Built to Last
North Bristol Conversions is a local, FMB-accredited team building timber frame extensions across north Bristol and the surrounding areas. We’re not a call centre for subcontractors — we’re the same faces on site from first survey to final fix.
We’ve built our reputation on doing things properly: honest quotes, tidy sites, and extensions that look like they’ve always belonged to the house. Timber frame is our specialism because it lets us build fast without cutting corners — precision-engineered off-site, then assembled quickly and weathertight on yours.
Every project is designed around how you actually live, not a one-size-fits-all template. That’s why homeowners across Bristol keep recommending us to their neighbours.
Room to Extend
Four Ways to Extend Your Home
Timber frame extensions can be shaped to fit almost any home. Here are four of the most popular routes:
Single-Storey Rear Extension
The classic way to open up a kitchen or living space, extending straight out into the garden.
Side Return Extension
Reclaims that awkward side alley running alongside terraced and semi-detached homes — often transforming a galley kitchen into a bright, sociable space.
Wrap-Around Extension
Combines a rear and side return extension into one continuous space, ideal for open-plan kitchen-diners.
Two-Storey Extension
Adds space both upstairs and down — a bedroom or bathroom above, extra living space below — for maximum square footage in one build.
Common Questions
Timber Frame Extensions FAQs
Do I need planning permission for a timber frame extension?
Many single-storey extensions fall under Permitted Development and don’t need full planning permission, though this depends on your property, its size and any previous extensions. We check this for you as part of the free survey.
How long does a timber frame extension take to build?
Because the frame is manufactured off-site and arrives ready to assemble, timber frame extensions are typically faster to build than traditional brick construction — often shaving weeks off the programme.
Are timber frame extensions as durable as brick?
Yes. Built and insulated correctly, a timber frame extension is just as durable and long-lasting as a masonry one, with the added benefit of excellent thermal performance.
Will it disrupt my home while it's being built?
We plan the build sequence to minimise disruption, and because so much of the frame is prefabricated, the on-site assembly phase is quicker than conventional builds.
How much does a timber frame extension cost?
Costs vary depending on size, finish and site access. We provide a fixed-price quote after your free survey, so there are no surprises later.
