Benefits of a Man Cave


A dedicated space to unwind and retreat for a stress-free escape from everyday life. Do as you please in your man cave.


A space away from the home to host your parties or sports fixtures. Everyone will be fighting to be invited to yours.


You’ll have a dedicated space away from your home to spread out and enjoy your hobbies, no matter what they may be.


Our buildings are designed for year-round use meaning that no matter the weather, you’ll be able to enjoy your man cave.

An Outdoor Man Cave creates space, rather than taking it away.

Our garden buildings are stand-alone structures, completely separate from your home. Being detached from the home offers freedom and privacy that you – and the other members of your household – will appreciate! Crank up the volume on your own or with friends without disrupting the harmony at home.

Garden buildings are a cost-effective alternative to a traditional home extension that can add value to your home. What’s more, the extra space you are adding is easily transformed to suit any purpose!
Think of it as your blank canvas. Got guests coming? Covert your Man Cave into a spare room at the drop of a hat!

Our garden buildings are a long way from a rickety and damp ‘converted shed’ – more than a ‘posh shed’ for that matter! Designed for absolute quality and comfort, our buildings are as warm and secure as a room in your home would be!

Our Transparent Pricing

We include everything needed to get your building up and running within your quoted price – including base installation and VAT. As well as this you will receive a french sliding door set, flooring, plug sockets and much more to get you started as soon as construction finished.

Built to last, our buildings are suited for all year round. Meaning you can exercise at the comfort of your home whether it be rain or shine – no need for trips to the gym in the rain! Completely sealed and insulated just like a room in your home, our products can be used during the freezing winter months, and during the pouring rain.


Close the door behind you and step into a space that is all your own. Your Man Cave is a sanctuary where you can be you, without judgement.
Fill it with what makes you happy, relaxed or what excites you. Create the space you have dreamed of since you purchased your first home. Create a home cinema room, games room, garden bar, sports centre, a shrine to your favourite football team, guitar studio, pool table room – or all of the above!


If you are interested in one of our garden room buildings, contact us for a comprehensive brochure & price list, along with any additional queries you may have.
A visit to one of our showrooms gives you a real feel of the quality we offer and is a great way to start your project. We provide a free on-site or virtual design consultation service, allowing us to have a comprehensive look at your location, land and access. During this meeting, you are provided with samples of the building, and together we can design the perfect garden room to suit your requirements.

Planning permission is not normally required as our buildings fall under permitted development (built under 2.5m high externally). Most houses, even in conservation areas and areas of outstanding natural beauty (AONB), have permitted development rights.
Flats and listed buildings have no permitted development rights, so will always need planning permission. Don’t worry though, as planning is a relatively simple process for our garden rooms and we are on-hand to help with this process.

Yes, we can install partition walls in any of our larger sized garden rooms. Please enquire for more details.

Our garden room structures will need to remain free-standing due to the nature of their construction. However, we can build as close as 400mm to any solid obstacle, such as your house.

We do not offer bespoke building options. However, we do offer many different sizes and styles to suit your tastes and budget. You can start to design your building using our visualiser.

We don’t offer a completely sound proof solution for your garden room. We do, however, offer an acoustic pack which reduces the transfer of sound to approximately -45db – however this is not ‘sound proof’. Although we use industry-leading acoustically laminated glass, this is the least effective component of our acoustic pack. Please bear in mind that the more glass you opt for on your garden room, the lesser the effect the acoustic pack will have.

We offer a complete electrical connection from your house to the garden room at an additional cost, which will be confirmed at your design consultation. However, you are more than welcome to use your own preferred electrician for this.

If you are looking to install a bathroom or other facility that would require water to your building, we would be happy to liaise with your plumber of choice to ensure they are comfortable carrying out all plumbing work required to and from the building.

No, our design consultants can work around any sheds, decking, garages etc that may be in the way of where your building will go. We will just ask that you send a photo of the ground under the obstacle once you’ve moved it before your base is installed.

As standard, all of our buildings are clad in maintenance-free Scandinavian Redwood. Also included is a 2.3m French or sliding door set and an opening lozenge window. We also include a choice of four flooring options, three double plug sockets, a choice of internal lighting, an external light, a 2-way consumer unit (fuse box) and oil-filled radiator.
