WALLS
A sturdy joinery-grade framework with a total finished dimension of 85mm x 34mm provides the strong skeletal structure at the heart of the wall structure. This is screwed together and the exterior protected against the elements by way of a VPL vapour barrier and an external cladding of your choice:
• LP Strongcore resin and engineered wood composite cladding (painted externally in a colour from the Tikkurila Opaque paint system range)
• 19mm (15mm finished) Pressure treated T&G Shiplap
• 22mm (20mm finished) Pressure treated T&G Loglap
We sandwich the revolutionary Superquilt multifoil insulation between the wall framing to create an insulation barrier with superior performance before cladding the interior with 16mm (12mm finished) thick horizontal T&G pine matchboarding for a warm soft appearance. We can clad vertically upon request for a small additional sum.
FLOOR
19mm (15mm finished) pressure treated T&G floor boards set on a 70mm x 34mm enclosed floor frame and joists. For insulation purposes we insulate between the floor joists with Celotex/Kingpan foil-backed PIR insulation. There is an option to specify 22mm (20mm finished) T&G floor boards in lieu and you can even specify laminate flooring in a selection of colours from the Howdens Professional V Groove range if desired (see colour options below).
ROOF
All roofs are constructed using the principles of a ‘warm deck’ roof system to maximise space within the building using Celotex/Kingspan foil-backed PIR insulation laid atop the roof deck. Pent roof buildings benefit from being covered with the market leading Firestone RubberCover EPDM rubber roof membrane which is glued to the roof deck with a special adhesive. The roof covering is designed to last the entire lifespan of the building. Apex roof buildings come with long-lasting decorative felt tiles (in a choice of green, red or black) specified as standard with an option for Onduvilla (a traditional clay-tile effect), Tapco (a classic slate effect roof tile) or a warm natural cedar shingle roof
GUTTERING
Black PVC gutters and downpipes are fitted as standard in order to harvest the #rainwater run-off whilst protecting the building.
HEIGHTS
Our standard design would see a very generous clear internal height. Please note that all dimensions quoted are indicative/nominal and that these may vary depending upon building design and roof covering:
Pent models:
Low wall height: Internally 2.12m (7’) Externally 2.21m (7’ 3”)
High wall height: Internally 2.25m (7’ 5”) Externally (to top of roof canopy) 2.49m (8’ 2”).
Apex models:
These buildings are made to order but a typical configuration might see the following dimensions used:
Low wall height: Internally 2.12m (7’) Externally 2.21m (7’ 3”)
Ridge height: Internally 2.25m (7’ 5”) Externally 2.80m (9’ 2”)
DOORS & WINDOWS
We fit all buildings with high specification PVCu doors and windows as standard. These are similar to those fitted in modern residential properties and features include multi chamber frame profiles, draught excluders and a high standard of ironmongery. All glass within the doors and windows are 28mm sealed units and there is a wide range of colours available (see below) at no extra cost.
ALL YEAR ROUND USE
With the highest specification throughout this is truly a year-round building which will be every bit as comfortable as your home itself. The double glazed windows and the high grade insulation throughout the building ensure that your investment is warm in winter and cool in the summer.

Usually, garden rooms don't require planning permission as long as they meet specific criteria. This includes being a single story with a maximum height of 2.5 metres and must be located within two metres of a boundary.
However, different restrictions and permissions may be required if your garden room is larger, situated in a protected area or intended for business use.
Essentially, different areas have different requirements in terms of planning permissions, so we recommend checking with your local planning authority or consulting with our experts to ensure that your garden room is in compliance with all regulations.
Insulating a garden room will make it useful all year round and comfortable.
1st Choice Leisure Buildings provides many garden room options that have insulation already included, but if you're looking to enhance or add insulation to a garden room that's already built, here's how to do it:
