Footprint coefficient: the ratio of the building’s ground footprint to the plot area. On a 500 m² plot with TAKS 0.40, up to 200 m² of footprint is allowed.

Floor-area ratio: the ratio of total floor area counted toward the ratio to the plot area. Plot × KAKS gives the total buildable floor area.

The maximum building height or storey limit stated in the plan.

The minimum distance a building must keep from plot boundaries (front, side, rear).

Areas not counted toward the floor-area ratio under regulation (e.g. shelter, parking, lift and stair shafts). Scope depends on regulation.

Gross area includes walls and the common-area share; net area is the usable area inside the apartment.

The share of an independent unit in the main property (land) under condominium ownership.

The official document confirming a building was completed in line with its permit and design, allowing it to be used.

01Zoning Calculator · TAKS / KAKS (FAR)

Calculates the maximum footprint, total construction area and approximate storey count from the plot area and zoning coefficients.

Plot area (m²) TAKS (footprint coefficient) e.g. 0.40 KAKS / FAR (floor-area ratio) e.g. 1.60 Max. storeys (optional) Leave 0 if unknown Non-FAR area ratio (optional) (%) Stairs, lifts, shelters, parking etc. as allowed by regulation

Maximum footprint: —m²
Maximum floor area (FAR): —m²
Additional non-FAR area: —m²
Total gross construction area: —m²
Approx. storeys (KAKS ÷ TAKS): —

For general information only. The parcel’s zoning status and plan notes are authoritative.

02Flat-for-Land Share Calculator

Calculates the gross-area and approximate apartment shares of the landowner and the contractor from the total area and sharing ratio.

Total gross construction area (m²) Landowner share (%) Set in the agreement Common-area ratio (%) Gross − net difference (stairs, corridors, lifts etc.) Average apartment gross area (m²)

Landowner share (gross): —m²
Contractor share (gross): —m²
Landowner share (net): —m²
Approx. apartments to landowner: —
Approx. apartments to contractor: —

Actual sharing varies with apartment types, floor positions and contract terms. This is a preliminary estimate only.

03Approximate Construction Cost

Calculates the approximate build cost and additional expenses from the gross area and your own unit-cost input.

Gross construction area (m²) Unit cost (₺/m²) Enter the current unit cost yourself (the ministry’s approximate unit costs are one reference) Additional expenses (permit, fees, inspection, design) (%) Contractor margin / overheads (%)

Build cost: —₺
Additional expenses: —₺
Margin / overheads: —₺
Grand total: —₺
Total cost per m²: —₺/m²

Percentages are sample values; adjust them for your project. The result is not a quotation.

04Gross ↔ Net Area Conversion

Enter the common-area share to convert gross to net area or net to gross area.

Gross area (m²) Net area (leave 0 to derive from gross) (m²) Common-area share (%)

Net area: —m²
Gross area: —m²
Common area: —m²

The common-area share typically varies between 12–25% depending on building type.

05Concrete and Rebar Quick Estimate

Estimates concrete volume and approximate rebar quantity for slabs, foundations or shear walls.

Plan area (m²) Thickness (cm) Waste allowance (%) Rebar ratio (kg/m³) Varies by structural element

Concrete volume: —m³
Order quantity incl. waste: —m³
Approx. rebar: —kg
Approx. rebar (tonnes): —t

Does not replace the structural design; a rough quantity estimate only.

Glossary

TAKS: Footprint coefficient: the ratio of the building’s ground footprint to the plot area. On a 500 m² plot with TAKS 0.40, up to 200 m² of footprint is allowed.
KAKS / FAR: Floor-area ratio: the ratio of total floor area counted toward the ratio to the plot area. Plot × KAKS gives the total buildable floor area.
Max. height: The maximum building height or storey limit stated in the plan.
Setback: The minimum distance a building must keep from plot boundaries (front, side, rear).
Non-FAR area: Areas not counted toward the floor-area ratio under regulation (e.g. shelter, parking, lift and stair shafts). Scope depends on regulation.
Gross / Net area: Gross area includes walls and the common-area share; net area is the usable area inside the apartment.
Land share: The share of an independent unit in the main property (land) under condominium ownership.
Occupancy permit: The official document confirming a building was completed in line with its permit and design, allowing it to be used.

Calculations and definitions on this page are for general information; for official procedures the municipality’s zoning status, plan notes and current legislation prevail.
