4 Kanal House Construction in Lahore, Islamabad and Rawalpindi
A 4 Kanal house is a large building before it is a large house. On two 2 Kanal plots joined in DHA Lahore, the 2026 regulations allow about 20,485 sq ft above ground and a basement of up to 11,340 sq ft. That is close to 31,800 sq ft of construction, or roughly four 1 Kanal houses under one roof.
We build houses at this scale in Lahore, Islamabad and Rawalpindi, and one of them is on site now in Chak Shahzad, Islamabad, with 30,000 sq ft of approved covered area. Every quotation is built from the architectural, structural and MEP drawings, the soil report and a measured bill of quantities. An Avenir architect checks the work against those drawings at each stage, alongside the authority’s own inspections.

Scale
Close to four 1 Kanal houses under one roof
Covered area sets the quantities, and the quantities set the price. The table uses the DHA Lahore Construction and Development Regulations, 2026 edition, the one rulebook with a published footprint rule for a 4 Kanal house. Porches are excluded throughout.
- 1 Kanal7,869 sq ft
- 2 Kanal16,644 sq ft
- 4 Kanal31,825 sq ft
| 1 Kanal, 50 × 90 ft | 2 Kanal, 100 × 90 ft | 4 Kanal, 200 × 90 ft (two 2 Kanal joined) | |
|---|---|---|---|
| Ground floor | 2,703 sq ft | 5,879 sq ft | 11,340 sq ft (63% cap) |
| First floor | 2,163 sq ft (80%) | 4,586 sq ft (78%) | 8,845 sq ft (78%) |
| Stair mumty | 300 sq ft | 300 sq ft | 300 sq ft |
| Above ground | 5,166 sq ft | 10,765 sq ft | 20,485 sq ft |
| Basement, up to | 2,703 sq ft | 5,879 sq ft | 11,340 sq ft |
| Total with basement | 7,869 sq ft | 16,644 sq ft | 31,825 sq ft |
Ground floors of 1 and 2 Kanal from the clear spaces in Regulation 22(a); 4 Kanal from the 63% cap in Regulation 8(a)(3). First floor under Regulation 27(a)(3), mumty under Regulation 33(a), basement under Regulations 27(a)(1) and 35(a), less the porch. Compare 1 Kanal house construction and 2 Kanal house construction.
The multiple holds on site as well as on paper. Roughly four times the floor area means roughly four times the slab, brickwork, wiring and finishing, carried by one structure and built on one programme.
Other routes to 4 Kanal change the arithmetic: two plots combined in DHA Islamabad or DHA Rawalpindi, a 2,000 sq yd plot on CDA-regulated land, or an older non-standard plot in an established part of Lahore. Each has its own covered-area rule, set out on our 4 Kanal house design page. This page is for houses of roughly 18,000 to 30,000 sq ft of covered area, on any of those routes or on a larger plot.
A 4 Kanal plot inside a farmhouse scheme is a different project. Farmhouse schemes set their own covered-area limits, so the same land can carry a much smaller house, and farmhouse construction has its own page.

The basement
The basement is a building of its own
At up to 11,340 sq ft, the basement of a joined DHA Lahore 4 Kanal house is larger than everything a 2 Kanal house on a 100 × 90 ft plot can build above ground, about 10,765 sq ft. It is also the part of the house contractors most often price from a rate card before anyone has seen a soil report.
The regulations fix its outline. The soil decides how hard it is to build.
Basement of a joined 4 Kanal house, up to
11,340 sq ft
Everything a 2 Kanal house on 100 × 90 ft builds above ground
10,765 sq ft
What the regulations fix
- One storey only, with a ceiling height between 9 and 14 ft (Regulations 32(c) and 35(a))
- Excavation no deeper than 12 ft below the crown of the road (Regulation 32(c))
- 5 ft clear of a dead wall where one exists (Regulation 27(a)(1))
- An original soil investigation report with the submission, valid for one year (Regulation 14(p))
What it adds that no floor above needs
- Removal of about 136,000 cu ft of soil for the footprint alone, before working space
- Support to the sides of the excavation, designed by the structural engineer from the soil report, so neighbouring foundations are not undermined
- Dewatering, if the report finds groundwater within the excavation depth
- Retaining walls, and the raft or footings that carry them
- Waterproofing as one continuous system, detailed before the first concrete is poured
- A sump and pumps, drainage, mechanical ventilation and light wells
We price the basement from its own quantities, never as a share of the house rate. A single rate spread across basement and floors hides the most expensive square feet in the house inside an average.
In Islamabad and Rawalpindi the retaining walls and the frame are designed for seismic Zone 2B, one band above Lahore’s Zone 2A (Building Code of Pakistan Seismic Provisions 2007, Table 2.2).
