Built to Exceptional Standards

Every structure is constructed to TRADA certification — the highest standard in the industry.

Residential grade

Residential grade

Unlike mass produced garden rooms, the Sandringham is residential grade. Engineered to the same exacting specification as your home, which means that whatever you use it for – from an extra living room or a luxury home office to a sumptuous entertaining space – you can enjoy it in home-from-home comfort, all year round, year upon year.

Built to Last

Built to Last

The Sandringham is built to permanent residential building standards, including residential grade insulation . Every element is painstakingly selected for quality and longevity. We insist on the finest craftsmanship: traditional timber building methods, rather than cheaper SIPS (structural insulated panels).
