Outdoor Man Caves

Need space to unwind? At Green Retreats we think outside the box. Detached from the home, our stand-alone luxury garden buildings make for the perfect Man Cave as your retreat from the normal stresses of life.

A Man Cave by Green Retreats is a cost-effective solution for adding more space to your home, not taking one away by using up a spare room or an underused corner. Our buildings are a complete product, with everything you need included in the price – just add furniture!

Garden Bar and Games Room
Quite a bit more than just a ‘posh shed’.

Designed and made in the UK, our garden rooms use only the finest materials and quality craftsmanship for an architecturally stunning addition to your home and garden. Designed for use all-year-round, our garden buildings make for the ultimate man cave in the coldest winter months right through into the hot summers (what few of them we have!).

Why Choose an Outdoor Room?

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’ – and 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!

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.

How we design and manufacture our buildings means they are perfectly suited for use all-year-round. The walls, floor and roof are crafted using premium grade insulation for superior thermal qualities – keeping the outside elements at bay! What’s more, we use industry leading Pilkington K Optiwhite double glazing in our doors and windows.

Your garden building will feel as comfortable as a room in your home, with no damp and dreary feeling of a traditional outbuilding.

Our Manufacturing Process

Do I need planning permission?

Generally not! The design and construction of our garden buildings mean that they fall within permitted development rights – making the addition of one fairly straightforward for most customers!

There can sometimes be limitations based on where you live or the placement of your garden building on your land that could mean you will require planning permission. We can discuss all of this with you during your free design consultation.

If you do require planning permission, we have a team that will take care of the application process for you!

You can find out more about your permitted development rights on the Planning Portal website.
