owner.

If the approved project later contains only seven floors, the contractor cannot necessarily solve the problem simply by allocating another apartment without considering the agreement.

The reason the original promise cannot be performed must be investigated.

A Specific Floor Allocation Can Have Economic Value

Apartment allocation is not merely about apartment numbers.

An upper-floor property can have substantially different characteristics from a lower-floor property.

It may have a better view.

It may receive more natural light.

It may have greater privacy.

Noise conditions may differ.

The market value may therefore be higher.

An owner promised a particular floor should not evaluate a proposed replacement only by comparing square meters.

Can the Contractor Move an Owner to a Lower Floor?

Potentially, depending on the contract and circumstances, but not necessarily unilaterally.

If the redevelopment agreement specifically identifies the replacement unit, floor or other characteristics, changing them can raise contractual issues.

Where a planning restriction genuinely makes the original allocation impossible, the parties may need to negotiate a revised allocation.

The difference in economic value should be considered.

What If the Contractor Knew About the Floor Restriction?

This is particularly important.

Suppose the zoning framework already limited the new building to seven floors when the contractor promised owners a ten-floor building.

The contractor later claims that the authorities unexpectedly reduced the number of floors.

Owners should investigate whether the restriction was actually foreseeable from the beginning.

A contractor’s failure to conduct adequate planning due diligence should not automatically be treated as an unexpected owner risk.

Contractor Marketing Materials Can Become Relevant

Before signing, contractors may distribute drawings, presentations and proposed apartment-allocation schedules.

These documents should be preserved.

Their legal significance depends on the contract and circumstances, but they can help establish what was represented to owners when the agreement was negotiated.

Owners should also preserve written messages concerning promised floors, apartment positions and project characteristics.

What If the Zoning Rules Changed After the Agreement?

The analysis becomes more complicated where the original project was legally feasible when the agreement was signed but planning rules later changed.

The redevelopment agreement should be reviewed for provisions dealing with zoning changes and administrative restrictions.

The parties may have allocated this risk expressly.

If the agreement is silent, the effect of the subsequent change requires a broader contractual analysis.

Timing of the Planning Change Is Critical

Owners should establish a precise chronology.

When was the redevelopment agreement signed?

When was the architectural project prepared?

When was the permit application submitted?

When did the planning rule change?

Was a construction permit already issued?

Had construction started?

These dates can materially affect both administrative and contractual rights.

What If a Construction Permit Had Already Been Issued?

The existence of a lawfully issued construction permit can substantially affect the legal assessment.

However, a permit should not automatically be treated as creating an absolute right to complete every element of the project regardless of later events.

The legality and validity of the permit, commencement of construction and factual level reached by construction can all become relevant when acquired rights are considered.

Owners should preserve the complete permit and project file.

Does a Previous Permit Create an Acquired Right to the Old Number of Floors?

Not necessarily.

Acquired rights in planning law require careful case-specific analysis.

The existence of a previous zoning rule alone does not automatically create a permanently protected right.

Similarly, merely obtaining a permit may not resolve every acquired-right question.

The permit’s legality, commencement of construction and actual progress can be significant.

Owners should therefore avoid relying on broad statements such as “we had a permit, so the old floor number is permanently guaranteed.”

Can Owners Challenge the Zoning Decision?

Potentially, yes.

If the reduction results from a zoning plan or plan amendment, the relevant administrative act can potentially be challenged where sufficient legal grounds exist.

The plan may need to be examined for compliance with planning principles, statutory requirements, public interest and technical planning standards.

A reduction in building height alone does not automatically prove illegality.

A technical and legal planning analysis is generally necessary.

Planning Challenges Are Subject to Strict Timing

Owners should investigate the planning decision as soon as they discover the reduction.

The approval and announcement history should be obtained.

Available administrative objection mechanisms should be considered.

Judicial deadlines must also be identified.

Waiting until construction begins under the revised project can substantially weaken the owner’s practical position.

