Deans Garden Bar And Pub At home
The Cartledge family live in a four-bedroom new-build house in Dorset. The family were looking to create extra space at home for a unique extra lounge space, where they could enjoy their favourite tv programmes (sports or shows) in peace without disrupting the other members of their household.
Dean says “I watch the football and rugby league in here with my son, Louis. He also hangs out in here with his friends as it’s much cheaper than them all going to the pub and they can watch whatever they want on the TV.”

Fantastic Room in a little London garden!
We now have an amazing room at the bottom of our garden that fits in beautifully and feels as though it has been there for ever. All the staff were incredibly helpful and friendly and the entire process was very straightforward.

Excellent choice of supplier for my Garden Studio! So pleased
Green Retreats deserve every single one of my star ratings! They have been very professional right from the start, from welcoming me to their warehouse to helping me make the right choice through to a fabulous installation. The finished studio is amazing, a top quality build and the installation teams were timely, polite and very hard-working.
Thanks to you all…what a fab company!!

Fantastic product and service to match
We had a 3.5m by 5m garden room installed last month and we are delighted with the result. We are using it as a home gym and love the extra space it has given us! The building also looks fantastic at the bottom of our garden. Green retreats have been an absolute pleasure to deal with. In summary I have been very impressed by both the product and the service provided by green retreats and highly recommend!
Man Caves FAQs
If you are interested in one of our garden room buildings, order a 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.
Planning permission is not normally required for garden rooms as thy 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.
Yes, we can install partition walls as an optional extra 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.
A garden building, including a dedicated man cave garden room will add value to your home! Leading property experts estimate quality garden buildings add 1.5 times their value to a home.
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 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 a wall-mounted radiator.
