Start to finish.

Every project begins with a conversation about your home and the feeling you want from it. From there, we take care of everything; designing to your vision, delivering on time and on budget, leaving you free to simply look forward to the result.

Behind every project is a team of specialists we have worked with for over a decade. People we trust completely, because our clients' homes deserve nothing less.

We bring the vision, the expertise and everything in between.

The result is a room that works completely. Not just for now, but for the way your life actually looks in ten years' time.

Our services

"The moment I met Fiona and Alice I knew they were “The Dream Team” Their ability to grasp our needs when renovating our Grade 2 cottage in Esher was quite remarkable. The mood boards / visuals showcased at the beginning of the process were invaluable and took away any doubts regarding how the cottage would look when finished. They were hands on from day one, with such an easy going attitude but at the same time totally professional and committed."

— DIANE

Fiona really listened to what we wanted and communicated any ideas and changes to us which made us feel really confident. Professional and friendly from the first meeting, would happily recommend.”

“We are delighted with the beautiful space that Fiona designed for us. From the very first meeting we felt that we were in safe hands, with someone who understood who we were and how to translate that into a beautiful, yet practical design. Fiona’s communication with us and our builders made the entire process easy. We couldn’t be happier with the result.”

“I loved every part of the process. Fiona designed the place to exactly what I wanted; modern, chic, stylish & practical, with perfect choice of colours in both bedrooms and the living room. So I can’t thank her enough. Fiona is simply fantastic in what she does and I will definitely come back to her for any other projects I may have in the future.”

"Having moved in to a new build house in Esher, we were looking for someone to transform a lovely, empty box, into a special family home. We couldn't have wished for any more with Fiona and her wonderful team. The 'home makeover' has been effortless; certainly the best money we have spent in the moving process."

A large vase with green and cream hydrangeas sits in the center of the table. There are three wooden chairs at the table and a person walking past, blurred due to motion.

About The Studio

Our Work

There is a thread that runs through everything we design. Spaces that feel calm and uncluttered, with depth, warmth and a real attention to light and detail. But within that, no two rooms look the same because no two clients are the same.
