FAQs
Questions we're asked
Do I need an architect for an extension?
For work that changes your home's layout, adds an extension or alters the front elevation, you need drawings: for the planning application, for building regulations, and for a builder to price and build from. That's what this service is. Our lead architect, Ioanna, is ARB-registered and has worked on UK homes since 2006.
Do I need planning permission for a rear extension?
It depends on the size of the extension, whether the house is in a conservation area, and whether permitted development rights still apply. Private estate covenants can add a separate layer on top. We check the planning position alongside the deeds and any estate requirements before we draw anything.
How long does a planning application take?
About 8–10 weeks once the drawings are ready, then about 4–5 weeks more for the building regulations and technical package your builder prices from. From first measured survey to that full package, allow around four months.
Do you do loft conversions?
Yes. Loft and roof alterations sit alongside rear extensions and side returns, layout reconfigurations and changes to front elevations. Structural plans are prepared with our structural engineer.
Who arranges party wall matters?
You appoint the party wall surveyor, with our advice on what your project needs. We handle the planning application, the building regulations and technical drawing package, and appointing the structural engineer and building contractor.
