The Opulence
The Opulence is one of our most popular models, offering a sleek and modern garden room that combines clean design with year round comfort. With large glazed fronts and natural finishes, it creates a bright and versatile space that blends perfectly with its surroundings.

Insulated splines for strong, airtight joins

C16/24 treated timber for all structural edges and frames
