The key benefit of the Xtend buildings lies exactly in their name: they are designed as extensions of your living space. Working from home has never felt more natural thanks to the quality and comfort provided by the Xtend line, and having a separate working space of such high specification will add to your motivation and freedom. If you decide to use your Xtend building for leisure, you won’t be disappointed either. Anything, from an atelier to a luxuriant guesthouse to a garden library will not only look great, but also feel right. The Forest Xtend 3.0m Installed will enrich your lifestyle and promote your well-being. The first thing you’ll notice in your Xtend is the visual impact of its modern architecture, which translates into straight lines, a sleek pent roof with overhang, anthracite grey frames and fascia, and vertical elements such as floor-to-ceiling windows and vertical cladding. The building features walls at an impressive 97mm thickness. This is due to the 75mm polystyrene insulation sandwiched by two sheets of OSB. Add to this the Structural Insulated Panels, the internal and external cladding and cavities and you have a whopping 177mm total wall thickness! Similarly, the insulated roof is 122mm thick, and further adding to the energy efficient elements, the building features 28mm double glazing. Keeping you cool in summer and warm in winter, the Xtend is a dream garden building made for actual all-year-round use, and a proper extension of your living square footage at an affordable price. The ridge height, thoughtfully designed at 2.5m, means that you won’t be needing a special planning permission to build your Xtend. For your peace of mind, the building comes with a fifteen year structural guarantee. The installation fee is included in the price.
