At PKR 3,000–3,500 per square foot for a standard build, grey structure cost in Karachi accounts for 40–45% of your total construction budget, yet it is the stage most owners understand least. Many clients budget carefully for the grey structure phase and then discover that finishing work costs nearly as much again. Knowing exactly what grey structure includes, and what it does not, prevents expensive mid-project surprises. This guide covers current Karachi rates, a component-by-component cost breakdown, and a real case study so you can budget both phases from day one.
Grey Structure Costs in Karachi at a Glance
Grey structure rates in Karachi vary by specification and site conditions. Economy builds using standard local materials sit at the lower end. Premium builds using higher-grade steel, engineered concrete mixes, and imported additives push toward the upper range.
| Specification | Grey Structure (PKR/sq ft) | 5 Marla Total | 10 Marla Total | 1 Kanal Total |
|---|---|---|---|---|
| Economy | 2,500 – 3,000 | 4.2M – 5.0M | 7.0M – 8.4M | 14.0M – 16.8M |
| Standard | 3,000 – 3,500 | 5.0M – 5.9M | 8.4M – 9.8M | 16.8M – 19.6M |
| Premium | 3,500 – 4,500 | 5.9M – 7.6M | 9.8M – 12.6M | 19.6M – 25.2M |
Totals based on approximate covered built-up areas: 5 Marla ≈ 1,675 sq ft (double-story), 10 Marla ≈ 2,800 sq ft, 1 Kanal ≈ 5,600 sq ft. Actual costs vary by design, soil conditions, and foundation type.
These figures reflect rates from multiple Karachi-based contractors in early 2025 and are consistent with construction labour data published by Zameen.com. A standard grey structure per square foot Karachi 2025 cost sits comfortably in the PKR 3,000–3,500 range for most residential projects in areas like North Nazimabad, Gulshan-e-Iqbal, PECHS, and Bahadurabad.
What's Driving Grey Structure Costs in Karachi in 2025–2026
Four factors are pushing grey structure prices upward right now.
Steel prices and import dependency. Approximately 85% of Pakistan's steel production relies on imported billets and scrap (GJBMS, 2025). PKR depreciation passes through directly to rebar prices. Following Budget 2025–26 tariff rationalisation (reduction in Additional Customs Duties on inputs), steel rebar has eased from 2024 peaks. Grade 60 rebar currently runs PKR 228,000–242,000 per tonne in Karachi, down 10–15% from the PKR 240,000–270,000 range seen in early 2025. A grey structure for a 10-marla double-storey house typically consumes 12–18 tonnes of steel rebar. This is the single largest cost variable and will move with PKR/USD exchange rate.
Cement costs, pushed higher by Budget 2025–26 FED. The Federal Excise Duty on cement was doubled from PKR 2/kg to PKR 4/kg in the Federal Budget presented on June 10, 2025. DG Khan Cement formally notified the Pakistan Stock Exchange that this added PKR 125 per 50kg bag. Karachi cement prices, previously at PKR 1,390–1,450 per bag, are now PKR 1,520–1,560 per bag. A standard 10-marla grey structure requiring 90–120 tonnes of cement (1,800–2,400 bags) now carries PKR 225,000–300,000 in additional Federal Excise Duty versus a pre-budget estimate. Any quote using pre-July-2025 cement prices is underpriced.
Labour rate inflation. Skilled masons in Karachi charge PKR 2,500–3,500 per day in 2025. The State Bank of Pakistan's FY2025 Governor's Annual Report noted that while headline inflation averaged 4.49% for the full year, down sharply from 29.2% in FY2024, cumulative cost increases over two years remain embedded in contractor labour rates (SBP Governor's Annual Report, 2025).
Karachi-specific site conditions. High groundwater tables in low-lying areas, Clifton, parts of Bath Island, coastal Gulshan sectors, and some Scheme 33 localities, require deeper foundations or raft slab designs. These add PKR 150–300 per sq ft to foundation costs compared to stable, dry-soil plots in North Nazimabad or upper PECHS blocks.
