What is a mahal listesi?
A mahal listesi (literally "list of spaces") is the table that tells everyone how each room is finished: floor, skirting, walls, ceiling, doors and windows, sanitary fittings and electrical devices. The plan shows where things are; the room schedule says what they are made of. Estimating, procurement and quality checks all draw on it.
It is a statutory project annex. Article 57(29) of the Planlı Alanlar İmar Yönetmeliği (Planned Areas Zoning Regulation), added in February 2022, requires room schedules listing, for each coded space, at least ceiling, floor and wall finishes, door and window frames and leaves, skirting, stair treads and risers, handrails and balustrades, sills and parapets, and surface-mounted fittings such as taps, mixers, basins, lamp holders, switches and luminaires. They are prepared by the architectural, electrical and mechanical designers. Article 57/A also requires taps and mixers limited to 6 l/min for basins and sinks and 8 l/min for showers to be shown in the schedule.
Which columns does it need?
Identity, geometry, finishes and openings. Use short finish type codes (F1, W2, C1 and so on) with full descriptions written once in a legend, so that one material is never spelled two ways and split into two quantities. A workable set: room code, room name, floor and block, net area, perimeter, clear height, floor finish, skirting, wall finish (one type, or per wall: north, east, south, west), ceiling type and suspended ceiling level, wet area and waterproofing, door and window numbers with clear sizes, fittings and devices, and notes.
How are rooms coded?
The usual pattern is a floor prefix plus a sequence number: Z-01 for ground floor (zemin kat) room 1, then 1-05 and so on, with a block letter in front on multi-block sites. A new regulation on digital preparation of design projects (Official Gazette 5 August 2026, no. 33331) requires CAD room numbers to show floor, function and sequence number according to its Annex 3; it takes effect on 1 September 2027. Whatever pattern you use, a code must be unique across plan, schedule, door list and quantities, and must never be reused for a different room after a revision.
How do you take quantities from it?
Each finish uses a different dimension of the room. For Z-01 (living room):
| Item | Formula | Z-01 |
|---|---|---|
| Floor finish | Net area | 31.36 m² |
| Flat ceiling | Net area | 31.36 m² |
| Skirting, gross | Perimeter | 22.40 m |
| Skirting, net | Perimeter − door widths (one 0.90 m door assumed) | 21.50 m |
| Walls, gross | Perimeter × height = 22.40 × 2.70 | 60.48 m² |
| Walls, net | Gross − openings (0.90 × 2.10 door, 1.80 × 1.50 window assumed) | 55.89 m² |
Opening sizes here are illustrative. Whether and from what size openings are deducted depends on the measurement rules of the unit-rate description you price against and on your contract. With a suspended ceiling, wall finishes usually stop at ceiling level, so keep clear height and storey height in separate columns.
These quantities feed straight into the progress payment; see our hakediş guide.
How do you prepare one, step by step?
- Agree the coding rule at project start.
- Label every room on every floor plan with code, name and net area.
- Measure net area, perimeter, clear height and any suspended ceiling level.
- Define short finish type codes with a legend.
- Link door and window numbers from the door and window schedules.
- Complete fittings and devices with the MEP designers.
- Derive floor, wall, ceiling and skirting quantities.
- State the drawing revision and date the schedule belongs to.
Room schedule or room data sheet?
The schedule compares all rooms in one table and is a design deliverable. A mahal künyesi (room data sheet) gathers everything about one room on one page, including door sizes, fittings, levels, notes and photos, and is what you look at standing in that room on site.
What goes wrong most often?
- The schedule is not updated after a drawing revision, so site gets two versions of the truth. Our revision management guide covers distribution.
- Codes or names differ between plan and schedule.
- Gross area used for finish quantities instead of net area.
- One wall finish entered for a room whose walls differ, such as bathroom tiling heights.
- Waterproofing and its upstand height missing in wet rooms; in a bathroom, wall tiling and paint often need two different heights.
- Balconies, terraces, stairs, corridors and plant rooms left off the list, although their finishes are bought and installed too.
- Drawing units misread: a file whose header says mm but is drawn in cm gives areas that are off by a factor of 100.
How Santix handles it
Santix reads DWG, DXF or PDF drawings and suggests rooms, which the architect reviews and approves or corrects. In a November 2026 test, a 7-storey application project DWG was split into 11 sheets and 267 rooms in about 11 minutes; a 58-sheet structural set was split into 58 sheets and correctly received no room suggestions. A file whose header said mm but was drawn in cm was caught from the areas in its room labels. Tap a room to open its data sheet with area, perimeter, wall area, skirting length, finishes, doors and windows, each value marked as read from the drawing, entered by the architect, or edited. An existing schedule in PDF or Excel can be matched to rooms as a suggestion you approve. See room data sheets.

Frequently asked questions
Is a mahal listesi mandatory in Türkiye?
Yes. Article 57(29) of the Planned Areas Zoning Regulation requires room schedules showing finishes, doors and windows, skirting and surface-mounted fittings for every coded space to be attached to the relevant projects.
How do I calculate wall area from a room schedule?
Gross wall area is perimeter times height, for example 22.40 m × 2.70 m = 60.48 m². Openings are then deducted according to the measurement rules of the unit-rate description in your contract.
What is a mahal künyesi?
A room data sheet: one page holding everything about a single room, including area, finishes, door and window sizes, fittings, levels and notes, used on site.
