Home Extensions in Surrey
More space, more light, more home — without the upheaval of moving. Designed and built by one team across Weybridge and the surrounding towns.
Home extensions
Room to breathe, built to last
A well-built extension is the most cost-effective way to get the home you want from the one you already love. Whether it's a kitchen-diner that finally fits the family, a double-storey addition or a bright garden room, Peter & Marcus and the team handle everything — drawings, Building Regulations, groundwork, trades and finish.
One team on site from start to finish, a clear quote up front, and work that's finished properly. That's how we've built our name across Surrey.



Extensions we build
Whatever shape your home and plot take, there's an extension that fits.
Single-storey extensions
Rear and side extensions that open up the ground floor — bigger kitchens, dining rooms and family spaces.
Double-storey extensions
Add a room below and a bedroom or en-suite above, in one efficient build.
Side-return extensions
Reclaim that narrow alley beside the house to widen a galley kitchen into a proper living space.
Wrap-around extensions
Combine rear and side return for a transformative open-plan ground floor.
Kitchen extensions
Light-filled kitchen-diners with bi-folds, roof lanterns and underfloor heating.
Garden rooms & orangeries
A bright, year-round room that connects the house to the garden.

Recent extension
A vaulted, light-filled addition
A rear extension opened into a bright, vaulted space with exposed beams and glazing onto the garden — a tired back of the house turned into the room everyone lives in.

Your questions, answered
Do I need planning permission for an extension?
Many single-storey extensions fall under permitted development, so they don't need full planning permission. We'll tell you exactly where you stand at the first visit and handle any applications and Building Regulations for you.
How long does a house extension take?
A typical single-storey extension takes around 8–12 weeks on site; larger or double-storey projects longer. We give you a clear programme with your quote.
How much does an extension cost?
It depends on the size, spec and finish — there's no one-size figure. We provide a clear, itemised quote after a free site visit, with no vague day rates and no surprises later.
Can I stay in my home during the build?
In most cases, yes. We seal off the work area, keep the site tidy, and plan the disruptive stages around you wherever we can.
