JOINERY DOORS AND WINDOWS: A feature of these quality summerhouses is the joinery doors and windows with morticed and tenoned joints throughout. These intricate joints are harder to pull apart and therefore stronger. The ends of the timber are also better protected and therefore more durable.

PLANED SHIPLAP CLADDING: These summerhouses feature smooth planed fully interlocking tongued and grooved shiplap wall cladding. This design ensures that rainwater drains faster and the timber dries quicker, which ensures a longer life for your summerhouse. Our shiplap is fully tongued and grooved which is stronger than the half lap shiplap or rebated shiplap used by some others.

HEAVY DUTY FRAMING: These heavy duty summerhouses feature exceptionally strong framing, which ensures a more robust and durable building. Framing timber is normally supplied in standard timber sizes. The nominal size is the size before machining. The finished size after planing is normally around 5mm smaller. Framing of at least 50x25mm or 38x38mm nominal thickness is recommended for smaller summerhouses up to 6'x8'. Framing of at least 50x38m nominal thickness is recommended for larger summerhouses up to 8'x10'. Framing of 2"x2" or 50x50mm nominal thickness or larger is recommended for the largest summerhouses.

TOUGHENED SAFETY GLASS: Toughened safety glass is around 6 times stronger than normal glass so it is less likely to break. When it does break, toughened glass breaks into harmless small pieces. This makes toughened glass the best option for all the family including children, pets and the elderly.

SIZES - DEPTH AND WIDTH: Sizes are sometimes rounded to the nearest nominal size for ease of reading but the correct external wall sizes are listed alongside the price. The first dimension listed is the width and the second dimension is the depth. The width refers to the angled gable walls at the front and rear including the door wall. The depth refers to the side walls. The sizes listed are the external wall sizes. These sizes do not include the roof overhang. Many other suppliers quote the overall roof size which is much larger. All sizes are approximate.
