The premise with plinth foundations is that the plinths made up of base pads and a top pad which has adjustable fixings are spaced evenly under the garden room.
Plinth foundations can easily overcome problems with an uneven site by additional base pads to raise the foundation where the ground drops away.
Concrete Slab Foundations
(Reinforced insulated concrete floor slab)
With concrete slab foundations the vegetation is removed from the site and the ground excavated - the depth will be dictated by the site conditions and the size of the building. A layer of hardcore is laid and then compacted to create a solid level base on top of which a DPM is laid, then PIR isulation boards, before pouring a mesh reinforced concrete floor slab, 100mm thick.
The Walls, floor and roof are insulated using PIR rigid thermal insulation panels. Apart from being the most technically advanced insulation available, PIR rigid thermal insulation panels will not slip inside the cavities or suffer from attack by mould, fungi, mildew or vermin.
The Timber walls are wrapped in a waterproof breathable membrane. This breathing membrane acts like a one way valve and allows natural moisture to escape out of the building.
Treated C16 flooring joists framework, PIR rigid thermal insulation, 22mm moisture resistant T&G flooring boards, foam underlay, quality laminate flooring with matching skirting boards.
Exterior timber cladding hand fixed, treated 50 x 25mm batten, breather membrane. 100 x 50mm treated C16 graded structural timber containing PIR rigid thermal insulation boards taped and sealed, vapour barrier, 12.5mm plasterboard and plaster skim.
Inside our garden buildings you will find traditional plaster boarded and skimmed walls and ceiling (no vinyl or plastic wall boards!!). A professional plastered interior gives a warm, elegant surface finish and will help with sound insulation and improved energy efficiency.
Western Red Cedar (alternatives are available)
Olive Garden buildings include high quality Western Red Cedar tongue and groove external cladding as standard. Western Red Cedar is the most desired external timber cladding due to its rich and variable colours, high resistance to decay, durability and natural preservatives. The exterior Western Red Cedar timer cladding compliments all environments, is 100% maintenance free and has a typical life span of 40 to 50 years.
EPDM roofing membrane and trims, on OSB/ply, decking on PIR rigid thermal insulation boards laid over breathable waterproof membrane/vapour check. Structural OSB or plywood deck, laid on C16 graded structural timber roof joists, finished to underside with 12.5mm plasterboard and plaster skim. The roof perimeters are finished with black ash PVCu facias & soffits. Black half round guttering and a down pipe to ground level is fitted to the rear of the structure.
External Doors and Windows
Supplied double glazed with dark grey PVCu or aluminium profiles on the outside and white on the inside. Each door and window section is supplied with heat saving argon gas filled double glazed units and warm edge super spacer bars as standard.
Each building is fitted with a comprehensive system comprising: Mains consumer unit, double sockets, adjustable spotlight lighting and light switch & efficient electrical radiators, all supplied in a brushed stainless steel finish. All wiring is fully concealed within the timber framework.
Walls constructed from treated s.w. studs, finished externally with OSB, and studs filled with high performance insulation boards. Studs finished internally with plasterboard on vapour barrier. Walls finished externally with treated s.w. battens on breathable membrane, and finished with decorative timber boarding (type and style to client's choice)

Floor deck constructed from treated s.w. joists sat on proprietary foundation pad system, with high performance insulation and vapour barrier below floor decking of moisture resistant floorboards, to receive final internal finishes to client's choice.
Optional external decking areas to have high quality hardwood decking boards for a long lasting durable finish
