Base Preparation & Delivery Information

Assembly & Aftercare Guide

Achieve your work/life balance with the Xtend range of garden buildings from Forest Garden. They have everything you could wish for in a home ofﬁce - contemporary looks, real energy efﬁciency and ease of construction.

Space is at a premium in most homes and extensions are costly. An Xtend garden building is constructed from high quality, energy efﬁcient materials and is underwritten with a 15 year structural guarantee

Xtend is a clever choice for your garden building as it comes delivered in pre-cut modular structural insulated panels (SIPs) ready for assembly. Some of the best designed new homes are now made this way, so why not your new garden building? A step-by-step guide means the build is incredibly straightforward.

Keeping you warm in winter and cool in summer, Xtend delivers real energy efﬁciency. Double glazed windows, highly efﬁcient insulated walls, roof and ﬂoor combine to drive down energy costs. It’s a fact that Xtend garden buildings can be as energy efﬁcient as a new-build home – with an EPC energy rating of C (with the potential to improve this to category B with the addition of a photovoltaic solar panel).
