Common questions.
Everything you need to know about architects, planning and building in London.
London architects typically charge between 7–15% of the build cost for full services. At Hampstead Architects, we offer fixed-fee design stages so you know exactly what you'll pay before committing. A free initial consultation lets us scope your project precisely.
Many single-storey rear extensions in London fall under permitted development, but conservation areas, listed buildings and larger schemes almost always require a planning application. We assess your site at the consultation stage and advise on the fastest route to approval.
London boroughs typically determine householder planning applications in 8 weeks. With a well-prepared submission — strong drawings, clear design and access statement, and pre-application advice where useful — we maintain a 98% first-time success rate.
Yes. Hampstead Architects works across all 32 London boroughs, from Barnet to Bromley and Hammersmith to Hackney. Our deep familiarity with each local authority's design policies is one of the reasons we get planning through first time.
Absolutely. We offer end-to-end project management — from contractor tendering and selection to on-site oversight, snagging and final handover. You work with one architect throughout, ensuring design intent is preserved from concept to keys.
Permitted development rights allow certain extensions, loft conversions and outbuildings without full planning permission, subject to strict size and location rules. We'll confirm whether your project qualifies and prepare a Lawful Development Certificate to protect you on resale.
