Home construction cost calculator

This is a fast first-pass estimate. After each answer, the next house stage appears so you can see where the budget grows.

Estimated build cost

Each window changes the total cost, but also the final standard of the house.

Cost grows in stages

We calculate the structure first, then the foundation, then heating, windows and buffer. That shows what is really pushing the cost up.

What the calculator estimates

It combines a base rate for a single-storey or two-storey house, foundation cost, heating, windows and a contingency buffer.

Why this is useful before quotes

Before you request contractor quotes, it helps to know whether the plan is realistic. After that, BuildIQ can track the real costs, invoices and changes.

Before talking to contractors, check

  • whether the chosen house type pushes the price too far
  • whether the foundation matches the plot and design
  • whether the heating system fits the plan
  • whether the number of windows makes a big difference
  • whether you have a buffer for surprises and changes
