What it is
Garden Rooms: what the work involves
A garden room gives you a separate space without touching the house: an office away from the kitchen table, a gym you will actually use because it is thirty seconds from the back door, a studio, a treatment room or a teenager's retreat.
The difference between a garden room and a summerhouse is what you cannot see. Ours are built on a proper base with an insulated floor, wall and roof build-up, breather and vapour control layers, and electrics run and tested so the space works in winter as well as June.
Ballpark figures are free. A full itemised quote is £500, deducted from the final price if the job goes ahead, so you can compare a specification rather than a headline price.
Who it is for
- Home workers who need a door that closes and a call that is not interrupted
- Anyone who wants a gym, studio or workshop without losing a bedroom
- Families needing extra space where a house extension is not practical or affordable
- Owners of small home businesses wanting a client-facing room off the house
When it is needed
- Working from home has taken over a bedroom or the dining table permanently
- You want usable space without the disruption of building onto the house
- An old shed, summerhouse or lean-to is rotten and wasting a good part of the garden
- The house has no spare room left but the garden has room to spare
What goes wrong
Why specification and detailing matter
These are the failures that come back to us as remedial work. Every one of them is cheaper to avoid at quote stage than to correct after the finishes are on.
A base that moves
Rooms built on paving slabs or an undersized slab settle unevenly. Doors bind, the roof line goes out and the internal finish cracks, and correcting a base under a finished building means dismantling it.
Cold, damp and unusable half the year
Thin walls, no vapour control and a single-glazed door produce condensation, mould on stored belongings and a room you stop using in November. Insulation and ventilation have to be designed together.
Extension leads instead of a proper supply
Running a garden room off a lead through a window is a fire and shock risk and cannot carry a heater. A buried armoured supply, correctly protected and tested, is the only sensible answer.
Ignoring size and siting rules
Height, boundary distance and how the room will be used all affect whether it stays within permitted development. Getting that wrong after the build is a costly problem to unwind.
How it works
Our process, from first call to handover
Site visit and siting
We look at levels, access, drainage, trees and where the sun lands, and talk through what the room is for before deciding its size and position.
Itemised fixed quote
A fixed-price quote within 21 days covering base, structure, insulation, glazing, electrics, heating and finishes, with exclusions listed.
Base and structure
Groundworks and an engineered slab or pad-and-beam base, then the frame, sheathing, breather membrane and roof to a watertight shell.
Insulation, power and fit-out
Insulated floor, wall and roof build-up, vapour control, buried armoured supply, sockets, lighting and heating, then internal linings and decoration.
Test, snag and guarantee
Electrical testing and certification, snags cleared, ground made good around the building, and the work covered by an insurance-backed guarantee.
What you get
The benefits of garden rooms
Usable in every month
Insulation, glazing and heating specified for winter use, not just summer occupancy.
No disruption indoors
Almost all the work happens outside, so the house stays normal while the room goes up.
Separation that works
A short walk and a door that closes does more for concentration than any corner of a bedroom.
Cheaper than losing a room
You keep the bedroom, and you keep the option of returning the garden to garden later.
Safe, tested electrics
A proper buried supply with certification, sized for heating and equipment rather than a laptop.
Built and guaranteed
Insurance-backed guarantee on the completed work, with insurance in place during the build.
In detail
Garden Rooms: methods, materials and variations
Uses and variations
Most garden rooms we build fall into four uses: office, gym, studio or hobby room, and garden lounge, and the use changes the specification more than the appearance does. A gym needs a stiffer floor build-up and better ventilation; an office needs data and glare control; a studio may want a north-facing roof light.
Rooms with a shower or WC bring drainage into scope, which means either a gravity connection to the existing run or a pumped solution, and that is worth settling at quote stage.
- Garden offices with data and glare control
- Gyms with reinforced, resilient floor build-ups
- Studios, therapy and treatment rooms
- Garden lounges and bar rooms
- Rooms with a shower or WC where drainage allows
Materials and construction
Structure is normally a treated timber frame on an engineered base, sheathed and wrapped in a breather membrane, with mineral wool or rigid insulation in floor, walls and roof and a vapour control layer on the warm side. Roofs are warm-deck flat with EPDM, GRP or single-ply, or a shallow pitch where planning height allows.
External finishes are usually cedar, thermally treated timber or composite cladding chosen for how much maintenance you want to do. Internally, plasterboard and skim gives a room that reads as part of the house rather than a shed.
- Treated timber frame, engineered slab or pad-and-beam base
- Mineral wool and rigid PIR insulation with vapour control
- EPDM, GRP and single-ply warm-deck roofs
- Cedar, thermo-treated timber and composite cladding
- Aluminium or uPVC sliding and French door sets
- Buried SWA supply, RCD protection, tested and certified
Siting, access and neighbours
Access decides cost more often than size. Where a machine cannot reach the back garden, muck and materials move by barrow through a side gate, and that is priced honestly rather than discovered later.
Position also affects the trees you keep, the drain runs you cross and the boundary distance that governs both fire spread requirements and permitted development. We raise all of that at the site visit.

Questions
Garden Rooms questions we are asked most
How much does a garden room cost?+
It depends on size, insulation and glazing specification, whether drainage is involved and how difficult access is. Ballpark figures are free after a site visit, and a full itemised quote is £500, deducted from the final price if the job goes ahead.
Do I need planning permission?+
Many garden rooms fall under permitted development, but height, boundary distance, proportion of garden covered and intended use all affect it. We flag anything that looks like it needs an application, and planning submissions are made by you or your architect while we handle building control where it applies.
Can it be used all year round?+
Yes, that is the point of the build-up we use. Insulated floor, walls and roof, vapour control, proper glazing and a heating provision sized for the room.
Will it have power and heating?+
Yes. A buried armoured supply from the house consumer unit, sockets, lighting and a heating solution, tested and certified.
Can it have a bathroom?+
It can where drainage allows, either by gravity to the existing run or with a pumped solution. It changes the cost, so we settle it at quote stage.
How long does it take to build?+
Typically weeks rather than months, depending on size, base type and access. The programme comes with the quote.
How much of the garden will be disturbed?+
The base area plus a working margin and the route for materials. We make the ground good around the finished building.
How long will it last?+
It is a permanent building, not a shed: timber frame on an engineered base with a maintainable external finish. The completed work carries an insurance-backed guarantee.
Do you serve areas outside Farnborough?+
Yes, Camberley, Farnham, Guildford, Godalming, Crowthorne, Sandhurst, Aldershot, Fleet, Frimley, Bagshot and Yateley.

Services that pair with garden rooms

Garage Conversions
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
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
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.
