Building and renovation in Frimley
Frimley sits a few minutes from our Farnborough base, spanning older village property around Frimley High Street, substantial inter-war housing, extensive post-war estates through Frimley Green and Mytchett, and newer development close to the hospital and the A325 corridor.
Work here is typically about layout rather than footprint: taking out a rear wall and carrying it on steel to make one connected kitchen and dining space, converting a garage that was only ever storing boxes, or extending to the rear where the garden depth allows.
The Blackwater valley and canal side of the area brings ground and water considerations that shape foundation and drainage design, so a proper survey is more than a formality here.
Frimley is a few minutes from our Farnborough base, effectively local to us.
What Frimley homeowners ask us for most
- Structural alterations and RSJ installation for open-plan ground floors
- Single-storey rear extensions
- Garage conversions
- Drainage repairs, new runs and diversions
- Patios, driveways and retaining landscaping
Covering GU16 and neighbouring GU15.

Services in Frimley
Building services available in Frimley
Structure, groundworks, drainage and finish are all handled in-house, so a single team carries your project from the first excavation through to the final finish.

Extensions in Frimley
More usable ground-floor space in the home you already own, priced before we start, built by one experienced crew, and handed back with building control sign-off and an insurance-backed guarantee.

House Refurbishments in Frimley
One contractor for the strip-out, the structure, the services and the finish, priced in full before we start, sequenced so trades are not tripping over each other, and guaranteed when it is done.

Garden Rooms in Frimley
A properly built room at the end of the garden, insulated, powered, heated and usable in February, for a fraction of the disruption of extending the house.

Loft Conversions in Frimley
A bedroom, bathroom or office in space you already own and already heat, with the structure, stair and escape route designed to pass building control rather than to look finished.

Garage Conversions in Frimley
The walls and roof are already there, which makes a garage the fastest extra room in most houses, provided the floor, damp and insulation are done properly rather than boarded over.

Hard Landscaping in Frimley
Outdoor surfaces that stay flat, drain where they should and still look right in ten years, because the sub-base, falls and edge restraints are built correctly under the part you can see.

Groundworks in Frimley
The part of the build nobody sees and everything else depends on, excavated to the right depth for the ground you actually have, inspected before it is covered, and priced before we dig.

Drains in Frimley
Drainage that is set to the right fall, tested before it is covered and recorded on the completion paperwork, whether it is a diversion under a new extension or a failed run being replaced.

Structural Alterations in Frimley
Walls removed and openings formed the way an engineer designed them: temporary support first, load path carried all the way to the ground, and inspected before it disappears behind plaster.

RSJ Installation in Frimley
The beam is the easy part. Getting the calculation, the temporary support, the bearings and the load transfer right is what keeps the structure above it exactly where it was.
Property types
Property types across Frimley
Older village property
Solid walls and shallow footings near the High Street. Extensions need deeper new foundations and careful connection to existing structure.
Inter-war housing
Good roof pitches and standard rear layouts: dormer lofts and single-storey rear extensions with steelwork are the norm.
Post-war estates, Frimley Green and Mytchett
Shallow foundations, attached garages, ageing drainage. Garage conversions and extensions are common, with drainage diversions frequently required.
Modern housing near the hospital
Tighter plots and trussed roofs, favouring internal structural alterations and garden rooms.
Why choose Urban Build in Frimley
How we work in Frimley
A team you can name
A core team of around five experienced tradespeople, with trusted subcontractors only where a job needs them. The person who surveys your Frimley property is part of the team that builds it.
Fixed price before we start
The price is agreed before work begins. It changes only if you ask us to change the scope, not because something predictable was left out of the quote.
Itemised quote in 21 days
A full itemised quote, typically around ten pages for an extension, costs £500 and arrives within 21 days. That £500 is deducted from the final price if the job goes ahead.
Insured work
Public liability and contractors insurance are in place on every project we run.
Insurance-backed guarantee
Completed work is covered by an insurance-backed guarantee, so the cover does not depend on us still being around.
Staged payments
Payments are tied to progress on site. You are never funding a Frimley project months ahead of the work.
We do not publish job counts or years-in-business figures we cannot evidence. If you want to see work, ask and we will talk you through comparable projects: see our work.
Local conditions
Common building considerations in Frimley
These are the details a thorough survey settles before a price is agreed. We survey for all of them before we price.
Ground water near the Blackwater and canal
Low-lying ground holds water, which affects excavation, foundation type and how surface water has to be managed. It is a design input, not bad luck.
Ageing estate drainage under new work
Post-war runs often need repair or diversion before an extension or new hardstanding goes over them.
Removing walls without proper support
Open-plan layouts need engineered beams, correct padstones and proper temporary propping. Getting these details right is what keeps ceilings level and plaster sound years later.
Shallow original footings
New foundations next to shallow existing ones require greater depth and correct sequencing, surveyed and priced up front.
