Garden rooms, home offices and annexes, delivered complete across the UK
Bespoke garden rooms, offices and annexes, precision-built off site and delivered ready to use. A fixed price agreed before we start, no builders in your garden, and often no planning permission needed. Tell us what you need the space to do, and we'll design it, price it and deliver it.
We don't sell buildings off a shelf. Every Bastion Homes space is designed around you: your plot, your layout, your finish. Whether it's a garden office, a home gym, a studio or an annexe for family, we build to your brief so the space works exactly the way you need it to.
That means no compromises and no wasted space. From the first conversation, we design around your home, your garden, your budget and how you'll actually use the room, then finish it to a high standard inside and out, so it feels like a natural, considered part of your property.


An office to escape the kitchen table. A gym steps from the back door. A studio, a snug, or a private annexe for family. A Bastion Homes space gives you room to live, work and relax, without the cost and upheaval of moving house.
Every build is fully insulated and properly finished, with lighting, power and heating built in, so it's just as comfortable in January as it is in July. And in most cases there's no planning permission to worry about, as many fall under permitted development. We'll advise you honestly from the outset on exactly where you stand.
Your quote is your price. We agree a transparent, fixed-price cost before any work begins, so there are no variations, no creeping costs and no surprises. You know exactly what you're paying from the very start.
Because your space is built off site and delivered complete, there's no building site in your garden and no trades coming and going for months on end. It arrives fully fitted and finished, ready to use from day one, with none of the mess or disruption of a traditional extension.


A Bastion Homes building isn't just extra space, it's an asset. Because it's modular, you can adapt, relocate or repurpose it as your needs change, so it holds its value in a way a traditional extension simply can't.
We're a veteran-owned business, proudly represented by brand ambassador Gregg Stevenson MBE, Paralympic gold medallist. Doing things properly and standing by our word is the whole point of how we work. That's certainty, built in.
