Bespoke Garden Rooms for all Outdoor Spaces
All builds include electrics, heating, foundations and a full finish as standard. We make it easy from the very start.
Granny Annexes 
Garden Lodges 
Garden Rooms 
Offices & Garden Studios 
All our garden annexes, rooms and lodges come fully insulated and ready to use. What’s more, the price includes foundations, heating, electrics and all the finishing touches, so there’s nothing essential to add later.
Unlike some companies, we don’t advertise a low starting price and then add extra charges for groundworks, delivery and other essential items. Instead, we provide a transparent, fixed-price quotation tailored to your project and honour it.
As a result, you can budget with confidence, knowing exactly what’s included from the outset. There are no hidden extras or unexpected costs—just honest pricing for a high-quality annexe that’s built to last.
Our bespoke 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, two or three bedrooms.
These are real homes that meet the same standards as traditional housing, while offering a faster and more cost-effective build. Whether they’re for elderly relatives, adult children, or guests, they provide a comfortable, private, long-term living solution. Some of our garden annexes also comply with the Caravan Act.

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.

Our Standard Garden Room is ideal if you simply need extra living space that feels like part of your home. Better still, it’s warm, dry and finished to a high standard inside and out.
Whether you need a snug, hobby room, reading room or simply a peaceful place to relax, this versatile garden room adapts to your lifestyle. In addition, you can choose from a wide range of exterior finishes to complement both your home and garden.
See the table below for our standard garden room sizes and prices.
If you work from home or need a dedicated creative space, our Garden Office or Studio provides a quiet, comfortable environment away from the main house. Better still, it’s fully insulated, wired, heated and plastered throughout, so it feels just like any other room in your home.
We can also include bespoke storage, fitted desks or even a toilet to suit your requirements. As a result, you’ll have a practical, comfortable workspace designed to help you stay productive every day.

All our garden buildings are fully fitted and ready to use, with no hidden extras. We include:
The 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.
We construct all of our buildings using SIPs panels throughout. As a result, they offer excellent insulation and create strong, warm, and quiet spaces that 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, along with a double outdoor socket. As a result, you’ll have convenient access to power for garden lighting, tools, and 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 direct rainwater away efficiently. As a result, this helps protect your cladding and foundations for years to come.
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.
All prices below are fully installed and inclusive of the features listed above.