Does Filing a Lawsuit Stop the Reduced-Floor Project?

Not automatically.

Filing proceedings against a planning decision should not be assumed to suspend implementation by itself.

Where immediate protection is necessary, the legal requirements for interim judicial relief may need to be evaluated separately.

This can be especially important where a permit for the revised project is about to be issued or construction is about to begin.

Can Owners Challenge the Construction Permit?

Potentially, depending on the circumstances.

If the dispute concerns how the applicable zoning plan was implemented through a particular construction permit, the permit itself may become relevant to the legal challenge.

Owners must distinguish between challenging the underlying zoning plan and challenging an individual administrative decision based on that plan.

The correct target of proceedings depends on the nature of the alleged illegality.

What If the Contractor Voluntarily Reduced the Number of Floors?

This is different from an authority-imposed restriction.

A contractor may redesign the project because a different building configuration is more profitable or easier to construct.

If planning law permits the originally agreed project, the contractor should not automatically be able to use its own commercial preference to disregard contractual apartment allocations.

The redevelopment agreement becomes the primary source of owner protection.

Ask Whether the Original Project Is Still Legally Possible

This question can clarify many disputes.

Owners should obtain an independent technical opinion on whether the originally promised number of floors is still legally and technically feasible.

If it is feasible, the contractor should explain why the project was changed.

If it is not feasible, owners should determine why and when the restriction arose.

Can the Majority of Owners Approve a Building With Fewer Floors?

The current urban transformation framework permits important new-application decisions on risky-building parcels to be made, where unanimity cannot be achieved, by the applicable simple majority calculated according to ownership shares.

This can be relevant where owners approve a revised redevelopment proposal.

However, majority decision-making and individual contractual rights should not automatically be treated as identical questions.

A majority decision does not necessarily erase every existing contractual claim arising from a promised replacement unit.

Non-Participating Owners Should Not Ignore the Majority Process

An owner who disagrees with the revised project should nevertheless take the formal process seriously.

Under the current framework, the majority decision and agreement conditions can be formally communicated to owners who do not participate.

Failure to respond within the applicable process can expose a dissenting owner’s ownership share to the statutory sale mechanism where the legal requirements are satisfied.

Therefore, an owner should challenge the problem actively rather than simply refusing to communicate.

Can the Number of Floors Be Increased Again?

Potentially, if the applicable planning framework permits it or a lawful planning amendment later changes the development conditions.

However, owners should never base financial decisions on speculative promises that the number of floors “will definitely increase.”

Until a legally effective planning basis exists, expected future development rights should be treated cautiously.

What If Fewer Floors Mean Smaller Apartments?

A reduction in floors can reduce total available construction area depending on the planning structure.

The contractor may then propose smaller replacement apartments.

Owners should compare the new unit with the original contractual allocation.

Net area, gross area, floor, orientation, parking, storage and technical specifications should all be reviewed.

The reduction should be quantified rather than described generally.

What If Fewer Floors Mean Some Owners Lose Their Promised Units?

This can create an especially serious allocation dispute.

For example, the original project may promise replacement units on floors that no longer exist under the revised project.

The contractor and owners will then need a legally sustainable reallocation structure.

Affected owners should determine the value of what they were originally promised and the value of what is now being offered.

Independent Valuation Can Be Important

Two apartments with identical floor areas can have different market values.

If an owner is moved from an upper floor to a lower floor, independent valuation can help quantify the difference.

The valuation can consider location within the building, view, orientation and other economically relevant characteristics.

This may become important in settlement negotiations or compensation claims.

Can Owners Demand Compensation?

Potentially.

Whether compensation is available depends on the source of the loss.

If the contractor breached a contractual promise without valid justification, contractual compensation may be considered.

If an allegedly unlawful administrative decision caused the loss, a different legal framework may apply.

The mere fact that the number of floors decreased does not automatically establish a compensation claim.

