Insulated, fully finished garden rooms designed and built across Gloucestershire

Garden Rooms in Gloucester
A garden room is the simplest way to add a room to a Gloucestershire home without touching the house. Instead of extending, moving or giving up a bedroom, we build a fully insulated timber room at the end of the garden and finish it inside and out, wired, heated and ready to use. LN Carpentry LTD designs and builds bespoke garden rooms across Gloucester and Gloucestershire, from garden offices and studios to gyms, garden bars and summer houses. Every room is built by our own team of five craftsmen, never subcontracted, and every one is made to suit the garden it sits in.
Most garden rooms begin with a conversation about how the room will be used. A garden office needs daylight, quiet and enough sockets for two screens and a printer. A home gym needs head room for a bike or a rowing machine, a resilient floor and proper ventilation. An art or music studio needs stable light and space to leave work out between sessions. A garden bar needs a wide opening, somewhere to sit and a run for a fridge. A summer house needs glazing that opens to the garden. We take those requirements, measure the space and design a room around them, then agree the size, the cladding and the finish before a single sheet of timber is ordered.
The structure itself is carpentry in its purest form. We prepare the base, cut and frame the walls in treated timber, insulate the floor, walls and roof, then clad the outside in the material you choose. Western red cedar weathers to a soft silver grey, thermowood keeps a warm brown tone, and composite cladding holds its colour with almost no maintenance. Roofs are finished in EPDM rubber or GRP fibreglass, both seamless and guaranteed watertight, with a slight fall away from the house. Inside, the room is lined, skimmed or clad in timber, then painted or oiled, with sockets, lighting and heating fitted as part of the job rather than left to another trade.
Everything we build has to work in the Gloucestershire climate, and that shapes the details. Gardens in Gloucester, Quedgeley and Longlevens often sit low and hold water, so we raise the base and plan drainage before the frame goes up. Properties on the exposed ground around Painswick, Bishops Cleeve and Churchdown need heavier fixings, deeper roof overhangs and doors that seal hard against driving rain. Rural plots around Newent, the Forest of Dean and the villages along the Severn need thought about mature trees, leaf fall and access for materials. We plan all of it at survey stage, not on the day.
Bases and groundwork are where most garden rooms go wrong, so we take them seriously. Where a sound concrete slab or paved area already exists we build directly onto it, checking it for level and structure first. Where there is nothing, we lay a new reinforced slab, or use ground screws and screw piles where access is tight, the ground falls away or tree roots are close to the surface. Decking, steps and ramps are fitted after the room is up, so the doorway always meets the ground at the right height. If your garden slopes, we handle the levels properly rather than hiding them behind a step.
Insulation is what makes a garden room usable all year. We insulate the floor, walls and roof to a standard you would expect in a house, fit double or triple glazed aluminium or timber doors and windows, and seal every junction so draughts have nowhere to go. Electrics, heating and lighting are installed as part of the build: sockets where you need them, LED downlights or pendants, an armoured supply from the house, and a panel heater, underfloor mat or air conditioning unit for the seasons. We can also run a data cable to the room so a garden office connects as reliably as a desk indoors.
Planning permission is rarely a problem. A single storey garden room under four metres tall, with a pitched roof and no more than half the garden covered by buildings, usually falls within permitted development. There are exceptions: conservation areas, listed buildings, homes with an Article 4 direction, and any room within two metres of a boundary that stands more than 2.5 metres high. We check the size, position and use of every room we quote and tell you honestly whether a lawful development certificate or a planning application is the safer route. A room used for sleeping must meet building regulations, and we build to that standard when asked.
Cost and programme are agreed up front. We price the base, frame, insulation, cladding, roof, doors, internal finish and electrics separately, so you can see exactly what each choice adds, and we give you a clear start date and a programme that usually runs three to five weeks on site once the base is ready. Decking, canopies, a toilet or shower room and air conditioning are priced as options. Because we are a carpentry and joinery company rather than a reseller, we build the room with our own hands and stand behind it.
LN Carpentry LTD is based in Gloucester and has traded for fourteen years, with Constructionline Gold accreditation and full insurance. That matters more on garden rooms than on most jobs, because the room has to perform every day of the year, not just look good on handover. Neil or Liam will visit your garden, look at the access and levels, talk through what you want the room to do, and give you a free, itemised quote with the options priced separately.
