What is a Construction Contract in Exchange for Land Share in Urban Transformation?

In urban transformation, a construction contract in exchange for a share of the completed building is an agreement between landowners and a contractor for the reconstruction of a property that is a risky structure or within the scope of transformation. In this agreement, the contractor undertakes to construct the building, while the landowners, in return, transfer certain land shares or independent units to the contractor. In legal terminology, this contract is often a construction contract in exchange for land shares . In common parlance, it is expressed as a "contract in exchange for a share of the completed building," "contractor contract," or "urban transformation contract."

This contract is one of the most critical documents in the urban transformation process. Because after the demolition of the risky building, it determines which independent units the owners will receive in the new building, which apartments or shops the contractor will acquire, at what stage the title transfer will take place, the delivery time, rental assistance, security deposit, technical specifications, permits, occupancy permits, delay penalties, defective workmanship, and termination provisions.

The purpose of Law No. 6306 is to regulate the procedures and principles for creating healthy and safe living environments in areas at risk of disaster and on plots and lands containing risky structures. Therefore, a construction contract in exchange for a share of the completed building in urban transformation projects is not merely a commercial construction agreement; it is a strategic legal transaction that directly affects property rights, life safety, urbanization policy, and the economic future of the property owners.

In urban transformation projects, a poorly drafted construction contract in exchange for a share of the completed building can lead to property owners waiting on vacant land for years, contractors abandoning the project halfway through, title transfer disputes, rental assistance problems, defective or incomplete workmanship, inability to obtain occupancy permits, and lengthy lawsuits. Therefore, before signing the contract, not only the contractor's economic offer but also its legal security, technical content, and enforcement mechanisms should be examined in detail.

Legal Nature of Construction Contracts Based on Share of the Land

A construction contract in exchange for a share of the completed building is a mixed-use contract. In one aspect, it resembles a contract for work, as the contractor undertakes to construct a specific building. In another aspect, it involves the transfer of real estate or a promise to transfer real estate, as the landowners agree to transfer specific land shares or independent units to the contractor.

Therefore, construction contracts in exchange for a share of the completed building should not be considered as ordinary service contracts or simple construction agreements. The contract involves construction law, real estate law, contract law, and urban transformation legislation. Especially in contracts made due to risky buildings under Law No. 6306, administrative processes, simple majority decisions, the status of owners who do not participate in the decision, and the land share sales mechanism may also come into play.

In the practice of the Supreme Court, construction contracts in exchange for land shares are considered to be special contracts that combine the elements of a contract for work and the transfer of immovable property. Therefore, the establishment, form, performance, termination, and title deed consequences of the contract should be evaluated more carefully than in ordinary debt relationships.

What form should a construction contract based on a land-for-construction agreement take?

Construction contracts in exchange for a share of the completed building are subject to formal requirements because they involve the transfer of immovable property. In practice, these contracts should be drawn up in the form of a notarized document. Contracts made in simple written form, signed only between the parties, or recorded in the apartment building's minutes book, generally carry a serious risk in terms of validity.

This matter is extremely important. Property owners sometimes sign "preliminary protocols," "memorandums of understanding," "agreement for construction in exchange for land," or "apartment decision documents" with the contractor; however, title transfers or construction preparations begin before a formal contract is signed. While such documents may have certain consequences depending on their specific content, if the actual construction contract in exchange for land is not made in accordance with the formal requirements, serious disputes may arise later regarding claims of invalidity, title transfer issues, and contract performance.

The contract to be drawn up at the notary public should not consist solely of general statements. The contract must include detailed information about the property, the owners' shares in the land, the contractor's obligations, the division of independent units, technical specifications, delivery time, rental assistance, security deposit, penalty clause, title transfer, and termination provisions. The Supreme Court's jurisprudence has established the view that construction contracts in exchange for land shares are subject to formal requirements due to the element of property transfer.

Construction Contract in Exchange for Land Shares under Law No. 6306

In urban transformation projects, construction contracts based on land exchange often come into play for properties identified as risky structures under Law No. 6306. If a building has been deemed risky, this decision has become final, and the evacuation and demolition process has begun, the owners must decide how the new building will be constructed.

In current practice, in plots containing risky structures, even before the demolition of the existing buildings, the reconstruction of the buildings, the sale of shares, redevelopment through methods such as floor-for-floor exchange or revenue sharing, can be decided by a simple majority of the owners in proportion to their shares. This regulation allows for decisions to be made by a simple majority based on land share or ownership ratio, without requiring unanimity in the urban transformation process.