What If the Contractor Delayed the Permit Application?

This scenario deserves particular attention.

Suppose a higher building was legally possible when the agreement was signed.

The contractor was required to proceed with the permit process but delayed without justification.

During that delay, the planning framework changed and fewer floors became permissible.

Owners should investigate whether timely contractor performance could have preserved the more favorable project.

Contractor Delay Can Create Separate Liability

If the contractor’s delay caused or materially contributed to the loss of a more valuable redevelopment opportunity, potential contractual liability may arise.

Owners may need to establish the original planning position, contractor’s obligations, delay period, later planning change and resulting financial loss.

Expert evidence can be particularly important.

Can the Contractor Demand Additional Money Because There Are Fewer Floors?

Not automatically.

The contractor may argue that fewer floors mean fewer saleable units and therefore insufficient revenue to finance construction.

This may be economically true but does not automatically establish an owner debt.

The redevelopment agreement must be examined to determine who assumed the risk.

A revised feasibility calculation should also be requested.

Compare Owner Losses With Contractor Losses

Owners should determine how the revised project distributes the consequences of the floor reduction.

Have owner apartments become smaller?

Have contractor units also been reduced?

Has the contractor preserved its expected economic return while shifting most of the loss to existing owners?

A transparent before-and-after allocation can reveal whether the proposed solution is commercially and contractually justified.

Do Not Sign a Revised Apartment Allocation Without Review

A revised allocation schedule can fundamentally alter an owner’s rights.

Owners should compare the original and proposed apartment.

Floor, area, orientation, view, parking, storage and ownership share should be checked.

The document should also be reviewed for hidden provisions concerning additional payments, revised delivery deadlines or waiver of compensation claims.

Do Not Automatically Waive Existing Delay Claims

A contractor may combine the floor reduction with a broader restructuring of the redevelopment agreement.

Owners may be asked to accept a new project and a new completion date.

The amendment may also release the contractor from previous delay liability.

Existing claims should therefore be identified and valued before any revised agreement is signed.

Foreign Property Owners Face Additional Risks

Foreign owners living abroad may discover the floor reduction only after other owners have already negotiated a revised project.

They may receive documents requesting an urgent signature without receiving the underlying planning documents.

Foreign owners should request the official planning basis, revised architectural project, owner decision, contractor proposal and original agreement before accepting the change.

Foreign Owners Can Challenge Relevant Decisions

Foreign nationality does not prevent an owner from exercising available property, contractual or administrative-law rights.

The critical issue is usually timing.

A foreign owner living abroad should therefore ensure that official notices and owner-meeting developments are monitored.

A carefully drafted power of attorney can allow representation where necessary.

Power of Attorney Should Not Be Unnecessarily Broad

Authority to obtain planning documents or attend an owner meeting does not necessarily need to include authority to accept a materially inferior replacement apartment.

Owners should understand whether their representative can modify apartment allocation, recognize additional debt, waive compensation or transfer property rights.

These powers can have substantial economic consequences.

Buyers Should Investigate Floor Restrictions Before Purchasing

A foreign investor considering buying property in a building expected to undergo urban transformation should investigate the current development conditions before purchase.

The existing building may contain more floors than can be reconstructed today.

A seller’s statement that “you will receive the same floor after transformation” should not substitute for planning due diligence.

The current zoning framework and any redevelopment agreement should be examined.

Never Rely Solely on a Contractor’s Conceptual Drawing

A conceptual project can be useful during negotiations, but it is not necessarily the final legally approved project.

Owners should distinguish between marketing drawings, preliminary architectural proposals and an approved project forming part of the permit process.

The contractor agreement should clearly define what happens if the final approved project differs materially from the preliminary proposal.

Evidence Owners Should Preserve

Owners should retain the original redevelopment agreement and all annexes.

The original apartment-allocation schedule should be preserved.

Previous and current zoning documents can be important.

Plan notes, construction permits and architectural projects should be collected.

