Sell + install premium garden rooms and studios.

As a garden room installer, your day-to-day involves sourcing materials, coordinating with manufacturers, and managing installations. You'll liaise with clients to understand their needs, provide quotes, and oversee the construction process, ensuring quality and adherence to timelines. Marketing efforts will include local advertising and networking with landscapers to generate leads. Building a show garden can showcase your work and attract potential customers, enhancing your credibility.

The demand for garden rooms has surged, fuelled by remote working trends and the need for additional space. With more people seeking home offices, studios, or leisure spaces, now is an ideal time to enter this market. Government incentives for green building practices may also bolster interest in sustainable, high-quality garden rooms.

Ideal founders will have a background in construction, project management, or sales. Expect to invest significant time in building relationships with suppliers and customers, as well as managing the installation process. Realistically, you should prepare for 20-30 hours a week, increasing as your business grows. The initial learning curve can be steep, especially in mastering installation techniques and understanding customer preferences.

Within 12-24 months, a successful garden room installation business could see revenues between £100k and £200k. If you establish a strong reputation and efficient processes, there’s potential for profit margins of 20-40%. Expanding your service offerings or targeting different client segments can further enhance your financial outlook.