This system aims to prevent transformation projects from being continuously obstructed by a single owner or a minority group of owners. However, a simple majority decision does not grant unlimited power to the majority of owners. The decision must be clear, specific, consistent with the principle of good faith, accurate in terms of land share calculation, and able to be communicated to owners who did not participate in the decision.

If a construction contract in exchange for a share of the completed building is approved by a simple majority, the owners who did not agree with the decision must be duly notified of the decision and the terms of the agreement. Owners who do not review or accept the offer may have their land shares put up for sale. Therefore, the content of the contract is not only a private matter between the signatory owners and the contractor; it is also a document that affects the property rights of the owners who did not agree with the decision.

Investigating the Contractor Before Signing the Contract

One of the biggest risks in a land-for-construction contract is signing a contract with a contractor who lacks the financial and technical competence. The contractor may promise property owners a higher square footage, greater rental assistance, or a shorter delivery time. However, if these promises are unrealistic, the project may be left unfinished.

When selecting a contractor, the following aspects must be thoroughly investigated: the company's trade registry records, capital structure, past projects, completed constructions, occupancy permits, ongoing lawsuits, enforcement proceedings, tax and social security debts, history of bankruptcy or insolvency, technical staff, and financing sources. Even a seemingly large company undertaking numerous projects simultaneously can experience cash flow problems.

Verbal assurances from the contractor alone are insufficient. Security mechanisms such as bank guarantees, performance guarantees, insurance, mortgages, or phased title transfers should be added to the contract. If the contractor abandons the project, relying solely on the right to sue is often inadequate for the property owners. Even if the lawsuit is won, recovering damages can be difficult if the contractor lacks the financial means.

How should the division of independent units be regulated in the contract?

The most important part of a construction contract in exchange for a share of the completed building is the division of independent units. It must be clearly specified which owner will receive which apartment or shop, which independent units the contractor will acquire, how common areas will be used, and how land shares will be allocated.

Simply stating a general ratio like "60% will be given to the owners, 40% to the contractor" in the contract is insufficient. Each independent unit must be clearly indicated, specifying who owns it, its floor, facade, square footage, number of rooms, balcony, storage area, parking space, annexes, and any differences in premium value. Uncertainty, especially regarding units with special value such as shops, ground floor, attic, garden access, parking area, or apartments with views, can lead to serious disputes.

The unit allocation table should be attached to the contract. It should also regulate how the new allocation will be handled if there are any changes to the project. For example, if the number of independent units changes during the licensing phase due to factors such as building density, setback distances, parking requirements, or municipal regulations, the contract should clearly state how the owners' rights will be protected.

Why are Technical Specifications of Vital Importance?

One of the most neglected sections of a construction contract in exchange for a share of the completed building is the technical specifications. However, the technical specifications are a fundamental document that determines the quality of the new building. If the technical specifications are not prepared in detail in the contract, the contractor may use low-quality materials to reduce costs, making it difficult for property owners to object.

The technical specifications should detail the following: concrete class, steel standard, soil improvement, foundation system, exterior wall material, thermal and sound insulation, window frames, glass specifications, door brands, elevator, electrical installation, mechanical installation, fire system, generator, parking lot, landscaping, kitchen cabinets, bathroom materials, floor coverings, common areas, and roof system.

Statements such as "first-class materials will be used" or "luxury construction will be undertaken" are insufficient. The technical specifications must specify which brand or standard of product will be used, whether equivalent products will be accepted, and if so, who will approve them. The technical specifications serve as one of the most important pieces of evidence for property owners in case of future claims of defective or incomplete workmanship.

How should the delivery time be determined?

In a construction contract based on a share of the completed building, the delivery period must be clearly and unambiguously defined. One of the most common mistakes is leaving the start date of the delivery period vague. Does the period begin from the demolition date, the handover of the site, the date of the building permit, the finalization of the construction permit, or the delivery of the land to the contractor? This point must be clearly stated.

It must also be determined which process will be considered completed at the end of the delivery period. Simply completing the rough construction does not constitute delivery. For the owners, true delivery means that the independent units are delivered in a usable condition, in accordance with the contract and technical specifications, and with or able to obtain an occupancy permit.

