DESIGN
DIRECTOR
I’m Siân Denné, an architectural and interior designer with a passion for narrative and craftsmanship. I create spaces full of character and purpose, blending creativity with a meticulous eye for detail.
My role at Imagination has taken me around the world, designing for iconic luxury brands on global projects. I craft evocative, meaningful spaces for clients who value clear vision, bold ideas, and uncompromising attention to detail.
I’m currently working on architectural designs, art exhibitions and interior projects across Europe and the United States, splitting my time between London and Marlow.
WORKING WITH ME, WHAT YOU CAN EXPECT.
A calm, considered design process, for people looking for thoughtful, original and beautifully made spaces - without the stress.
-
From concept to completion - design, sourcing, logistics, and installation, are all handled through a trusted network of top-tier makers and builders.
-
Streamlined communication from start to finish. No middlemen, no misalignment, just a single, dedicated lead overseeing every detail.
-
No overwhelming options. Just carefully tailored ideas and clear, confident direction, so you can make decisions with ease.
-
Backed by years designing for luxury brands, each space is approached with fresh thinking, turning constraints into standout features.
-
A space should work, not just look good. With an architectural background, I plan with flow, proportion, and purpose in mind.
-
I collaborate with artists and craftspeople to design custom furniture, lighting, joinery, and artwork that bring individuality to your space.
-
Having worked with global brands like Rolls-Royce and private clients around the world, I bring a calm, discreet, and detail-driven approach to every project.
-
Whether it’s a home, a brand space, or a full renovation, the approach adapts to the project’s needs, always grounded in clarity, care, and design integrity.
