About the House Construction Cost Calculator

This calculator estimates the cost of building a house from its covered area and the per-square-foot rates you get from contractors. Enter the covered area per floor, the number of floors, the grey structure rate, the finishing rate, any fixed costs such as map approval and utility connections, and a contingency percentage. It shows the total estimated cost, the grey structure and finishing amounts, the contingency and an all-in cost per square foot.

It helps families planning a new home, people comparing contractor quotes, overseas Pakistanis building back home, and anyone deciding between a single and double storey. Construction prices in Pakistan change quickly with cement, steel, bricks, fuel and labour costs and differ by city and builder, so the calculator does not assume any rates. You enter current quotes, and the arithmetic stays on your device.

How is house construction cost estimated?

Most builders in Pakistan quote construction in two parts, priced per square foot of covered area. Grey structure is the basic building: excavation, foundation, columns, beams, brick walls, roof slabs, and usually electrical and plumbing pipes laid in the walls. Finishing is everything that makes it liveable: plaster, flooring, tiles, doors, windows, kitchen, bathroom fittings, wiring, paint and woodwork. Finishing quality varies enormously, which is why its rate varies more than the grey structure rate.

Covered area is the built-up floor area under a roof, measured for each floor and added together. A two-storey house on a 5 marla plot might have around 1,125 square feet per floor, giving 2,250 square feet in total; the exact figure depends on the plot size, approved plan and setbacks.

The estimate is: covered area × (grey rate + finishing rate) + fixed costs, plus a contingency for price rises and changes during construction. Fixed costs cover items not linked to area, such as plan approval fees, utility connections, a boundary wall or a gate, which are better entered as lump sums.

How to use the House Construction Cost Calculator

1. Enter the Covered area per floor in square feet from your architect’s plan or estimate.
2. Enter the Number of floors.
3. Enter the Grey structure rate per square foot quoted by contractors in your city.
4. Enter the Finishing rate per square foot for the quality you want. Leave it empty if you only need a grey structure estimate.
5. Add Fixed costs such as map approval, connections and boundary wall, and set a Contingency percentage (10% by default).
6. Read the total, the breakdown and the all-in cost per square foot. Use Copy result to share it with family or your contractor.

Change one rate at a time to see how much a different finishing quality or contractor quote changes the total.

Key features and benefits

• Two-part estimate. Grey structure and finishing priced separately, as most contractors quote them
• Multi-storey. Multiplies the per-floor covered area by the number of floors
• Fixed costs. Add approvals, connections and other lump sums
• Contingency. A percentage buffer for price rises and changes
• All-in rate. Total cost divided by covered area, for comparing quotes
• No assumed prices. Uses only the rates you enter, so estimates never rely on outdated prices
• Private. Runs in your browser

Practical examples

A double-storey house

Covered area 1,125 sq ft per floor on 2 floors is 2,250 sq ft. With a grey structure rate of Rs 3,000 and a finishing rate of Rs 2,500 per sq ft — illustrative rates, not current market prices — grey structure is Rs 6,750,000 and finishing Rs 5,625,000. A 10% contingency adds Rs 1,237,500, giving an estimated Rs 13,612,500, or about Rs 6,050 per square foot all-in.

Grey structure only

Leave the finishing rate empty to see the grey structure cost alone. This is useful when you plan to finish the house in stages as funds allow.

Comparing two contractors

Contractor A quotes a lower grey rate but excludes electrical piping; contractor B includes it. Add the missing items to A’s quote as a fixed cost so you compare the same scope, then compare the all-in rate per square foot.

Effect of finishing quality

On 2,250 sq ft, every Rs 500 difference in the finishing rate changes the total by Rs 1,125,000, before contingency. Finishing choices such as tiles, kitchen and bathroom fittings matter as much as the structure.

Single storey or double storey?

At the same illustrative rates, a single storey of 1,125 sq ft is estimated at Rs 6,806,250 including contingency, and a double storey of 2,250 sq ft at Rs 13,612,500. A simple per-square-foot model treats every floor the same. In practice the foundation and some roof work are shared, while the ground floor of a two-storey house may need a stronger structure, so ask your engineer and contractor how their rates change for each option before deciding.

Common use cases

• Families planning a new house set a realistic budget before buying materials or signing a contract.
• Overseas Pakistanis check contractor quotes for a house being built back home.
• Plot owners compare building now with building later, or single and double storey.
• Small builders prepare quick estimates for clients.
• Loan applicants estimate how much construction financing they need.

Accuracy, limitations and privacy

The calculation is exact for the inputs, but construction estimates depend heavily on the scope included in each rate. One contractor’s “grey structure” may include items that another leaves out, and finishing rates can differ several times over depending on materials. Prices for cement, steel and bricks can change significantly during a project, which is why a contingency is included.

The tool does not include structural design, soil conditions, basement costs, approval fees in your area or taxes unless you add them. Always get detailed, written quotes and have an engineer approve the structure. Nothing you enter is stored or sent.

• No construction rates are built in; results depend on the quotes you enter.
• Basements, extra-heavy foundations, solar, lifts and landscaping are not included unless added as fixed costs.
• Not a substitute for a detailed bill of quantities prepared by a professional.

Tips and best practices

• Ask every contractor for a written list of what their per-square-foot rate includes and excludes.
• Pay in stages linked to completed work, not large advances; the stage payment planner helps.
• Keep a contingency of at least 10% — material prices often rise during construction.
• Get the map approved before construction to avoid penalties or demolition orders.
• Buy major materials such as steel and cement from known suppliers and keep receipts.
