7m x 5m contemporary garden annexe
Three parts to a 35sqm footprint — a living space with an L-shaped kitchen, a double bedroom, and a shower room bigger than most annexes get.
Executive Garden Rooms designed and built this 7m x 5m contemporary garden annexe, a striking addition to their extensive portfolio of self-contained garden homes. This annexe has been thoughtfully designed to provide a comfortable and light-filled living space for one person.
At a glance
- Size: 7m x 5m, divided into three — a generous living space with an L-shaped kitchen, a double bedroom, and an en-suite shower room.
- Who for: designed as a comfortable, light-filled home for one person.
- Foundations: traditional reinforced concrete rather than the pads some companies use — more groundwork, more long-term stability.
- Also below ground: a pumping station and the piping to connect the annexe to the mains.
- Light: a corner run of floor-to-ceiling glazing in the living space — French doors flanked by large windows whose upper sections open. A smaller corner window in the bedroom keeps the privacy.
- Kitchen: high-gloss, with base and overhead units, inset hob, sink, electric oven, plumbing for a washing machine and an under-sink water heater.
- Warmth and wiring: insulated beyond new-build standards, heated by two electric wall panels; 18 recessed LED downlights, an external security light, two smoke alarms and hardwired Cat6.

Extensive groundworks and reliable foundations
Upon securing planning approval, the team begins on-site groundworks. This particular project required extensive groundwork preparation before construction could commence. Executive Garden Rooms favour traditional, reinforced concrete foundations for their annexes, offering long-lasting stability that many buyers prefer over the pad foundations used by other companies.
Additional excavations were also needed to install a pumping station and to lay piping for connecting the annexe’s utilities to the mains supply.
Bright and comfortable living space
The design brief focused on creating a spacious, one-bedroom home with ample natural light. The 7m x 5m annexe footprint was divided into three main areas: a generous living space incorporating an L-shaped kitchen, a double bedroom, and an ensuite shower room.
The high-gloss kitchen is well-equipped, featuring both base and overhead storage units, good work surfaces, an inset hob, and a sink. The kitchen also includes an electric oven and provisions for a washing machine, with an under-sink water heater ensuring instant hot water.
Natural light floods the main living area through a stylish corner section of floor-to-ceiling glazing, consisting of French doors flanked by large windows. The upper sections of these windows open for convenient ventilation.
In the bedroom, a smaller corner window setup allows for light while maintaining privacy. This thoughtful design leaves space for the bed and wardrobes.
The ensuite shower room is more spacious than typical annexe layouts and includes a large shower cubicle with a glass door, a washbasin set into a vanity unit, and a toilet.
Heating and electrical features
Compliant with Building Regulations, this annexe is insulated to exceed new build standards. However, heating is still necessary for colder days. For this project, two electric wall panel heaters were chosen to maintain a cosy environment.
The electrical setup includes numerous double power sockets strategically placed throughout the annexe, 18 recessed LED downlights, an external security light, and two smoke alarms for safety. Internet connectivity is assured through hardwired Cat6 data cabling.
