Why a Garden Annexe Makes More Sense Than a Home Extension in 2025
Increase your space
When space runs out inside the home, most people assume the next logical step is an extension. But in 2025, more and more homeowners are rethinking that approach and turning to garden annexes instead.
Whether you’re trying to create space for an elderly parent, give your adult children some independence, or simply need a self-contained living solution, a garden annexe offers everything an extension does, with none of the headache.
Less Disruption, More Results
A home extension means months of dust, noise and builders walking through your house daily. With a garden annexe, everything happens outside with minimal mess, no disruption to your everyday routine. Our steel frame annexes are installed with absolute precision and minimal impact on your home life.
Designed for Living
Don’t think sheds. An annexe is fully insulated, built to modern housing standards and finished with high-end materials throughout. Smart hearing, fully fitted kitchens, bathrooms, storage, bespoke joinery, every part is tailored to individual needs. These are genuine spaces, just outside the main house.

- Shower Rooms
- Bedrooms
- Smart Heating
- Accessable Entrances
A Faster Route to Space
On average, an extension takes 6 to 12 months to complete (longer if you hit planning delays or budget overruns). A Garden annexe are typically designed, manufactured and installed in a fraction of that time. Once foundations are in, our steel builds go up fast and because it’s all handled in-house, there’s no chasing trades.
Fixed Costs, No Spiralling Budget
Extensions are notorious for creeping costs. Once you open up a wall, you often uncover new problems that weren’t budgeted for. A garden annexe is a controlled build: designed off-site, constructed with accuracy, and delivered exactly as quoted.
Built for Accessibility
If the annexe is being used for an elderly relative or someone with mobility needs, accessibility isn’t just a nice-to-have but an essential. We design with that in mind. That means flush thresholds for easy access, wider doorways, level flooring throughout, and the option for ramped entrances if needed. Everything is thought through from the start, so there’s no need for retrofitting later. It’s a smarter way to future-proof the space and make sure it’s comfortable and safe for whoever’s living there.
