Building your own home is one of the most exciting projects you can take on — but also one of the most detailed. Your architect is your guide from the very first sketch through to handing over the keys. Here's how each stage works and what you can expect in terms of costs.
How Architects Usually Charge
Architects for new build homes generally charge in one of two ways:
- 1.Percentage of the total build cost — typically 7–11% for a full service (from concept to completion).
- 2.Fixed fee per stage — agreed after the brief and size of the house are confirmed.
Additional costs such as structural engineering, planning, energy assessments, and Building Control are separate from the architect's fee.
