Stripe Architects is a credible alternative for some project types; get a quote from both and compare.
Stripe Architects operates as a London residential architecture practice. Which suits you depends on whether you want a defined drawing package at a known price or a broader service.
A London residential practice offering full architectural services on domestic projects.
Where that model is strong: Full-service architectural offer including interior and detailed design stages.
What to establish before you commit: A full-service offer is priced accordingly. If you only need planning and building regulations drawings, ask for that scope priced separately rather than as part of a full RIBA-stage appointment.
Every figure below is on our pricing page and does not change with the size of your build. We do not quote a percentage of build cost, because it gives a designer an interest in a larger build.