According to the World Bank's Pakistan Housing Finance documentation, Pakistan faces a housing shortage of over 12 million units, with urban population growing at 3.76% annually, faster than the national average of 2.55%. This sustained demand keeps Karachi construction activity high and labour rates firm. (World Bank, Pakistan Housing Finance Project, 2024)
What a Grey Structure Actually Includes in Pakistan
"Grey structure" is a Pakistani construction term without a direct global equivalent. Internationally the closest terms are "shell and core" or "structural work only." In Pakistan, a grey structure handover covers every load-bearing and weather-enclosing element, but nothing decorative or finishing-grade.
This is where many owners searching for a grey structure estimate Karachi get confused. Some assume grey structure means the walls are plastered, the stairs are finished, and the roof is waterproofed. It does not mean any of these things unless specifically agreed in the contract.
Here is what is included:
Foundation
The foundation transfers every load the building places onto the soil. In Karachi, foundation type depends on a soil investigation. Stable areas like North Nazimabad and upper Gulshan blocks use strip or pad foundations. Coastal and low-lying areas often require a raft slab or pile foundation. Foundation work covers excavation, lean concrete (blinding layer), reinforced concrete footings, and a damp-proof course (DPC) to block rising moisture.
Structural Frame: Columns, Beams, and Slabs
Reinforced concrete columns and beams form the skeleton that walls hang on. Each floor level is completed with a concrete slab. This is the most engineering-critical phase, substandard column sizing, incorrect rebar placement, or weak concrete grade here creates structural risk that no finishing work can correct. For standard-spec Karachi builds, Grade 60 (420 MPa) deformed steel rebar is the minimum acceptable standard for columns and beams. Concrete for structural elements should reach 3,000 PSI compressive strength minimum; columns are often specified at 4,000 PSI.
Brick Masonry Walls
External and internal walls go up after the structural frame is in place. A standard 10 Marla house uses roughly 55,000–70,000 first-quality (Awwal grade) bricks, priced at PKR 18–20 per brick in Karachi markets. External walls are typically 9 inches (two-brick) thick; internal partitions are 4.5 inches (single-brick). A coarse plaster layer applied to wall surfaces is included in most Karachi grey structure contracts, but always confirm this in writing, as some contractors omit it.
Rough-in Plumbing and Electrical Conduits
Grey structure includes the initial plumbing pipe runs, underground drainage lines, vertical soil stacks, and underground water supply pipes. PVC electrical conduits are embedded in walls and slabs during construction, ready to accept wiring in the finishing phase. These rough-in services account for roughly PKR 200–350 per sq ft of the grey structure rate and are easy to overlook until the finishing contractor cannot find properly positioned conduits.
What a Grey Structure Does NOT Include
This is where budget overruns originate. The items below are always part of the finishing phase, billed separately from grey structure:
| Finishing Item | Included in Grey Structure? |
|---|---|
| Floor tiles and wall tiles | No |
| Interior and exterior paint | No |
| Bathroom fittings (WC, basin, taps, shower) | No |
| Kitchen cabinets and countertops | No |
| Electrical wiring, switches, sockets, DB board | No |
| Doors, frames, and ironmongery | No |
| Windows and glazing | No |
| False ceilings or cornices | No |
| Staircase railing and balustrades | No |
| External boundary wall | No (often, unless specified) |
| Waterproofing (roof and bathrooms) | Sometimes, confirm explicitly |
Finishing typically costs 55–65% of the total construction budget, roughly equal to or greater than the grey structure itself for a standard Karachi build.

How Naffees & Sons Handles Grey Structure Builds in Karachi
Naffees & Sons has been building in Karachi since 1972. Grey structure work is the foundation of every project we handle, residential builds in Gulshan and North Nazimabad, commercial shells in PECHS, and demolition-rebuilds in Clifton and Bahadurabad.
Our grey structure process starts with a site investigation visit before any contract is signed. We check soil conditions, groundwater depth, SBCA drawing approval status, and material delivery access. Foundation type is specified by our structural engineer after reviewing the site, not assumed from a generic template.
