Cost breakdown
Traditional architect fees
A RIBA-chartered architect typically charges 8–15% of the build cost for a full service (concept through to completion). For a £60,000 extension, that is £4,800–£9,000. This covers concept design, planning drawings, Building Regulations, tender documentation, and site visits during construction.
Architectural technologist fees
Architectural technologists (not architects, but qualified designers) typically charge 5–10% or fixed fees. They specialise in the technical side — planning drawings, Building Regulations, structural coordination. Many homeowners find this is all they need.
Fixed-price design services
Services like PlanBuildCo charge fixed fees for specific deliverables. Design discovery: £250. 3D laser scan: £650. Structural calculations: £350. Planning application: £2,200. Building Regulations: £399. You know the cost before you start, and you only buy what you need.
What to look for
Choose based on what you need. If you want a bespoke architectural vision and can afford 8–15%, hire an architect. If you want professional plans at a predictable cost, a fixed-price service delivers the same technical output for a fraction of the fee.