On site
What a 20,000 sq ft structure asks of the site
The drawings settle these. The site team has to deliver them in the right order, before the next pour covers any mistake.
Slabs in bays
A ground floor slab of 11,340 sq ft is not cast in one day. It goes down in planned bays, with construction joints where the structural engineer places them, and each bay is checked before concrete is ordered.
Seismic zone
Lahore sits in seismic Zone 2A, Islamabad and Rawalpindi in Zone 2B (BCP SP-2007, Table 2.2). The zone changes the steel detailing. On CDA-regulated land, the architect certifies Form D at every slab level before the pour (ICT clause 5.5).
The lift shaft
The shaft is concrete and rises with the frame, so the lift is chosen before the ground floor slab is cast. Its internal size comes from the supplier’s drawing, not from a standard dimension.
Sleeves before concrete
Air-conditioning pipework, drainage and cable routes cross beams that cannot be cut once cast. Sleeves go in before each pour, taken from coordinated MEP drawings.
Backup power
DHA Lahore caps a house generator at 25 KVA (Regulation 58(a)(7)), well short of a 20,000 sq ft house at full load. So backup is designed: which circuits stay live, and where the solar panels and batteries go, with panels held within the 10 ft roof limit (Regulation 67).
Fire detection
The 2026 edition publishes a detector schedule only up to 2 Kanal (Annex C), so the 4 Kanal layout is settled at scrutiny. Detectors are hardwired, in fire-resistant cable and separate conduits, which have to be in the walls before plaster.
Cost
What a 4 Kanal house costs to build, and how it is priced
PKR 1,800 to 7,500
Published 2026 grey structure rates per sq ft from Lahore and Islamabad builders, for work described in almost identical words. At 20,000 sq ft, every PKR 500 of that spread is PKR 1 crore.
The difference is rarely the cement brand. It is the quantity of steel and concrete the drawings call for, and the workmanship that puts it in place. Rates quoted before the drawings exist also tend to leave out lines a house this size cannot do without: the boundary wall, the gate columns, the tanks and the parapets, which are then priced separately once the contract is signed.
| Lahore | Islamabad and Rawalpindi | |
|---|---|---|
| Complete house, Standard | PKR 7,500 per sq ft | PKR 7,900 per sq ft |
| Grey structure only | PKR 3,300 per sq ft | PKR 3,500 per sq ft |
| Complete house, Luxury | PKR 13,450 per sq ft | See the cost guide |
Source: our house construction cost guide, the single rate file used across this site. Its rates are set at a 1 Kanal house. The guide publishes a size adjustment for 2 Kanal, 1.04 on grey structure and 1.05 on finishing, and a 4 Kanal house carries a size adjustment as well, because spans, section sizes and the basement grow with the building.
Three things move the budget far more than the plot does. First, how much of the envelope you build: above ground only, or the basement too. Specification comes next, and the gap between Standard and Luxury is almost PKR 6,000 per sq ft. Last is everything priced outside the building, from 580 ft of boundary wall to the pool.
So we do not quote a 4 Kanal house from a rate card. The quotation follows the architectural, structural and MEP drawings, the soil report and a measured BOQ, and it arrives as one figure with the water tanks, boundary wall, gate columns and parapets inside it. Until the drawings exist, the construction cost calculator will run your own covered area and specification.
Next step
Four details are enough to size the budget
We will come back with the covered area your plot allows and what it plans at.
- The society and phase
- The plot dimensions
- Basement or not
- The finish level you have in mind

Scope
Inside the construction contract, and outside it
Both lists are part of the quotation, in writing, before you sign. On a house this size the exclusions are worth reading twice: each one is a budget line you carry yourself.
Inside the construction contract
- Setting out, excavation and the basement, with its waterproofing
- The complete structure: foundations, frame, slabs, masonry and plaster
- Plumbing, drainage, electrical work and fire detection, to the approved MEP drawings
- The underground and overhead water tanks, and a septic tank where the authority requires one
- Boundary wall, gate columns and parapet walls
- Finishing to the agreed schedule of finishes, on a complete-construction contract
Outside it: check for these four
Every Avenir quotation lists its own exclusions, because they follow your drawings. On a 4 Kanal house, look for these four, one way or the other.
- Authority fees, challans and utility connection charges
- Interior design, loose furniture and soft furnishings
- The soil investigation, commissioned from a testing firm before design
- Pool equipment and planting
Anything not listed in the signed BOQ is outside the contract.
Grey structure only is available at this scale too. On a 4 Kanal house it hands you the hardest coordination: the lift, the air-conditioning, the stone and the finishing trades all arrive after the contractor who built the frame has left the site.
