Benefits of a Posh Shed


Taking the term shed and turning it on its head, a posh shed does more than it says on the tin and creates a living space away from the home to enjoy.


Every posh shed comes as standard with the essentials you need to feel comfortable in your room. This includes insulation, 2.3m french or sliding door and more.

Flexible Adaptable Space

Being detached means that you can get creative with your new space. Our luxury sheds made for the perfect garden office, art studios and much more.


Using industry-leading insulation systems ensures your building is comfortable all year round. Keeping the heat out during the summer the warmth in during the winter.

Real Case Studies

Take a look at some of our real customer case studies:


Unlike a traditional garden shed, our Posh Sheds have been designed to use all-year-round. At Green Retreats we craft each of our buildings with complex and breathable insulation layers in the walls, roof and floor. Our buildings will not feel damp or drafty, being completely watertight and breathable. What’s more, every building is fitted with premium Pilkington K double glazing and comes with radiator heating as standard.

Shed + Office = ‘Shoffice’

This is a term that gets bounced around quite a lot, and it absolutely hits the nail on the head. You need somewhere to work, you choose the garden, you think “shed!”, you think “office!” You’ve got a ‘shoffice’.

Our garden ‘shoffices’ are the ultimate posh shed solution for you to do just about anything in. Whether you are creating a ‘shoffice’ to work in or relax in, our posh sheds offer you everything you need, a space for year-round use that’s more cost-effective than an extension, which is generally built without planning permission.

All ‘shoffices’ are built using tried and tested construction techniques at our state-of-the-art manufacturing facility in Buckinghamshire. We use a mixture of traditional materials and modern composites, to create a posh shed with a lifetime of well over 30 years.

‘Shoffices’ from Green Retreats are the cost-effective, modern and stylish alternative to an extension, conservatory, loft-conversion or office rental solution.


There are 4 designs to choose from in over 70 different size configurations. We offer a range of personalisation options in the price, as well as optional upgrades at an extra cost such as bi-fold doors, cedar cladding and air-conditioning for that extra touch of luxury.


Our customers love us! We are proud that our customers have rated us 5 stars on the independent review site Trustpilot.

Not only are our buildings of the finest quality, but our service is too. This is one of the many reasons why architecture guru Kevin McCloud has given Green Retreats his seal of approval by becoming our brand ambassador!

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 is 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.

Yes, they are warm enough to use throughout the year as they are all well insulated and come with a wall-mounted radiator as standard.

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

Our garden rooms are not designed to be lived in as they do not comply with building regulations. If you would like to live in a garden room, The Annex is part of The Green Retreats Group and offers garden annexes with full planning permission, which comply with building regulations.

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.

Whilst our garden rooms are temporary structures and are moveable. It is worth considering that the costs to move a building is chargeable to you and can equate to an amount that does not make moving the building viable.

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 soundproof 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 ‘soundproof’. 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 in your garden room, the lesser the effect the acoustic pack will have.

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.

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.

Yes, all of our buildings come as standard with a free-standing oil-filled radiator. We also offer a variety of heating options including wall-mounted radiators, underfloor heating and air conditioning.
