How much doors and windows do you need to build a house in Pakistan?
A 150 m² single-storey house in Pakistan needs roughly 24 no. of doors and windows — about 0.16 no. per m² of floor area. That is computed from Pakistan construction conventions, including the local wastage allowance.
Doors & windows quantities for a house in Pakistan, computed from how buildings are actually put up here rather than from a global average. The tables below run from a small 50 m² dwelling to a 400 m² family home, and the method section shows how to reproduce every figure by hand so you can adapt it to your own plan.
Doors & windows by house size in Pakistan
| Floor area | Doors & windows required | Per m² of floor |
|---|---|---|
| 50 m² | 9 no. | 0.18 |
| 75 m² | 13 no. | 0.17 |
| 100 m² | 17 no. | 0.17 |
| 150 m² | 24 no. | 0.16 |
| 200 m² | 32 no. | 0.16 |
| 250 m² | 39 no. | 0.16 |
| 300 m² | 47 no. | 0.16 |
| 400 m² | 63 no. | 0.16 |
Single-storey. The per-m² rate falls as the house grows — a small house has more wall and roof per square metre of floor than a large one, which is why these are computed size by size rather than scaled from a single rate.
Where it goes — 150 m² house
Doors ~1 per 12 m² of floor area | 13 no. |
Windows ~1 per 14 m² of floor area | 11 no. |
What drives the quantity in Pakistan
| Factor | Local value | Effect |
|---|---|---|
| Standard door | 900 × 2100 mm | The size stocked locally. Non-standard sizes are made to order and cost disproportionately more. |
| Standard window | 1500 × 1200 mm | Sets the lintel length and the opening deduction in the masonry quantity. |
| Bathroom window | 600 × 600 mm | Small and high-level for privacy — usually a different unit from the rest. |
| Door density | 1 per ~12 m² | Derived from typical room counts at this floor area. |
| Window density | 1 per ~14 m² | Habitable rooms need light and ventilation; service rooms need less. |
How to calculate it yourself
- 01
Count openings off the plan room by room — this is one quantity you should never estimate from area if a drawing exists.
- 02
As a check, a house of this size normally has about one door per 12 m² and one window per 14 m².
- 03
Schedule each opening with its size, material, handing and ironmongery — the schedule, not the count, is what a joiner prices.
- 04
Measure lintels over every opening: the width plus a bearing each side.
Buying and site notes
- —Order frames early. Joinery lead times routinely exceed the masonry programme and hold up plastering.
- —Fix frames before plastering so the plaster closes onto them — the alternative is a visible gap filled with sealant.
- —Check that door swings do not clash with each other or with switches before the frames are built in.

How much doors and windows does a house need in Pakistan?
+
A 150 m² single-storey house in Pakistan needs roughly 24 no. of doors and windows — about 0.16 no. per m² of floor area. That is computed from Pakistan construction conventions, including the local wastage allowance.
How much doors and windows per square metre in Pakistan?
+
About 0.16 no. per m² of floor area for a single-storey house. The figure is not linear across sizes — a small house has proportionally more wall and roof per m² of floor than a large one, which is why the table above is computed size by size rather than scaled from one rate.
What changes the quantity of doors and windows needed?
+
Standard door (900 × 2100 mm) — The size stocked locally. Non-standard sizes are made to order and cost disproportionately more. Standard window (1500 × 1200 mm) — Sets the lintel length and the opening deduction in the masonry quantity. Bathroom window (600 × 600 mm) — Small and high-level for privacy — usually a different unit from the rest.
Is wastage included?
+
Where it applies, yes — a 5% allowance is carried on the perishable materials (walling units, tiles, paint). Bulk materials like sand and stone carry handling loss instead. Ordering the theoretical quantity with no allowance reliably means a second delivery at a worse price.
How accurate is this for my own house?
+
It is a planning quantity derived from a representative rectangular footprint, so it is the right order of magnitude and internally consistent — good for budgeting and for checking a supplier's list. It is not a measured takeoff of your plan. Upload your dimensioned drawings to get quantities measured off your real geometry and priced in PKR.
Are doors and windows prices included?
+
No, deliberately. Material prices in Pakistan move week to week and vary by region, so a price printed on a static page would be wrong within a month. This page gives you the quantity — take that to two or three local suppliers and the price will be current and competitive.