Over 50+ years we have established supplier relationships across every major material sourcing zone in Karachi: structural steel from Shershah and SITE Industrial Area, cement from trusted batch-supply relationships with the major brands, and aggregate from verified suppliers who deliver consistent grades. We know where to source each material at the best cost-to-quality ratio, which means our clients get the right materials without overpaying, and without the delays that come from dealing with unreliable suppliers.
During construction, a resident site engineer is assigned to every grey structure project. Concrete pours are supervised and documented. Steel placement is checked against structural drawings before every pour. We do not allow on-site drum mixing for structural elements, ready-mix or batch-plant concrete is used for all columns, beams, and slabs as standard practice.
A typical 10 Marla standard-spec grey structure in areas like North Nazimabad or Gulshan-e-Iqbal takes 4–6 months from foundation excavation to roof slab completion, weather and material availability permitting. Clients receive a milestone-based payment schedule tied to verified construction stages, not calendar dates.

Grey Structure vs. Full Turnkey Build: Cost Comparison
Understanding how grey structure cost sits within a total project budget helps owners plan financing and cash flow from day one.
| Plot Size | Grey Structure (Standard) | Full Turnkey (Standard) | Grey Structure % of Total |
|---|---|---|---|
| 5 Marla | PKR 5.0M – 5.9M | PKR 10.5M – 13.0M | ~46–48% |
| 10 Marla | PKR 8.4M – 9.8M | PKR 18.0M – 22.0M | ~44–46% |
| 1 Kanal | PKR 16.8M – 19.6M | PKR 36.0M – 46.0M | ~43–46% |
Full turnkey includes grey structure plus all finishing: tiles, paint, fixtures, doors, windows, kitchens, bathrooms, and electrical installation. Rates are for standard-spec builds in Karachi as of 2025.
Some owners take a grey structure handover and manage finishing work independently to control specification choices and spread costs over time. The trade-off is real: you gain flexibility but take on full project management, procurement, and trade coordination. A standard 10 Marla finish-out adds 4–8 more months before the house is liveable.
For owners building for rental income or resale, getting a grey structure estimate from Naffees & Sons includes a finishing cost projection so both phases are budgeted before a single brick is laid. Our construction guides also cover renovation, commercial builds, and location-specific cost breakdowns.
Real Costs: A Karachi Case Study
A homeowner in North Nazimabad Block J began a 10 Marla demolition-rebuild in mid-2024. The original single-story structure was demolished and a double-story replacement designed at 2,800 sq ft covered built-up area.
Grey structure budget breakdown at standard specification:
| Component | Estimated Cost (PKR) |
|---|---|
| Foundation (reinforced concrete strip footings + DPC) | 1,650,000 |
| Structural frame (columns, beams, floor and roof slabs) | 2,400,000 |
| Brick masonry, external and internal walls + base plaster | 1,850,000 |
| Rough-in plumbing and embedded electrical conduits | 700,000 |
| Labour, all trades across grey structure phase | 1,600,000 |
| Total grey structure | 8,200,000 |
Equates to PKR 2,929 per sq ft, within the standard-spec range. The complete finished house, including all tiles, paint, kitchen, bathrooms, doors, windows, and electrical fittings, was projected at PKR 18.5–20.0 million total.
On a demolition-rebuild specifically, the structure coming down is not only a cost. Reinforcement steel, timber from doors and roof trusses, aluminium and UPVC sections, and copper wiring from the old building all carry genuine scrap and salvage value. We assess what is recoverable before demolition starts, sell it into the scrap market ourselves rather than letting it leave with a demolition crew, and credit the realised value back against the client's project cost. It is a financial offset from a scrap sale, not a claim that old steel gets reused structurally in the new build, but on a demolition-heavy project it is worth raising with your contractor before the first wall comes down rather than after. Our demolition cost and scrap value guides cover current rates for both.
Frequently Asked Questions
What is the grey structure cost per square foot in Karachi in 2025?
