Specifications of Garden Rooms

Here is an explanation of the methods and materials employed to construct our range of Garden office rooms and lodges

Floor and foundations

We use ground screw technology for our foundations and create the base just above ground level. The base is then constructed using 150mm x 50mm treated timber joists on top of the foundations.


The walls are built using structural grade 90mm x 38mm cls timber, then externally lined with 11mm osb sheets to add maximum strength and rigidity. The walls are then covered with breathable vapour barrier. Timber battens are then fit ready for the Thermowood cladding and trims to be fixed to.

Roof/roof covering

The roof is constructed using structural calculated wood joists and finished with 11mm osb sheets. The roof is then finished with market leading EMBD rubber roof covering and finished with black Fascia boars and breathable suffix


We use 90mm of PIR foil backed solid insulation panels in between the wall and floor joists and in between the studs of the walls.

Exterior finish

All of our garden room, lodge and garden office range is clad in heat treated thermowood. During the heat treatment of thermowood, chemical and structural changes occur which improves its basic characteristics. This vastly improves the timber for exterior use. All of our range comes with Black guttering and down pipe.


Each garden room is supplied and fitted with a comprehensive electrics package comprising: a consumer unit, 3 double sockets, 4 LED downlighters, 2kW convector heater and Ethernet Internet connection where feasible. All finished in white


We use high quality anthracite grey with white interior UPV-c french doors and windows, complete with toughened double glazed glass and high security 5 point locks. An Aluminium bi fold door and window upgrade is also available as well as an upgrade.

Interior finish

All of our range is complete with traditional plasterboard and plaster finish and decorated in white as standard. Premier laminate flooring is laid on top of an 18mm sub floor. White MDF pencil round skirting board is then fit to complete the room. We also offer internal walling as an optional extra
