Zameen's Lahore model updated 9 September 2026 shows PKR 36.46 lakh for a 1,215 sq ft double-storey 3 Marla grey structure at PKR 3,001/sq ft. This site's illustrative Lahore model gives PKR 43.14 lakh for the same covered area. The area is comparable; the published inclusion detail is not, so these totals do not form a contractor-price range.
The 90% example is not a coverage permission
The 1,215 sq ft example uses 90% coverage only to reproduce a published comparison. Your approved drawing and measured floors determine the area you can price for construction.
Key assumptions
- 3 Marla × 225 sq ft = 675 sq ft plot area.
- 90% planning coverage on two floors = 1,215 sq ft covered area.
- The 90% is chosen only to reproduce the external example's covered area; it is not a statement of permitted coverage.
- Website model: Lahore, standard quality, double storey, no basement.
Small-plot warning: three traditional Marla is 816.75 sq ft, while three scheme Marla at 225 sq ft is 675 sq ft. The approved setbacks and stair openings—not the label—determine buildable area.
Worked calculation
The website calculator follows one auditable rule:
Estimated grey-structure cost = total covered construction area × applicable cost per square foot
Plot area = 3 × 225 = 675 sq ft
Covered area = 675 × 0.90 × 2 = 1,215 sq ft
Estimate = 1,215 × PKR 3,551 = PKR 4,314,465 (PKR 43.14 lakh)

Inclusion matrix
| Work item | Zameen model | GreyStructureCalc model |
|---|---|---|
| Foundation, RCC, walls, roof and plaster | Explicitly included under “Foundation & Structure” | Intended core shell scope; no line-item BOQ or allocation |
| Rough plumbing | PKR 5.15 lakh itemized | Conditional on the project quotation |
| Rough electrical | PKR 1.03 lakh itemized | Conditional on the project quotation |
| Roof insulation, termite work and waterproofing | Combined PKR 35,980 item is disclosed | No separate allowance |
| Tanks, taxes and external works | Not fully established by the source snapshot | Not established; budget separately unless written into a quotation |
| Labour | PKR 5.84 lakh total labour is disclosed | Illustrative all-in rate; labour is not split out |
Use the totals as separate model outputs until a common drawing and inclusion schedule makes them like-for-like.
Compact-house scope needs extra clarity
On a 3 Marla project, stairs, tanks, service shafts and wet areas occupy a large share of the build. The grey quotation should identify foundations, RCC, staircase, roof, masonry, plaster and each rough service rather than relying on one short label.
Costs outside the structural shell
Plot purchase, design and approvals, utility work, unusual access and ground treatment require separate allowances. Doors, windows, flooring, paint, kitchens, storage, sanitaryware and electrical fixtures remain finishing costs.
Checks before awarding a compact-house contract
- Verify that both bidders count the narrow stair and mumty the same way.
- Confirm material storage, lifting and street-access responsibilities.
- Match the number of bathrooms, kitchens and concealed service runs.
- Compare structural and masonry specifications item by item.
- Ask for a total, exclusions and variation method—not only a headline rate.
Keep the custom input clean
When a current 3 Marla Lahore rate covers this actual design, enter it directly. The calculator intentionally bypasses its quality, city and storey adjustments for that custom all-in input.
What changes the local result
On a narrow plot, stair placement, party-wall conditions, material handling and a relatively high number of kitchens or bathrooms per square foot can affect cost. Confirm ventilation, parking and setbacks before assuming 90% coverage.
A smaller approved layout changes the budget
Suppose the final drawings show 520 sq ft on the ground floor, 480 sq ft above and a separately counted 55 sq ft enclosed stair room. These invented areas demonstrate the method; they are not a recommended or approved 3 Marla plan.
Measured covered area = 520 + 480 + 55 = 1,055 sq ft
Illustrative shell amount = 1,055 × PKR 3,551 = PKR 3,746,305
Rounded display = PKR 37.46 lakh
This is 160 sq ft less than the 1,215 sq ft example and reduces that model amount by PKR 568,160, or PKR 5.68 lakh. Actual savings depend on which work disappears: stairs, tanks and service connections may still be needed even when a bedroom becomes smaller.
Price the work around a narrow site
Ask the bidder where materials will be received and stored, how concrete and steel will reach each level, and who pays for extra handling. Record any limitations on deliveries or temporary use of adjoining space before the contract. A small site may need more deliveries rather than one large stockpile.
Agree how existing neighbouring walls and services will be documented before excavation. Any protection or support should follow the project's professional advice and be priced in the correct work item. It should not emerge as an unexplained percentage after work starts.
Check the cost of independent portions
Two separate portions can require a second kitchen, additional service runs and separate access. Ask the designer to show those routes and the bidder to price them. Keeping the same floor area while doubling wet areas does not guarantee the same per-square-foot cost.
If only one floor is to be built now, record the future intention in the design brief. Price today's contracted work separately from a later floor, while having the building's structural requirements resolved for the intended project. A cost-saving choice should not become an undocumented change to the structural design.
Questions people ask
How much does it cost to build a 3-Marla grey structure house?
For the stated 1,215 sq ft Lahore example, two different-scope published models show PKR 36.46 lakh and PKR 43.14 lakh. Treat them as separate model outputs, not a market range.
Is 90% coverage allowed on every 3 Marla plot?
No. It is only a worked-example assumption. The applicable authority, society and approved plan control coverage and setbacks.
Why might 3 Marla cost more per square foot?
Stairs, wet areas, tanks and service connections are concentrated into a smaller area, while access and storage can be more difficult.
What if the final covered area is below 1,215 sq ft?
Replace the example area with the measured total of the actual floors. For instance, 1,055 sq ft at the illustrative PKR 3,551/sq ft equals PKR 3,746,305; fixed scope items still need to be checked.
