The most permanent decision in building a house comes before design: the land. Plans and facades can change, but the slope, orientation and building rights of a plot cannot. The nine checks below are the questions an architect asks when first looking at a plot. We recommend answering all of them before you buy.
1. Zoning status
Ask the municipality for the zoning status document (imar durumu). It states the floor area ratio, site coverage, number of storeys, height limit and setbacks. Two plots of the same size may allow two storeys on one and a single storey on the other. A listing that says "zoned for villas" is no substitute for this document.
2. Title type: building plot or field?
Building a house on land registered as a field (tarla) is far more limited and complicated than on a registered building plot (arsa). On shared titles (hisseli tapu), building is close to impossible without every co-owner's consent. Always check the title record and any annotations on it.
3. Road frontage and access
Check that the plot fronts a public road defined in the zoning plan. Not every track on a map is a legal road. Whether a concrete mixer and a crane can reach the plot during construction matters as much as whether you can reach your house in winter.
4. Slope
Sloping plots produce some of the best views, but they also raise the cost of retaining walls, excavation and foundations. A gentle slope is often an advantage: a floor can be set into the ground and the garden reached from two levels. On a steep slope, much of the budget can end up underground.
5. Soil
A soil survey is required for the permit anyway, but you can anticipate its results before buying. Ask about the foundations of nearby buildings, whether the area is backfilled and how close it is to a stream bed. Weak ground directly increases foundation costs.
6. Orientation and sun
Living spaces with southern light change both winter heating costs and how the house feels. If the view faces north, finding a plan that captures light and view together becomes the main task of the design. Visiting at different times of day is the easiest way to see which hills and trees cast shade.
7. The view and future neighbours
Today's view has to be read together with the building rights of the empty plot next door. Knowing how much the neighbouring plots may build tells you whether your view will become a wall in a few years.
8. Utilities
- Is there mains water, or will you need a well or a tank?
- How far away is the electricity line?
- Is a sewer connection possible, or will you need a septic system?
- Do gas and fibre internet reach the area?
On rural plots, bringing utilities in can cost far more than expected.
9. Protected areas and forest boundaries
Plots near forest boundaries, heritage sites, the coastline or drinking-water basins can carry additional restrictions. In areas such as the northern forests of Istanbul this check is especially important. The opinions of the relevant authorities determine both what you can build and how long it will take.
The land is the first design decision, and the only one you cannot revise.
Frequently asked questions
How do I check a plot's zoning in Turkey?
The zoning status document is issued by the planning department of the municipality the plot belongs to. Many municipalities also offer an online e-imar query. For official purposes, use a current, certified copy.
Can I build a house on agricultural land?
Building on land registered as a field is much more restricted than on a zoned plot and depends on permits. The rules vary with the region and the class of agricultural land. Get the municipality's and an architect's opinion before buying.
When should I involve an architect?
Ideally before you decide to buy. A short assessment based on the zoning document, the title record and the plot's location shows what kind of house is possible there and what extra costs to expect.
