Installed Green Retreats Basebox Garden Room 4.2m x 3m

• Product Specification

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.

Doors and Windows 

The doors and windows for the Basebox range are very strong steel-reinforced uPVC in a stylish  graphite woodgrain finish. The locks on the doors and windows are insurance-grade multi-locks,  keeping your building and its contents safe and secure. 

Glazing 

All windows and doors are fitted with Pilkington K Optiwhite extra-clear double glazing. This  advanced glazing features hard-coated, low-e, argon-filled glass with a Planitherm layer and  Swisspacer, ensuring excellent insulation and energy efficiency. 

Walls 

Our wall sections are crafted in-house using innovative eco-friendly materials. They feature a 9mm  thick white MDF board with 75mm thick eco-polymer foam insulation for excellent energy  efficiency. The exterior cladding is made from a treated recycled composite, sourced from sawdust  in the milling industry, which is primed to resist rot and decay. Please note: the exterior cladding of  this design will require painting to seal it within the first 6 months, which is a great opportunity to  personalise your building to suit your style. 

Flooring 

The Basebox subflooring is elevated above ground level to prevent rising damp and promote air  circulation. The flooring itself is a dense 80mm polyurethane insulation, supported by a 1mm  powder-coated steel layer on both the top and bottom, protecting the flooring from all weather  conditions and keeping it exceptionally strong. 

Roofing 

The roof is constructed with a thick 80mm insulated steel panel, reinforced with a 1mm powder coated steel layer. For added strength, a 0.5mm galvanised steel sheet reinforces the panel. The  roof's slightly sloped design allows for effective water runoff to the rear guttering system and  downpipe. 

Guttering 

Our 4-inch wide guttering system effectively manages excess water flow, helping to protect the  building structure.
