We’ve not got the easiest flat to access and have had quite a few different trades guys here since we first moved in. None of them compare to Tony, Mark and Jason. They were really great, taking obvious pride in what they do and we’re really impressed with our office. They ended up staying until much later than we’d expected on the last day to ensure that everything was just right, despite knowing it would be a long journey home.
Ms S – March 2021

The Belle provides the perfect fusion of elegance and intelligent design, creating an ultra-chic garden office studio with redefined style, charm and hidden strength.

Garden Office Studio

The Belle range was created to offer more personalisation and styling choices and position itself as the ultimate rival to the man cave; intelligent, strong and with a charm of its own. Contemporary combined with simple, classic lines provide a serene and inviting space, this studio is irresistible and can provide a cosy retreat, a stunning garden office studio or a creative craft room. You can personalise the Belle further with a range of stylish, chalky colours and the optional New England panelled interior to create your own look.

Effortlessly Chic

The Belle’s effortlessly chic appearance from the outside is supported by a strong and rigid 100mm pressure-treated timber chassis, engineered and built by our proprietary TuSC®  construction. Each of our beautiful garden rooms are provided with lighting and socket options and finished with hand-painted exterior walls in your choice of long-lasting Owatrol coating, requiring minimal maintenance.

Create Your Own Space

Our range of gorgeous, chalky colours enables you to truly create your dreamy chic space, along with the freedom to configure the windows and doors however you wish, enabling you to create a calm and peaceful garden office studio. A contemporary external light can also add to the ambience of the building, making it an inviting space at night as well as the day.