Force majeure circumstances should also be clearly stated in the contract. Contractors often request extensions due to reasons such as licensing delays, economic crises, increased material prices, municipal procedures, or the inability to find workers. Therefore, it should be stipulated which circumstances will be considered force majeure, under what circumstances the deadline will be extended, and whether rent assistance or late payment penalties will continue if the deadline is extended.

Late Payment Penalty and Rent Assistance

In urban transformation projects, one of the most important safeguards for property owners is the penalty for delays. If the contractor exceeds the delivery deadline, property owners suffer loss of rent, housing expenses, and economic damage. Therefore, the contract should include a clause for monthly delay compensation or penalties for each property owner.

Late payment penalties must be concrete, calculable, and enforceable. Vague statements such as "Damages will be compensated in case of delay" are insufficient. The monthly payment amount for each independent unit, the start date of payment, the account to which it will be paid, and whether it will be offset against rental assistance must be clearly stated.

Rental assistance should also be regulated separately. The rental assistance paid by the contractor differs from the rental assistance provided by the administration. The start date, duration, amount, increase rate, and whether it will continue in case of delay should be determined for the amount to be paid by the contractor. Discontinuing rental assistance when the delivery time is extended creates serious hardship for the property owner. Therefore, rental assistance should be arranged to continue until the construction is actually completed.

Title Transfer Should Be Done in Stages

In a construction contract based on a share of the completed building, the biggest risk for property owners is transferring their land shares to the contractor prematurely. If the contractor acquires a high percentage of title deeds before obtaining permits, starting construction, or reaching a certain level of completion, the property owners' security is severely weakened.

The transfer of title deeds must be done in stages. For example, a certain percentage could be transferred when the building permit is obtained, another percentage when the foundation is completed, another percentage when the rough construction is completed, another percentage when the finishing works are completed, and the final percentage when the occupancy permit is obtained. This way, the contractor cannot acquire the majority of the land shares before completing the work.

Furthermore, the contractor's authority to sell the independent units transferred to him to third parties should also be restricted. If the contractor sells his shares to third parties before the project is completed, good-faith buyers or new parties to disputes may emerge against the property owners. This situation could make it more difficult to complete the project and terminate the contract.

Law No. 6306 stipulates that the establishment of condominium ownership or floor ownership rights for buildings constructed under construction contracts or transfer contracts in exchange for floors can be carried out in the name of the rights holders; however, the contract must specify the independent units allocated to each rights holder. Therefore, the provisions regarding the sharing of independent units and the transfer of title deeds must be clearly stated in the contract.

Guarantees Required from the Contractor

If a construction contract in exchange for a share of the completed building does not include a security clause, the legal security of the property owners is insufficient. If the contractor abandons the project halfway through or acts in breach of the contract, the property owners may suffer serious losses. Therefore, strong security provisions should be included in the contract.

One of the most effective forms of collateral is a bank guarantee letter. Other options include mortgages, sureties, performance guarantees, construction completion insurance, phased title transfers, and penalty clauses. However, the collateral must be genuine and collectible. An abstract commitment from the contractor's own company may not provide sufficient practical security.

Under what circumstances will the security deposit be converted into cash? If construction doesn't begin, if delivery is delayed, if there are discrepancies with the technical specifications, or if the contractor abandons the project? When will the security deposit expire? Will the deposit be returned before the occupancy permit is obtained? These questions must be answered in detail in the contract.

Owners Who Do Not Agree with the Decision and Participation in the Agreement

In urban transformation projects, it is not always possible for all property owners to sign the construction contract in exchange for a share of the completed building. Some property owners may prefer a different contractor, find the contract unfair, or simply not agree with the transformation decision. In such cases, a simple majority decision under Law No. 6306 and the process of notifying the non-participating property owners of the offer may come into play.

Property owners who do not agree with the decision should be notified of the offer containing the terms of the decision and agreement, or the location where the offer can be reviewed. If the property owner does not accept or review the offer after this notification, the land share sale process may begin. The Urban Transformation Directorate's process explanations state that property owners who do not agree with the decision may be notified of the offer via a notary or local administrative announcement, and if it is not accepted within the specified time, their shares may be put up for sale.

Therefore, a construction contract in exchange for a share of the completed building should not only be a document signed by the majority of owners, but also serve as the fundamental document for presenting an offer to dissenting owners. If the contract is vague, lacks security, presents an unfair distribution of shares, or includes incomplete technical specifications, the objections of owners who do not agree with the decision may be strengthened.

