From home offices to music studios, garden gyms to annexes — here are the most popular and practical ways UK homeowners are using their garden rooms.
The Best Uses for a Garden Room in 2025
Garden rooms have evolved significantly from simple summerhouses. Today's garden rooms are fully insulated, year-round spaces that can serve almost any domestic purpose. Here are the most popular uses — and what each one requires.
1. Home Office
The most popular use by far, driven by the shift to remote and hybrid working. A dedicated garden office separates work from home life, improves focus, and provides a professional environment for video calls.
What you need: Good insulation (year-round comfort), reliable power and data connectivity, adequate lighting, and a heating system. Consider acoustic treatment if you're on video calls frequently.
Typical size: 3m × 3m to 5m × 4m
2. Art Studio or Creative Space
A garden studio provides natural light, space to spread out, and the freedom to make mess without worrying about the house. Popular with artists, photographers, potters, and crafters.
What you need: Large windows or roof lights for natural light, good ventilation, easy-clean flooring, and a utility sink if you're working with wet materials.
Typical size: 4m × 4m to 6m × 4m
3. Garden Gym
A home gym eliminates gym membership costs, commute time, and the self-consciousness of exercising in public. Garden gyms are increasingly popular as people invest in their health and wellbeing.
What you need: Rubber flooring (to protect the structure and reduce noise), good ventilation (gyms generate significant heat and moisture), mirrors, and adequate power for equipment.
Typical size: 5m × 4m to 7m × 5m
4. Music Room or Recording Studio
A garden music room provides the acoustic separation needed to play or record without disturbing the household or neighbours. Acoustic treatment is important but doesn't need to be expensive.
What you need: Acoustic insulation (mineral wool is good for this), acoustic panels or treatment on walls, adequate power for equipment, and good cable management.
Typical size: 4m × 4m to 5m × 5m
5. Relaxation Room or Garden Bar
A dedicated relaxation space — whether a reading room, meditation space, or garden bar — provides a retreat from the house. Garden bars have become particularly popular.
What you need: Comfortable heating, good lighting (dimmable is ideal), bi-fold or sliding doors to connect with the garden, and a sound system if it's an entertainment space.
Typical size: 4m × 3m to 6m × 4m
6. Garden Annexe
A garden annexe is a fully habitable space that can accommodate overnight guests, elderly relatives, or (with planning permission) be rented out. This is the most complex and expensive type of garden room.
What you need: Full insulation to habitable standard, a WC and shower (requires building regulations), a kitchenette, and potentially separate planning permission if it's to be used as a separate dwelling.
Typical size: 6m × 5m to 8m × 6m
7. Children's Playroom
A dedicated playroom keeps toys and mess out of the house and gives children a space of their own. As children grow, the room can be repurposed.
What you need: Good insulation (children need warmth), safety glazing, underfloor heating (safer than radiators for young children), and easy-clean flooring.
Typical size: 4m × 3m to 5m × 4m
8. Therapy or Treatment Room
Garden rooms are increasingly used by therapists, counsellors, and beauty therapists as a professional treatment space. This provides separation between home and work and a professional environment for clients.
What you need: Good soundproofing for confidentiality, a separate entrance if possible, a WC nearby, and appropriate heating and lighting.
Typical size: 4m × 3m to 5m × 3m
Choosing the Right Use
The best garden room use is the one that genuinely improves your daily life. Before committing to a specification, ask yourself:
- How often will I use this space?
- What are the specific requirements (power, data, plumbing, acoustics)?
- Will my needs change in 5–10 years?
- Is this the best use of my budget?
