Siobhan

Kitchen & Fitted Furniture Design · 22 Years

“A great kitchen isn't designed to be admired from a distance. It's designed to be lived in, every single day — and that distinction changes every decision I make.”

With 22 years in kitchen and fitted furniture design, Siobhan has built her reputation on a simple conviction: the kitchen is the architectural heart of a home, and it deserves to be treated as such. Her process begins with how you actually live — how you cook, how you gather, how light moves through the space — and works outward from there.

Working with a select network of independent makers, Siobhan creates carefully considered kitchens tailored to both the home and the people living in it. Each project is guided independently, allowing greater flexibility in style, specification, and overall design outcome. For outdoor kitchens, she sources across the wider market to find the right solution for each space.

Outdoor Kitchens

The whole market — impartially

Modular · Bespoke · Contemporary

Siobhan approaches outdoor kitchens independently, sourcing across the wider market to specify the right combination of cabinetry, appliances, materials, and layout for each individual project. In addition to selected outdoor kitchen systems, she also designs bespoke outdoor kitchens tailored to the architecture of the home, the surrounding landscape, and the way the space will be used. The result is a more considered outdoor living space that feels cohesive, functional, and refined.

What clients say

In their words.

Kitchen

“Working with Siobhan was a fantastic experience from start to finish. The prospect of designing a kitchen and boot room in a listed property felt quite overwhelming, with wandering walls and lack of straight edges. From our very first meeting Siobhan fully understood the brief — to preserve the character of the property whilst maximising functionality.”

“Siobhan worked efficiently to (very) short deadlines and it was incredibly helpful to see rendered designs of the space before finalising any decisions. Siobhan's depth of expertise made the whole process from start to finish something I was able to enjoy rather than dread — thank you!”

“Siobhan at Decimus Design Studio did a wonderful job designing my kitchen as part of our new open-plan kitchen/diner extension. I wanted a handmade kitchen, but it was important to me to have an independent designer who could create something truly tailored to how I live, rather than being tied to a specific kitchen company.”

“Siobhan really took the time to understand what I wanted and needed, and guided me through aspects of how I'd actually use the space that I hadn't even considered. The result is a kitchen that not only looks beautiful but works perfectly for our day-to-day life.”
