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
