TGO Range

TGO stands for The Garden Office, a brand released by Green Retreats in 2006 to attract the growing ‘work from home’ movement. However, these buildings can be used for much more than the name suggests, just like any of our building ranges.

The unique styling identity of the TGO range is the highlights of graphite or black in its exterior styling, creating an elegantly striking feature in the garden. The TGO Range can also accommodate a wrap-around effect corner window.

The Garden Studio range was launched by Green Retreats in 2016 to offer a scaled-back version of our popular luxury garden room buildings from our other ranges, Green Retreats and TGO.

The GS Range of buildings is available at a lower price point due to its simplified exterior design and fewer optional upgrades. What these designs lack in customisation they make up for with the same excellent quality of build using the same high quality materials and craftsmanship you’d expect for the core Green Retreats designs.

Benefits of a Garden Room

There’s so many reasons to choose a garden room to create extra space. We’ve put together just a few of them for you…

Cost Comparison

Garden rooms make for a cost-effective alternative to traditional home extensions, being cheaper per square metre and having no hidden costs involved.

When compared to the conventional single story extension, conservatory or loft conversion, a garden room is a unique and exciting alternative that is open to a wider possibility of uses than their alternatives.

What’s more, garden rooms rarely require planning permission and they are installed on-site by us in just 2-5 days – making them a convenient and hassle-free addition to your home.

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.
