Year-Round Use

Every one of our garden room buildings is designed and built to be used all-year-round. Our insulated garden rooms control the outside elements and keep them at bay to create a space that is comfortable, healthy and dry. Premium grade insulation is used throughout our buildings, with a complex breathable membrane allowing a directional flow of air and moisture out of the building. We also use industry-leading double-glazing in our windows and doors.

What’s more, every building comes with a free-standing radiator included in the price.

Work/Life Balance

A garden room is the perfect blank canvas to use for any purpose you should need it for. Think outside the box and create your very own home gym, office, art studio, yoga room, garden bar, music studio, games room, man cave, reading room, beauty salon and much more!

Garden rooms are not bound by limitations that a room in your home may have. Being detached from the house you can complete control over the environment. Private, bright and unique.

What’s more, you can create a multi-purpose garden room using clever open-plan furnishing or our partition wall option.

Cost to Commute

A garden room office is one of the most popular uses of our buildings, and it makes sense why! These unique buildings are perfect for home offices. Being detached from the home gives space and privacy to focus on your work in a professional and controlled environment. Achieve a greater work-life balance by locking the door and walking away at the end of your workday, leaving the office behind you.

Save time and money from your commute to work by working from home in the comfort and privacy of your own garden room office. The environment will thank you for it too.
