All our builds come fully insulated and ready to use. Heating, electrics, foundations and finishing touches are all included in the price.
There’s no hidden extras, no unexpected costs. Just clear, honest pricing for a high-quality building that’s built to last.
A full self-contained home in the garden
Our Granny Annexes are perfect for multi-generational living. Every annexe includes kitchen and bathroom facilities, full plumbing, heating and electrics, and can be customised with one or two bedrooms.
These are real homes, built to the same standards as traditional housing but faster and more cost-effective. Whether it’s for elderly relatives, adult children or guests, this is a comfortable and private long-term solution.
Pre-designed layouts with flexible options
Garden Lodges are based on our most popular annexe layouts. They’re built in two sections, delivered to site and reassembled, which speeds up the whole process.
You can still choose your finishes and extras, and the end result is a warm, secure and fully connected home in your garden. All lodges comply with the Caravan Act and are approved for residential use.
Simple, cost-effective and ready to enjoy
Our Standard Garden Room is ideal if you just need extra indoor space that feels like part of the home. It’s warm, dry and finished to a high standard inside and out.
Whether it’s a snug, a hobby space, a reading room or just somewhere peaceful to retreat to, this model gives you a clean, flexible space that can be used however you like. You can also choose from a wide range of finishes to match your garden.
Designed for daily use and modern working
If you work from home or need a creative space that’s separate from the house, the Garden Office or Studio gives you a quiet, professional environment. It’s fully wired, heated and plastered inside just like any normal room. We can also build in custom storage, desks or even a toilet if required. You’ll have a comfortable space that works around your day and helps you stay productive.
All our garden buildings are fully fitted and ready to use, with no hidden extras. We include:
All our doors and windows come fitted with A-rated, energy-efficient double glazing to help keep your space warm in winter and cooler in summer. They’re secure, low maintenance and built to last.
A full-height glazed frontage brings in plenty of natural light and creates a bright, open feel. It includes a secure main entrance door that’s easy to access.
We use heavy-duty screw pile or concrete pad foundations for a stable, long-lasting base. These systems are approved by building control and suitable for most garden types.
Every interior is finished with plasterboard and a smooth skim coat. This gives a proper home-like finish, ready for you to decorate however you like.
Our buildings are constructed using SIPs panels throughout. This provides excellent insulation and creates a strong, warm, and quiet structure you can enjoy all year round.
The roof is covered with a single piece of Firestone EPDM rubber. It’s waterproof, long lasting and topped with decorative gravel to improve drainage and extend its life.
We include outside LED lighting as standard, plus a double outdoor socket. These are ideal for garden lighting, tools or charging appliances.
The price includes all cabling and connection back to your home’s power supply, up to 30 metres. No hidden costs or need to arrange your own electrician.
Each room comes with plenty of plug sockets, including USB charging points and modern dimmable LED downlights to suit how you use the space.
A slimline, wall-mounted electric radiator is included as standard. It comes with a 7-day timer and thermostat so you can set it to run just how you like.
We install rear guttering and a downpipe to keep water flowing away properly and protect your cladding and foundations.
Windows and doors are fitted with multi-point locking systems. Cladding options include long-lasting materials that don’t need painting or regular upkeep.
All electrical work is carried out by qualified installers and comes with Part P certification for complete peace of mind.
Every building comes with a full 10-year guarantee covering the structure, roof and major components, giving you long-term confidence in your investment.
