PKR

Per sq ft for the structure: foundations, frame, walls, roof, plumbing and wiring pipes. Use your contractor's current quote; this default is only an example.

PKR

Per sq ft for tiles, doors, windows, kitchen, bathrooms, paint and fittings. It varies hugely with the quality you choose.

For price rises and surprises. 10% is a sensible minimum.

How it's worked out

Cost = covered area × (grey rate + finishing rate) × (1 + contingency)

Worked example

A 2,250 sq ft house at Rs 3,000 a square foot for grey structure and Rs 2,500 for finishing costs Rs 12,375,000. With 10% contingency, budget Rs 13,612,500, or Rs 6,050 a square foot all-in.

The default rates are examples only. Ask two or three contractors for current written quotes in your city.

Questions people ask

What is grey structure?

The bare building: foundations, columns and beams, walls, roof, and pipes and conduits for plumbing and electrics. Finishing adds tiles, doors, windows, kitchens, bathrooms, paint and fittings.

How is construction cost per square foot worked out?

Multiply the covered area of all floors by the rate per square foot for grey structure and for finishing, then add a contingency.

How much contingency should I keep?

At least 10%. Steel and cement prices change, and almost every build finds something unexpected.
