What’s included v See Specification v
The B5 is a modern, squared form distinguished by a signature curved corner, blending a sheltered hood with an enclosed side cheek.
The B5 is ‘the curve’, a distinctive twist to the B-Range with a design that blends modern squared lines with a softer architectural curved corner feature.
The signature curved corner sets it apart from the rest of the range, creating a smooth transition between the front and side of the building. This curved detail adds visual interest while maintaining the clean and contemporary shape of the overall design.
The B5 design incorporates a hooded front and a partially enclosed side, giving the building a slightly more private and protected feel at the front. It also includes a 1.8m French or sliding door, LP Strongcore cladding, a lozenge window, and a durable melamine interior finish, combining distinctive design with practical, high quality materials throughout.
If you are looking for a modern garden room with a unique design feature that stands out from the crowd, the curve of the B5 is the perfect choice for you.

B-Range Optional Upgrades
Our B-Range optional upgrades give you the choice of how hands-on you’d like to be with your garden room project. Add them on if you’d like us to take care of everything, or leave them off if you’d prefer a more DIY approach. It’s all about making the build work your way and to your budget.
Foundations
A level ground and a suitable foundation is required for your B-Range building.
Opting for our foundations upgrade will see our teams create a stable base of ground screws for your building without you having to do it yourself or find a local tradesperson.
As with all our ranges, you must prepare the ground before we arrive to be clear and level within 200mm.
Laminate Flooring
Upgrade to have a professionally fitted laminate floor installed in your garden room.
Available in:
- light oak
- grey oak
- dark oak
The flooring is designed for a neat, durable and low-maintenance surface that complements the interior of your B-Range.
DIY Paint Kit
The DIY paint kit provides everything you need to paint the exterior cladding in your chosen colour.
Supplied with a choice of modern black, smokey grey or chic sage green, the paint is ready for you to apply yourself. The B-Range cladding must be painted with outdoor paint within six months of installation to protect and preserve the building.
Alternatively, upgrade to have the uPVC wood effect vinyl cladding fitted at an extra charge for a maintenance-free, colour-stable finish.
Internal Electrics
Upgrading to internal electrics for the B-Range adds power and lighting to your garden room which is installed by our trained team.
It includes 2 surface-mounted double sockets, 1 panel light, a consumer unit, and a 1.5kW oil-filled standing radiator.

by our customers.
by Louisa (Louisa Tudor)
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.
by Peter
Can’t beat a Green Retreat!
We cannot recommend Green Retreats highly enough, compare their offer to anyone else and I think they will win the day. The finished result is a garden room of class and something to be proud of. Value is what you get as an overall package and experience, not what just the price tag states. Choose low maintenance materials and you cannot do better than Green Retreats, they simply are very hard to beat!
by Mark
I’d recommend them to anyone
Each element of the team that came were all extremely polite, punctual and very professional. The quality of the materials are extremely high and the overall quality of the garden room is amazing. It’s fabulous to be able to sit in a room outside to work and to relax and enjoy the garden to its full potential. Green Retreats have been superb throughout the process, and we would not hesitate to recommend them to anyone!
by Sarah Levin
What a great company!
The customer care and communication, from the start of my enquiry through to the installation has been exemplary! I’m so pleased with my G2, it not only looks great but it is a
first class product down to the last detail. I can’t recommend Green Retreats highly enough and I’m super excited to relocate my art studio into the garden! Thank you Green Retreats.
