Forest Garden's Mendip Log Cabin is a mid sized garden building with a footprint 5m wide x 4m deep. It's simple, modern pent roof design is complemented by a high specification which includes 45mm thick interlocking log walls, 19mm tongue and groove floor and roof, double glazed double doors, two tilt and turn double glazed windows to the front and a 3/4 length double glazed tilt and turn side window that can be positioned in the left or right wall. All windows are double glazed with toughened glass.

The Mendip's overall dimensions are 5.24 metres wide x 4.66 metres deep (17 x 15 feet) and the front of the roof features a useful 60cm overhang for weather protection. The internal floor dimensions of 4.7m x 3.7m give a total floor area of 17.5 m? (188 square feet) which is big enough to have a generous home office and lounge or lounge and dining area or a great leisure room for gaming, TV and hobbies.

With plenty of windows to allow natural light in this makes the Mendip log cabin a very usable and versatile extension to your living space. The internal depth of 3.7m and width of 4.7m give lots of wall space for shelving, cupboards or other furniture.

Different roof felt options are available with this option being supplied with 24kg weight Polyester felt (without underlay). The felt has a polyester fibre base layer that makes it much stronger and more tear resistant than non-polyester grades. With more than twice the tear resistance of conventional mineral felt it has a life expectancy of up to 15 years when fitted correctly.

We recommend the small upgrade to Polyester felt with additional black sand felt underlay.

All deliveries are made by vehicles with a crane off-load facility and with an optional professional assembly service. The log cabin must be built upon a solid and level surface such as a poured concrete base.
