Building Regulations

Building Regulation compliant

Executive Garden Rooms designs their buildings as permanent structures, complying with Schedule 2 of the Building Regulations 2010. This 6m x 4m office is built to a high specification, including a spacious shower room powered by a 125-litre pressurised water system. The inclusion of a shower room means that the building could easily serve as a guest room or a more versatile living space in the future.

While building a garden office to full Building Regulation standards and including features like a shower room can increase the initial investment, it provides long-term benefits and greater flexibility, boosting both usability and potential house value.

Turnkey service

Turnkey service with complete project management

Executive Garden Rooms offer a comprehensive turnkey service, covering everything from initial design to final decoration. This includes managing all aspects of groundwork, from foundations to the installation of necessary utilities for the shower room. For this project, extensive groundwork was required, including a pumping station for foul waste, trenches connecting the building to the main house, and provisions for water, electricity, and CAT6 data cabling for reliable internet.

Shower room

High-pressure shower

The inclusion of a pressurised water system ensures a steady, strong water flow in the shower room, even when water is in use in the main house. This is a unique touch that Executive Garden Rooms incorporates into their designs, elevating the user experience and setting their builds apart.

The shower room and an adjoining airing cupboard are located at the rear of the building, maximising the main office space for a light, open layout. Executive Garden Rooms provides a fully plastered and decorated finish, ensuring a high-quality interior.

Exterior

Classic exterior design with Georgian-style French doors

The office exterior combines muted green-grey Cedral cladding with Georgian-style French doors in off-white, mirroring the style of the main house for a cohesive look. Cedral cladding is highly durable, low maintenance, and won’t warp or fade over time, making it ideal for a garden office. The Georgian glazing bars on the doors lend a traditional touch that softens the appearance, creating a timeless aesthetic.
