The Opulence Hideout
The Opulence Hideout is a contemporary garden room that combines modern architecture with a warm and natural feel. Large glazed fronts fill the space with light, creating a smooth connection between the indoors and the surrounding landscape.
Designed for flexibility, it can be used as a home office, gym, art studio, cinema room, or luxury retreat, offering comfort, durability, and style throughout the year. Each Hideout is fully managed by our in-house construction team, providing a complete turnkey service from the first design to final installation.