Written contractor representations concerning floor numbers should also be retained.

Owner-meeting decisions, formal notices, revised project documents and correspondence should be organized chronologically.

2026 Practical Legal Strategy

The first priority is determine exactly why the number of floors was reduced. A zoning restriction, administrative permit decision and voluntary contractor redesign require different responses.

The second priority is obtain the current zoning plan, applicable plan notes and technical calculation of legally permitted building height and development capacity.

The third priority is compare the current planning position with the position that existed when the redevelopment agreement was signed.

The fourth priority is establish the chronology of the agreement, permit application, planning change, permit issuance and construction commencement.

The fifth priority is review whether the contractor expressly promised a particular floor, apartment position or building configuration.

The sixth priority is determine whether the contractor knew or should reasonably have known about the relevant floor restriction when the agreement was signed.

The seventh priority is consider administrative remedies promptly if the floor reduction results from a potentially unlawful planning or permit decision.

The eighth priority is do not ignore the formal majority and notification process merely because you disagree with the revised project.

The ninth priority is calculate the economic difference between the originally promised apartment and the replacement unit now being offered.

The tenth priority is do not sign revised allocations, additional-payment protocols or waivers until the effect on existing contractual and compensation rights has been assessed.

The central principle is clear: a reduction in the number of floors does not automatically mean that property owners have no remedy. Owners must first determine whether the reduction results from planning law, a permit decision, a later zoning change, contractor delay or a voluntary project redesign. The appropriate challenge depends on the source of the reduction and the stage reached by the redevelopment project.

Frequently Asked Questions

1. Can an urban transformation project have fewer floors than the old building?

Yes. The replacement project may be subject to planning conditions different from those that applied when the old building was constructed.

2. Do I have an automatic right to the same floor in the new building?

Not merely because you occupied that floor in the old building. However, a redevelopment agreement specifically promising a particular replacement floor can create important contractual rights.

3. Can I challenge a zoning decision that reduces the number of floors?

Potentially, yes. If the reduction results from a planning decision, available administrative objection and judicial remedies should be examined promptly.

4. Does an existing construction permit guarantee the previous number of floors?

Not necessarily. The permit’s legality and validity, commencement of construction and project progress can affect the analysis.

5. Can the contractor move my replacement apartment to a lower floor?

The contractor should not automatically be assumed to have unilateral authority to alter a specifically agreed allocation. The agreement and reason for the project change must be reviewed.

6. Can I claim compensation if my new apartment is on a less valuable floor?

Potentially, depending on the contractual obligations, cause of the change and resulting proven loss.

7. Can the contractor ask for more money because fewer floors can be constructed?

Not automatically. The redevelopment agreement and allocation of planning risk should be examined before owners accept an additional financial obligation.

8. What if the contractor delayed obtaining the permit before the height restriction changed?

Potential contractor liability should be investigated if timely performance could have avoided or reduced the loss.

9. Can the majority of owners accept the revised project?

The current urban transformation framework allows important new-application decisions to proceed through the applicable simple majority based on ownership shares where unanimity is unavailable. However, majority procedure and individual contractual claims must still be analyzed separately.

10. Can a foreign owner challenge the reduction from abroad?

Yes. A foreign owner can exercise available contractual, property and administrative-law rights through appropriately authorized representation, subject to applicable procedures and deadlines.

Legal Assistance When the Number of Floors Is Reduced

A reduction in the number of floors can affect much more than the external appearance of a new building.

It can eliminate promised apartments, move owners to less valuable floors, reduce total construction capacity and change the financial balance between owners and the contractor.

Owners should therefore never accept the explanation that “the floors were reduced” without identifying the legal and technical reason.

The zoning plan, plan notes, permit history, redevelopment agreement, apartment-allocation schedule and revised architectural project should be examined together.

For foreign owners managing property from abroad, independent verification is particularly important before accepting a lower-floor apartment or signing a revised redevelopment agreement.
