We’re not like all those other garden annexes.

Not at all.

What’s different about us? The materials and construction method we use. Traditional annexes use timber. Our luxury annexes are made using modern methods of construction using a sturdy steel frame and non-combustible aluminium cladding - so it’s built to last. They’re also well insulated so they can be enjoyed all year round.

Our new Brighton showroom opens in April 2021. Join our waitlist to get up to £5,000 off, and we’ll let you know when we open.
