Payment is typically staged throughout the project. Expect to pay 10-20% upfront, with remaining fees spread across project milestones and completion stages.

What’s included in a full architectural service?
Full service includes concept design, planning applications, technical drawings, building regulations approval, contractor selection, and construction monitoring.
How do I choose the right architect?
Look for RIBA chartered architects with relevant project experience. Check portfolios, references, and fee structures. Meet multiple architects before deciding.
Can I reduce architect fees?
Yes, by limiting scope to design only, providing clear briefs, minimising changes, and taking on some project management responsibilities yourself.