Programme
The build, stage by stage, against the authority’s clock
Construction runs on two timetables. Ours is set by the drawings and the specification. The authority’s is set by its regulations, and it does not stop for procurement.
18 to 24 months
A typical 4 Kanal house takes 18 to 24 months to build. In DHA Lahore the house is expected to be complete within two years of approval (Regulation 17), and that clock starts at approval, not at site start. At the top of the range there is no slack unless work begins soon after the drawings are approved.
Our stages
Stage 1
Mobilisation
Hoarding, setting out and site services.
Stage 2
Basement
Excavation, support, waterproofing, retaining walls and the basement slab.
Stage 3
Frame
Ground floor to roof, slab by slab, with MEP sleeves in place before each pour.
Stage 4
Envelope and services
Masonry, plaster, windows, roofing, the lift and MEP first fix.
Stage 5
Finishing
Stone, joinery, ceilings, sanitary ware, final fix and commissioning.
Stage 6
External works and handover
Boundary wall, driveway, landscape, pool and snagging.
The authority’s checks
DHA Lahore, Regulation 18
- Layout complete, before work starts
- Main building at DPC level
- First floor structure, 1 ft above the ground floor roof slab
- Grey structure complete
- Final completion, when the sewer connection is opened
CDA, ICT Building Control Regulations 2020
- Form D at plinth and DPC, certified by the architect, before work continues (clauses 3.12.4 and 5.5)
- Form D at every slab level, before concrete is poured (clause 5.5)
- Architect inspections at up to nine stages, each reported within seven days (clause 3.12.8)
- Completion certificate before occupation (clause 2.8.1)
DHA Lahore drawings are valid for two years, and the house is expected to be complete within two years of approval (Regulation 17(b) and (c)). DHA Islamabad and Rawalpindi expect construction to start within three months and finish within three years (Regulations 8.9 and 8.31.1). A CDA approval lasts five years (clause 2.2.5). In DHA Lahore the completion certificate is normally issued within 20 days where no violation is found (Regulation 48); on CDA-regulated land, occupying a house without one carries a fine of PKR 50,000 a year (clause 2.8.1).
Order the lift, the window system and the stone before the frame is finished. On a house this size, those items often decide the handover date more than the concrete does.

Supervision
Who checks the work, and why it should be the architect
Passing a DHA stage verification means the work complies. It does not mean the work is good.
The DHA Lahore regulations say so themselves: supervision and quality assurance stay with the owner and the architects and engineers the owner appoints (Regulation 45). The authority checks compliance at five points. Everything between those points is yours to police.
Almost nobody builds a second house of this size. With no repeat customer to keep a contractor honest, the protection has to sit inside the contract and on the site. We run construction with the architect in charge of checking it, because the person who knows the drawings best is the one who can confirm that the steel and the levels match them before each stage is covered.
Clients expect the difference between contractors to show in material brands. The difference that decides the house is in quantities and workmanship: how much steel is in the beam, how true the wall is, how the waterproofing laps. Those are drawing questions, and they are answered on site.
If you live abroad
The plot decides the service, not your address. A client in London with a 4 Kanal plot in DHA Lahore is a full construction client, with every approval and variation recorded in writing so it can be made across time zones. We take construction contracts only where we can supervise the site through the working week: Lahore, Islamabad and Rawalpindi.
If another architect drew it
We build from another architect’s drawings when the set is complete and approved. If something is missing, we say what before pricing, because a quotation built on a partial set is the one that grows later. For one appointment covering design and construction, see Design + Build.
Before you sign
Before you sign: ten questions for any contractor bidding on a 4 Kanal house
The answers separate a firm that has built at this scale from one that will learn on your plot. Ask them of us too. We answer in writing.
Which houses above 15,000 sq ft of covered area have you built, and can I visit one?
A good answer: A named project, its covered area, and whether the firm built it or only designed it.
Is the quotation built from a measured BOQ, or from a rate per sq ft?
A good answer: A BOQ measured from the architectural, structural and MEP drawings, with the soil report behind the foundations.
What sits outside the rate?
A good answer: A written list. The boundary wall, gate columns, tanks and parapets should be inside the figure or named as extras.
How is the basement priced?
A good answer: From its own quantities: excavation volume, support to the excavation, retaining walls, waterproofing and pumps.
Who checks the work against the drawings, and when?
A good answer: A named person, at every authority stage and before every pour.
Who books the authority inspections?
A good answer: The contractor or the architect, named in the contract, for each DHA stage verification or CDA Form D.
How are steel and concrete checked on site?
A good answer: Bar bending schedules checked against the structural drawings, and test cubes taken from each pour.