Grey structure cost in Karachi ranges from PKR 2,500 to PKR 4,500 per square foot in 2025, depending on specification. Economy builds using standard local materials and simpler structural designs cost PKR 2,500–3,000 per sq ft. Standard-spec builds, the most common choice in Gulshan, North Nazimabad, PECHS, and Bahadurabad, run PKR 3,000–3,500 per sq ft. Premium specifications with higher-grade steel, engineered concrete, and deeper foundations push to PKR 3,500–4,500 per sq ft. A grey structure estimate from a site-visit contractor gives a more accurate number for your specific plot and design.
How long does grey structure construction take in Karachi?
Timeline depends on plot size and design. A 5 Marla grey structure typically runs 3–4 months from excavation to roof slab completion. A 10 Marla double-story takes 4–6 months. A 1 Kanal structure needs 6–9 months. Karachi's monsoon season (July–September) can delay concrete pours and masonry work by 2–4 weeks. Steel supply disruptions during periods of import restriction have also extended project timelines in recent years.
Beyond the weather and materials, Karachi's working calendar adds real-world gaps that experienced builders plan for: Friday is treated as a half or full day off by a significant portion of the labour workforce; Eid shutdowns result in 1–2 week work stoppages as workers travel home; and political strikes (hartals) can halt sites at any time. A professional builder builds a 15–20 day buffer into every phase timeline to absorb these disruptions. Any grey structure schedule with no contingency for Karachi's actual working culture is not a realistic programme. Always agree on a milestone-based schedule with your builder rather than a fixed calendar end date.
Do you need an SBCA permit before starting grey structure work in Karachi?
Yes, an approved building plan and No Objection Certificate (NOC) from the Sindh Building Control Authority (SBCA) is legally required before breaking ground on any residential construction in most of Karachi. The permit process involves submitting architectural and structural drawings, proof of site ownership, and applicable fees. SBCA review takes 4–8 weeks for a standard residential application. Building without a permit risks stop-work orders, demolition notices, fines, and complications when selling the property. If you need help understanding the SBCA application process, our team walks clients through permit requirements as part of our pre-construction planning.
What materials should a grey structure use in Karachi to meet safety standards?
For structural safety, grey structure columns, beams, and slabs should use Grade 60 (420 MPa yield strength) deformed steel rebar, not the cheaper Grade 40 still used in some economy builds. Cement should be OPC 43-grade or 53-grade from a reputable Pakistani manufacturer. Concrete mix design for structural elements should achieve a minimum compressive strength of 3,000 PSI (21 MPa) for slabs, with columns often specified at 4,000 PSI. Brick quality matters too, first-quality Awwal bricks should be used for external walls, not seconds or reject stock that absorbs more moisture. Always ask to see your structural engineer's mix design specifications before construction starts.
What is the difference between a grey structure and a full turnkey build in Pakistan?
Grey structure vs full construction Pakistan, the difference is the finishing. Grey structure is the load-bearing skeleton: foundation, structural frame, brick walls, rough plumbing, and electrical conduits. It covers roughly 40–46% of total project cost. Full turnkey adds everything that makes a building liveable: floor and wall tiles, paint, bathroom fittings, kitchen cabinets, electrical wiring and switches, doors, windows, and all ironmongery. A 10 Marla grey structure at PKR 8.4–9.8 million becomes an PKR 18–22 million turnkey project at standard specification. Some owners complete grey structure first and finish in phases as finances allow, a workable approach that extends the overall project duration by 4–8 months.
How do I evaluate a grey structure contractor in Karachi before signing a contract?
Ask to visit at least two completed grey structure projects, not photographs, actual sites. Verify that a licensed structural engineer is assigned to the project and will be on-site during all concrete pours, not just available by phone. Demand a written scope of work that specifies: concrete grade per element, steel grade and diameter for columns and beams, foundation type, wall thicknesses, whether plaster is included, and payment milestones tied to verified construction stages (not calendar dates). Reject any contractor who quotes a per-sq-ft rate without a site visit, grey structure cost varies significantly with soil conditions, foundation design, and structural complexity. Our full guide to how to choose a builder in Karachi covers the complete checklist.
