The regulatory minimums come from Article 29 of Turkey's Planned Areas Zoning Regulation: living room 12.00 m², bedroom 9.00 m², kitchen 3.30 m², bathroom 3.00 m², toilet 1.20 m². The article also sets minimum room widths. Official text: mevzuat.gov.tr

Let's shape your space program together for your projectThis total is only the net m² of living spaces. Corridors, wall thickness and shared areas are not included; it does not replace an actual space program. Source:Minimum m² for bedrooms and living rooms.
How is a home's net area requirement calculated?
A home's total net area requirement depends on how many rooms it contains and the accepted minimum/comfortable m² range for each room type. This tool uses the table from our article on minimum m² for rooms and living spaces to calculate the total net area, as both a minimum and a comfortable figure, for the room counts you select.
A living room is assessed at 12-28 m², a primary bedroom at 12-18 m², a child's/guest bedroom at 9-14 m², a kitchen at 4-14 m², a bathroom at 3.3-8 m², and a WC at 1.2-2.5 m²; a counter next to each room type lets you set how many you want.
The difference between minimum and comfortable
Minimum values are the smallest dimensions a room needs to function; the comfortable range describes sizes that feel spacious in daily use, leaving room for furniture and circulation. Both ends of the total are shown so you can compare two budget or plot scenarios.
These figures come from a general reference table. Actual room sizes will vary with household size, furniture layout and personal preference.
What this doesn't cover
This total is strictly the net m² of living spaces. It excludes corridors, wall thickness, stair voids and shared areas, and it is not a substitute for an actual architectural space program (a building's gross area typically runs about 1.2-1.4 times its net area).
In an initial consultation, MEEZ Mimarlık builds a real space program around your lifestyle. Starting from numbers like the ones you've just tried, we shape a clear plan that fits your plot and budget.

How big should a living room be?
The tool assesses living rooms in the 12-28 m² minimum/comfortable range. The minimum is the smallest size the room needs to function; the comfortable range leaves room for furniture and circulation.
What's the difference between net area and gross area?
The total in this tool is strictly the net m² of living spaces. It excludes corridors, wall thickness, stair voids and shared areas. A building's actual gross area typically runs about 1.2-1.4 times its net area.
What's the difference between the minimum and comfortable ranges?
Minimum values are the smallest dimensions a room needs to function; the comfortable range describes sizes that feel spacious in daily use, leaving room for furniture and circulation. Both ends of the total are shown so you can compare two budget or plot scenarios.
What m² range is used for the kitchen and bathroom?
Kitchens are assessed at 4-14 m², bathrooms at 3.3-8 m², and WCs at 1.2-2.5 m²; a primary bedroom is 12-18 m² and a child's/guest bedroom is 9-14 m². These figures come from the table in our article on minimum m² for rooms and living spaces.
How do I work out a "3+1" or "2+1" home with this tool?
In Turkey homes are described by room count: "3+1" means three rooms plus a living room. You build that up space by space in the tool. For a 3+1, one living room, one main bedroom, two child/guest rooms, plus kitchen, bathroom and WC; for a 2+1, the same set with one room fewer. The tool adds up the minimum and the comfortable range separately for each space, so it never imposes a single "ideal square metre" figure; where you sit within that range is your decision, based on your household and how you live. Remember that the total covers the net area of living spaces only: corridors, wall thickness and stairwells are not included, so the gross area comes out higher.
