Launching at RHS Chelsea Flower Show 2026

Clad in natural Durlston Purbeck limestone, supplied by Allgreen, the Purbeck is not a garden room in the conventional sense. It is a stone building. Built on a structural steel frame and finished with hand-formed lead and cedar shingle, it is designed to last not years but generations.

The same pagoda roofline and Zinc Artichoke detailing that define the Sussex are here but its set against natural stone, the effect is categorically different. 

Every Purbeck is built to order for clients for whom the garden building is not an afterthought but a centrepiece. The limestone is hand-fixed on a bespoke steel frame, the lead is formed on site, and the same considered approach to proportion and detail runs from the ridge finial to the skirting boards. Whether the finished building becomes a stone-walled office, a private entertaining pavilion or a garden retreat as permanent as the house beside it.

Fully insulated and weatherproofed for year-round use, the Purbeck can be dressed with slim-frame aluminium bifold doors and feature windows, each specified to your design at survey.
