Basebox Building Specifications
Walls
Walls
Crafted in-house using pioneering eco-friendly materials, the panel walls consist of a thick 9mm white MDF board with 75mm thick eco-polymer foam insulation.
The exterior cladding is a treated recycled composite made from sawdust from the milling industry, primed for resistance against rot and decay.
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
Roofing
The garden building roofing is made with a thick 80mm insulated steel panel that is reinforced with a 1mm powder-coated steel.
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.
Glazing
Glazing
The glazing is made with Pilkington K Optiwhite’ extra clear’ double-glazed windows and doors that are hard coated, low-e, argon-filled, and fitted with a Planitherm layer and Swisspacer. This advanced technology ensures exceptional insulation and energy efficiency.
Guttering
Guttering
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.

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.

We’ll Come to You!

Affordable Garden Rooms
Are you looking to achieve your home improvement goals on a budget? Well, look no further than our affordable Basebox garden room.
Garden rooms can be easily affordable and a worthwhile investment if you’re looking in the right places—and that happens to be here at Green Retreats! With the right approach and clever strategies, you can have your garden room without breaking the bank.
Self-Build Garden Room
The cheapest way to build a garden room would be to opt for a self-build option. This removes added fees such as installation, resulting in a considerable saving. Our cost-effective garden room, Basebox, comes in a self-build option, making it an even cheaper garden room option.
Garden Room vs Conservatory
Starting at £1,180 per m2 for a spacious 4.6m x 3.6m Basebox, garden rooms prove to be a much more cost-effective solution than conservatories, single-story extensions, and loft conversions.
Because garden rooms can be fully installed in 2-5 days, they cut down on installation times compared to traditional home extensions, which reduces costs and time.
Explore Financing Options
Affording a garden room on a tight budget may seem challenging, but financing options are available to make it more manageable.
At Green Retreats, we offer 0% finance on our Basebox and Basebox+ garden rooms, which can help you spread the cost of your garden room over 24, 36 or 48 months without incurring interest charges.
What our customers say
We are so pleased to be top rated on Trustpilot
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.
