The size and specification of this log cabin make this mid-large size model perfect for a wide range. The traditional reverse apex roof design offers a little more headroom in the centre of the cabin where the apex height is 2.47 metres. This substantial log cabin has a footprint 5m wide x 4m deep and uses 45mm thick interlocking logs for the walls and 19mm tongue and groove boards for the floor and roof. Double glazed double doors at the front have a tilt and turn double glazed window on either side with two more 3/4 length double glazed tilt and turn side windows (one either side) so plenty of natural light can get in. All windows are double glazed with toughened glass. This is big enough to be a generous home office and lounge or lounge and dining area or a great leisure room for gaming, TV and hobbies. This impressive size and specification make this garden building a very usable and versatile extension to your living space. Different roof options are available: polyester felt with or without underlay, a higher grade/weight (34kg per 10m) polyester felt with underlay or felt shingles with 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. 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.
