Common questions
How much does an architect cost for an extension?
Planning drawings for an extension are typically £1,500–£4,000; a full RIBA service is usually 8–15% of the build cost.
Do I need an architect for planning permission?
Not always, but for extensions and conversions an architect or architectural technologist produces the drawings and manages the application.
What is the difference between drawings and full service?
A drawings-only package gets you planning/building-regs plans; full service adds tender, contractor selection and site oversight.
