Key Points in a Construction-for-Flats (Kat Karşılığı) Contract

How to set the share ratio, delivery deadline, guarantees and penalty clauses in a construction-for-flats contract, step by step.

One of the most common ways for landowners to develop their plot is the construction-for-flats model. The owner provides the land, the contractor builds, and the finished units are shared at a pre-agreed ratio. But a safe process depends on a well-prepared contractor agreement. Here are the key points to watch.

What Is Construction-for-Flats?

In this model the landowner is paid not in cash but with a share of the finished building. The owner becomes a property holder without taking on construction cost risk, while the contractor starts building without paying for the land. It looks win-win, but the balance lies entirely in the contract details.

How Is the Share Ratio Set?

The most critical clause is the share ratio, based on location, floor area ratio, local sale prices and construction cost. Which specific unit belongs to whom (floor, facade, number) must be written clearly. "Equal sharing" is not enough; the flats should be listed one by one.

Delivery Deadline and Penalty Clauses

The contract must state a clear completion date and a daily or monthly penalty for delay. It should also include termination and compensation clauses that protect the owner if the contractor fails to finish or abandons the project.

Guarantees

The owner's strongest safeguard is tying deed transfer to construction progress. Deeds should not be transferred to the contractor up front; shares should pass stage by stage. A bank guarantee letter, mortgage and a notarized contract add further security.

Common Mistakes

Relying on verbal agreements, signing without a specification list, transferring the deed in advance, and omitting penalty clauses are the most frequent and costly errors. Always sign before a notary and with expert or legal review.
