The Mendip 5m x 4m Double Glazed Log Cabin from Forest is a modern looking garden building with a pent roof, double glazed double doors with two front tilt & turn double glazed windows, plus one tilt & turn side window (that can be positioned on either side of the building), the interior is filled with natural light. With 17.4 square metres (188 sqft) internal floorspace, this is a great size building if you wanted to use it as a large home office, gym, hobby room or teenagers den. The timber used to construct the log cabin is made from slow grown FSC Nordic Spruce, kiln dried and left untreated for you to paint or stain in a colour of your choice. The 45mm thick walls, 19mm tongue and groove floor and roof, roofing felt with a polyester fibre base layer and toughened double glazing combine to create a strong building designed to withstand all seasons of the British weather.

The cabin is supplied as a self assembly kit, with instructions and fittings. The log cabin is supplied with individual interlocking logs that slot together for straightforward assembly. If you would prefer to leave all the hard work to the experts at Forest, then opt for the home delivery and construction package. The cabin must be built on a solid level base, such as concrete or tarmac.