Contractor's Breach of Contract and Termination

In urban transformation projects, terminating a construction contract in exchange for a share of the completed building is one of the most complex issues. Property owners may have the right to terminate the contract if the contractor fails to start construction, cannot obtain a permit, leaves the work unfinished, exceeds the delivery deadline, or acts in clear breach of contract.

Under Law No. 6306, termination of a contract due to reasons attributable to the contractor can be decided by a simple majority of the owners in proportion to their shares, if certain conditions arise. In current practice, this process is not handled as a simple termination declaration; instead, it involves stages such as administrative application, assessment, granting a deadline to the contractor, and evaluation of legal requirements.

The termination process should not be rushed. First, the contractor's default must be concretely established. The following should be examined: the stage of construction, which work has not been completed, who is responsible for the delay, whether there are any permit obstacles, whether the property owners have fulfilled their obligations, whether a warning notice has been issued to the contractor, and whether the conditions for termination in the contract have been met.

Following termination, issues such as title transfer, cost of work performed, sales to third parties, contractor's claims, damages to property owners, and selection of a new contractor may arise. Therefore, termination clauses should be drafted from the outset in a strong and enforceable manner.

Owners' Rights in Case of Defective or Incomplete Workmanship

Even if the contractor has delivered the building, the workmanship may be incomplete or defective. Incomplete workmanship means that a task agreed upon in the contract has not been completed at all. Defective workmanship, on the other hand, means that the work done does not conform to the contract, technical specifications, project, permit, or objective quality standards.

For example, using lower quality materials than the brand specified in the technical specifications, inadequate insulation, a substandard elevator, incomplete common areas, a parking lot constructed contrary to the project, insufficient square footage for individual units, or waterproofing problems can all be grounds for claims of defective or incomplete workmanship.

Property owners must prepare a handover report, document any deficiencies in writing, take photographs and videos, and have an expert report prepared if necessary. The contract should clearly state the contractor's obligation to remedy defective workmanship, the timeframe, penalties, and provisions for converting the security deposit into cash.

The Most Common Mistakes in Construction Contracts Based on Land Share

The most common mistake in construction contracts based on land exchange in urban transformation projects is preparing the contract in a general and vague manner. If the division of independent units, delivery time, rental assistance, technical specifications, and title transfer are not clear, disputes become inevitable in the future.

The second mistake is transferring the title deed to the contractor prematurely. A title deed transfer unrelated to the construction progress weakens the most important security held by the property owners.

The third mistake is the failure to obtain security deposits. If the contractor abandons the project halfway through and there is no security deposit, the property owners' losses can only be recovered through lengthy legal processes.

The fourth mistake is the superficial drafting of the technical specifications. When material quality, brand, standards, and application details are not specified, claims of defective workmanship become difficult.

The fifth mistake is the failure to properly notify the owners who do not agree with the decision about the offer. This creates serious problems regarding the sale of land shares and the validity of the majority decision.

The sixth mistake is the omission of termination clauses. If the contractor fails to start the work or abandons the project halfway, the contract should include a clear termination and sanctions mechanism.

Conclusion

In urban transformation projects, a construction contract in exchange for a share of the completed building is one of the most important legal tools enabling property owners to acquire a new building. However, if this contract is not properly prepared, the property rights, economic interests, and housing rights of the owners can be seriously harmed.

This contract is not merely a commercial agreement with the contractor. Under Law No. 6306, the process for assessing risky buildings, the simple majority decision, the status of owners who do not agree with the decision, the transfer of land shares, technical specifications, delivery time, rental assistance, security deposit, delay penalty, defective workmanship, and termination provisions must all be considered together.

The safest approach for property owners is to examine current land registry records and land shares before signing the contract, investigate the contractor's financial and technical qualifications, clarify the division of independent units, prepare a detailed technical specification, carry out the transfer of title in stages, obtain strong guarantees, and prepare the contract in accordance with official procedures.

In conclusion, construction contracts based on land exchange in urban transformation projects should not be rushed. A poorly prepared contract can leave property owners facing years of empty land and legal proceedings after the demolition of a risky building. Conversely, a strong, detailed, and legally compliant contract is the most effective guarantee for property owners to obtain a safe, valuable, and legally compliant new structure.
