2: Annexe Accessibility Guides
Our articles and guides on the most appropriate ways to accommodate accessibility needs within an annexe.
Annexe construction is normally completed by way of A) Brick and block - costly, lengthy and problematic for planning permission. B) SIPS - a quick and cheap method of annexe assembly but without much strength. C) Hybrid modular - a super strong method of classic timber frame construction but with factory-built quality and on-site assembly and with moveability and heft.
3: How to Choose the best Annexe
Our articles and guides to help you choose the very best annexe for your requirements and to highlight some avoidable pitfalls. A Garden Annexe is constructed from a precision cut chunky timber frame from 300mm x 45mm Baltic Spruce glulam. To create a hefty 222mm thick wall, this is combined with a durable MTX cladding for an enduring end product with great structural strength, longevity and rigidity.

4: Annexe Technical Insights
These articles and guides answer any technical questions about a wide range of annexe specifications available in the market.
Garden Annexes are insulated with 100mm insulation in all walls, floors and ceiling to create a robust “insulated box”, to minimise the vagaries of the British weather.
Importantly, every panel of insulation is machine cut to maintain thermal integrity.
