I spent quite a lot of time researching options for a garden office before finding Garden Affairs, their solutions fitted my requirements perfectly and opted for the midi office. There are similar suppliers a bit more local, but I opted for Garden Affairs specifically because they weren't just builders, but delivered impeccable customer service and experience.
They guide you through the journey and advised what the best options were, this was critical for my project as their deep knowledge of how to approach specifics helped me to take the right decisions. They clearly explained potential challenges such as delivery and how to mitigate them. Their website and the team provide plenty of useful information on how to plan, maintain, approach electrics, planning permission and so on which was useful.
They built the office exactly to specification and was exactly how I envisioned it. The team are friendly, responsive and helpful and would recommend them to anyone interested in a customised garden office.
