Quality Materials & Design:

Basebox delivers a high-quality garden room solution. Sourced and selected components are known for their strength, resilience, and aesthetic appeal. From the robust framework to the weather-resistant cladding, every element is chosen carefully to ensure long-lasting quality.


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: 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: 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: 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: 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.
