This superb quality summerhouse is approximately 13'1"x13'1" (4.0x4.0m). The walls are 45mm thick, which is almost four times thicker than the majority of summerhouses and is a specification usually found on log cabins. The floor and roof are substantial 19mm thick tongued and grooved boards. Other quality features include two sets of joinery double doors, a metal ridge cap and four double opening windows with leaded low level glazing. The doors and windows are doubled glazed and have an attractive curved top as standard. The eaves height is a generous 7'4". Insulation is available as an optional upgrade for the floor and roof. Further options include decorative felt roof tiles and a coloured paint treatment in a choice of colours. Fixings and instructions are supplied for self assembly.

QUALITY CONSTRUCTION: The specification of these summerhouses share many features in common with our log cabins but with the benefit of pre-fabricated panels to simplify the installation. The walls are 45mm thick (almost four times as thick as the vast majority of summerhouses), attached to substantial framing. Each board is double grooved for superior draughtproofing. Double glazed doors and windows are included as standard. Another quality feature is that the top boards in each wall are chamferred to better follow the lines of the roof. The pre-assembled floor and roof boards are each 19mm thick, which also compares favourably with many garden buildings.

NORDIC SPRUCE: This building is manufactured from 100% Nordic Spruce, the best quality timber used in log cabin construction. Nordic Spruce is grown primarily in the well managed forests of Scandinavia, Siberia and the coldest parts of Northern Europe. The cold climate ensures slow growth. The growth rings are much closer together than trees grown in warmer climates. As a result the timber is heavy and durable with a dense grain pattern. These forests are expertly managed on a sustainable basis so Nordic Spruce is an enviromentally friendly choice.

NATURAL WOOD: First, high grade timber is dried in kilns until it reaches the optimum moisture content, then it is planed smooth and machined into tongued and grooved logs and boards. Next the logs are precisely machined to ensure a precise fit when assembled. When you unwrap it the wood is untreated. We recommend treating it after the building has been successfully installed and ideally within a week or two to provide the best protection.

CHAMFERRED TOP WALL LOGS: This high specification building features a subtle quality feature. The top log in each side wall is chamferred to the same angle as the roof slope. This little detail provides much improved insulation and draughtproofing. It also provides a much neater internal appearance and the roof boards are easier to fix. This simple design feature eliminates an obvious cold spot. The benefits of this feature are magnified if roof insulation is specified.

OCTAGONAL BUILDING SIZES: For ease of reference these octagonal summerhouses are measured as a rectangle. The first dimension listed is the overall width from side to side and the second dimension is the depth from front to back. Sizes are sometimes rounded to the nearest nominal size for ease of reading but the correct external wall sizes are listed alongside the price. These sizes do not include the roof overhang. Many other suppliers quote the overall roof size which is much larger. All sizes are approximate.
