What’s included v See Specification v
The B1 is a modern cabin style building with a visibly sloping roof and front hood for a sheltered, traditional feel.
The B1 was the very first design in the B-Range, formerly known as Basebox. Originally introduced as a single style range, its popularity led to the development of four additional designs built using the same cost effective materials and streamlined construction process.
The B1 has a distinctive cabin inspired look, created by a sloping roof that runs from front to back and is visible from the sides of the building. At the front, an extended hood forms a small sheltered entrance, enhancing the traditional feel while adding a practical touch. It also includes a 1.8m French or sliding door, LP Strongcore cladding, a lozenge window, and a durable melamine interior finish, combining classic design with practical, high quality materials throughout.
One composite decking board sits at the front of the building, providing both a smart finishing detail and a useful step into the space. This small platform helps create a neat, polished look, particularly on slightly uneven ground, while making access into the building comfortable and easy.
If you are drawn to a garden room with a more traditional cabin style character, the B1 is a natural choice.

The 4″ wide guttering further ensures the longevity of your garden pod by effectively managing excessive water flow, preserving the pod’s structure so you can enjoy it no matter the weather.
Flooring
Flooring
The flooring is designed to prevent any potential dampness from rising by promoting air circulation.
Additionally, the garden building subflooring sits above the ground level to further ensure this. The 80mm polyurethane insulation is supported by a 1mm powder-coated steel on both the top and bottom to keep the flooring protected against all-weather types.
Roofing

For further structural integrity, the roof has an added 0.5mm galvanised steel sheet to reinforce the panel. The roof’s design is slightly sloped, enabling effective water runoff to the rear guttering system and down-pipe.

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.

How to buy…
Simply place your £300 holding deposit to secure an installation date any time in the next 12 months.
This deposit is fully refundable up until six weeks before your chosen installation date, and you can continue to make amendments to your design right up to 6 weeks before too.
Payment Schedule & Finance Options
£300 Holding Deposit
Due: At any early stage of your planning
Your £300 holding deposit secures your installation date and locks in your quoted price for 1 year from the date the order is placed. It’s fully changeable and refundable up until 6 weeks before your installation date – giving you complete peace of mind while you finalise your plans.
60% Building Deposit
Due: 6 weeks before installation
We require confirmation of your building 6 weeks prior to installation. At this point, a 60% deposit is due, which secures your order and sends your building into production. This step ensures everything is ready and on track for your scheduled installation date. No further changes can be made after this payment has been taken.
30% of Remaining Balance
Due: On final day of initial construction
It typically takes 2–5 days to install your garden room. On the final day of this initial construction phase, we require 30% of the remaining balance. This payment confirms completion of the main building structure and allows us to proceed with the finishing touches such as electrics.
Final 10% of Remaining Balance
Due: On full building completion
After the main structure is installed, final works such as electrics, plastering, and any optional extras like air conditioning will be completed. Once these finishing touches are done, the remaining 10% balance is due. At this point, your 12-year guarantee is also activated, giving you complete peace of mind.
