B1 introductory price starting from £11,235

Green Retreats has launched the new B-Range, expanding its popular Basebox garden room into a wider range of five distinct designs. Created in response to growing demand for simpler, cost-effective ways to add space at home. Starting from £8,235, B-Range builds on everything that made Basebox so popular while offering customers more choice in style and layout.

“Basebox showed us there was a clear appetite for a more straightforward, cost-conscious way to create extra space at home.” says Roy Wetherall, Managing Director of Green Retreats. “With B-Range, we’ve responded to that demand by expanding the range, giving customers more options while keeping the same simple, accessible approach.”

About The B-Range


B-Range offers an accessible route to owning a fully insulated garden room. Designed as an alternative to traditional home extensions, the range focuses on efficient construction, streamlined specifications and carefully selected materials, while still delivering the performance needed for year-round use.


B-Range buildings are suited to a wide variety of uses, including garden offices, home gyms, studios and additional living space. With professional installation available, they provide a practical way to add space at home with minimal disruption.

Designs within the B-Range


The B-Range includes five designs, each offering a slightly different look and feel to suit different gardens and preferences: 


·     B1 features a cabin inspired design, with a visible sloping roof and sheltered front that creates a more traditional and characterful appearance.


·     B1 Lite offers a simplified version of the original B1, with a more pared back specification for those prioritising affordability.


·     B2 has a compact, modern pod style design, ideal for smaller gardens or tighter spaces.


·     B3 brings a more architectural look, with sharper lines and a bold, structured frame.


·     B5 stands out with its distinctive curved corner, giving it a softer and more contemporary edge.


Each design is available in a range of sizes and can be tailored to suit different uses, from a dedicated garden office to a flexible, multi-purpose space.
