"Working with Melissa and the team at Andrew Catto Architects has been the key to delivering our building project. Without her expertise and direction, we feel our space would not be half as inviting and flow so well. She works hard to timelines, and importantly provides creative inspiration to make the space work so much better. She is committed, fun to work with and understands budget limitations. She has considerable technical expertise with builds and her project management techniques are fantastic."

“I can thoroughly recommend Andrew Catto and his team. We undertook a large side return and extension project in Putney and their professionalism and attention to detail throughout made the whole process go through seamlessly. From Andrew’s initial meetings and careful plans through to Melissa’s excellent management of the project it was a top rate service, with great levels of client care”.
