Diederick Modern Summer House 6.25 x 3.75m
Transform your garden with a summer house
Manufactured with 28mm interlocking Spruce logs, our Diederick summer house offers durability and comfort. This summer house features an indoor space (2.49 x 3.49m) that you can use as storage, a garden lounge or even a home office, accompanied by a 3.5m canopy which provides the perfect place to relax, dine or entertain in the warmer months while staying sheltered from the elements. The canopy can be positioned either side of the summer house so the building can be customised to meet your needs.
This model will allow you to add a stylish, self-contained space in your garden that can be used as additional living space in the warmer months. For a summer house that can be used year-round, we recommend adding insulation during installation.
Pent Roofing Options:
We offer three different types of roofing for the pent log cabins.
Felt Roofing Kit: Standard rolls of roofing felt. Supplied with clout nails and felt glue. This option has the shortest lifespan of 2-3 years and will need replacing over time.
Easy Roofing (High Performance Polyester Base): The second best option. Arrives in 5x1m rolls with a self-adhesive backing. Can be finished with metal or timber roofing trims. Lifespan of 15+ years.
EPDM (Ethylene Propylene Diene Terpolymer) Rubber roofing: The best option. Supplied in a single sheet with no natural overlaps. We supply two types of adhesive: a spray glue for the majority of the surface area and a tube for a fill gun for the edges. Metal modern roofing trims are a good extra to consider. Lifespan of 20+ years.
Alternatively, if you prefer to use your own roofing material, you can purchase this model with no roofing option.