How are variations priced and approved?
A good answer: In writing, priced before the work is done, and signed by you.
How are payments tied to progress?
A good answer: To measured work at defined stages, not to dates on a calendar.
How will you report to me if I am abroad?
A good answer: Every decision and variation recorded in writing, so nothing depends on a phone call.
Questions
Questions about building a 4 Kanal house
How much does it cost to build a 4 Kanal house?
It depends on how much of the envelope you build and on the finish, and at this size both move the budget by crores. Our construction cost guide publishes planning rates of PKR 7,500 per sq ft for a complete house at Standard specification in Lahore and PKR 7,900 in Islamabad and Rawalpindi, as at September 2026. Those rates are set at a 1 Kanal house, and a 4 Kanal house carries a size adjustment on top. A quotation follows the drawings, the soil report and a measured BOQ.
What is the covered area of a 4 Kanal house in DHA Lahore?
On two 2 Kanal plots joined side by side, the ground floor may cover 63% of 18,000 sq ft, which is 11,340 sq ft (Regulation 8(a)(3)), and the first floor 78% of that, about 8,845 sq ft. With a 300 sq ft stair mumty the house has about 20,485 sq ft above ground. A single basement of up to 11,340 sq ft, less the porch, takes the total to about 31,800 sq ft.
How long does it take to build a 4 Kanal house?
A typical 4 Kanal house takes 18 to 24 months to build. In DHA Lahore the house is expected to be complete within two years of approval (Regulation 17), so a 24 month build leaves no slack unless work starts soon after approval. DHA Islamabad and Rawalpindi allow three years (Regulation 8.31.1). Long-lead items such as the lift, the window system and the stone often decide the handover date.
How much does a basement add to a 4 Kanal house?
Up to 11,340 sq ft of floor, less the porch, and about 136,000 cu ft of excavation for its footprint at the 12 ft depth DHA Lahore allows (Regulation 32(c)). It is priced from its own quantities, including excavation support, retaining walls, waterproofing and pumps, because the basement carries costs the floors above it do not.
Is a 4 Kanal house just a 2 Kanal house built twice?
No. It is one structure, so the slabs are poured in bays, the frame and lift shaft rise together, and the services carry loads a smaller house never sees. In DHA Lahore the standby generator is still capped at 25 KVA (Regulation 58(a)(7)), so backup power has to be designed rather than bought.
Can I build a 4 Kanal house in DHA Lahore?
Yes, but not on a standard allotment. The 2026 edition makes 2 Kanal the largest standard residential plot (Regulation 4(a)), so a 4 Kanal house is built on two 2 Kanal plots joined side by side under Regulation 8, at the discretion of DHA, or on an older non-standard plot.
What inspections happen while a house is built in DHA Lahore?
Five stage verifications under Regulation 18: the layout before work starts, the main building at DPC level, the first floor structure, the completed grey structure, and final completion when the sewer connection is opened. The completion certificate is normally issued within 20 days where no violation is found (Regulation 48).
What is different about building a 4 Kanal house in Islamabad?
On CDA-regulated land, no septic tank is allowed on any plot (clause 4.1.10), rainwater harvesting is required from 400 sq yd (clause 4.1.2), and the architect certifies Form D at every slab level before the pour (clause 5.5). Islamabad and Rawalpindi also sit in seismic Zone 2B, one band above Lahore. DHA Islamabad and private schemes have their own rules, which are checked for each plot.
Can I move in before the completion certificate is issued?
On CDA-regulated land in Islamabad, no. Occupying a residential building without a completion certificate carries a fine of PKR 50,000 a year (clause 2.8.1, ICT Building Control Regulations 2020). In DHA Lahore the certificate follows the final stage verification.
Do you build 4 Kanal farmhouses?
Yes, as farmhouse construction. Farmhouse schemes set their own covered-area limits, so the same 4 Kanal of land usually carries a much smaller house, and the work centres on the land as much as the building. Our farmhouse construction page covers it.
Will you build from drawings made by another architect?
Yes, if the set is complete and approved: architectural, structural and MEP drawings. If something is missing we say what before pricing, because a quotation built on a partial set is the one that grows later.
Why do contractors quote such different rates for a 4 Kanal house?
Published 2026 grey structure rates from Lahore and Islamabad builders run from about PKR 1,800 to PKR 7,500 per sq ft, for work described in almost identical words. The difference is the quantity of steel and concrete and the workmanship, not the cement brand. A rate given before the drawings exist also tends to leave out the boundary wall, gate columns, tanks and parapets, which are then priced separately. At 20,000 sq ft, a PKR 500 difference in the rate is PKR 1 crore.
