Air Conditioning & Heating for Garden Offices, Studios and Garden Rooms in London
Stay Comfortable in Your Garden Office All Year Round
Working or living in a garden office, studio, or annexe is one of the best ways to enjoy extra space at home. But these buildings often get too hot in summer and uncomfortably cold in winter — and because most only have electricity, traditional gas heating isn’t an option.
At Arcas Air Conditioning, we install compact, energy-efficient systems that provide both cooling and heating in one. Whether it’s a home office, gym, studio flat, or Airbnb annexe, our solutions keep you comfortable all year round — wherever you are in London.

Why Choose Air Conditioning for Your Garden Room?
- Year-Round Comfort – Cool in summer, warm in winter with a single unit.
- Energy Efficient – Cheaper to run than portable heaters or electric radiators.
- All-Electric – No need for a gas connection; perfect for outbuildings.
- Compact & Stylish – Wall-mounted or floor units that blend into small spaces.
- Quiet Operation – Ideal for home working, studying, or creative spaces.
- Healthier Air – Built-in filters improve indoor air quality for a fresher environment.
Perfect for Every Type of Garden Building
Our systems are ideal for:
- Garden Home Offices – Stay productive and focused, whatever the weather.
- Studio Flats & Annexes – Year-round comfort for you, family, or tenants.
- Airbnb or Rental Units – Add value with modern, efficient heating and cooling.
- Garden Gyms or Hobby Rooms – Work out or relax in comfort.
- Art & Music Studios – Maintain the right climate for creativity.

Installation Options
We offer a range of systems to suit garden buildings of any size:
- Wall-Mounted Split Units – The most popular choice for garden offices.
- Compact Floor-Mounted Units – Great for smaller or low-wall spaces.
- Multi-Split Systems – Control more than one garden room or area from a single outdoor unit.
Our expert engineers will survey your garden office, recommend the most efficient solution, and carry out a professional installation with minimal disruption.

“Arcas installed a compact system in our garden office in Richmond. It’s been a game-changer — warm through winter, cool in summer, and much cheaper than the plug-in heater we used before.”
