Interiors with colour, character and soul.
Interiors that feel as good as they look.
I’m Siobhan Casey, founder of Casey & Fox, an interior design studio based in Sanderstead, South London. I create colourful, characterful homes for people who want their interiors to feel personal, layered and completely their own.
I work with homeowners across South London, Surrey and beyond, from single-room transformations to full home refurbishments.
Your home doesn’t need to be perfect. It needs to feel like you.
I love interiors with personality. Rooms that mix old and new, colour and pattern, beautiful things and practical ones. Homes that feel collected over time rather than styled within an inch of their lives.
Whether you’re refreshing a single room or rethinking your whole home, I’ll help you make sense of the options and create something that feels right for the way you live.
For larger projects, my bespoke interior design services cover everything from layouts, kitchens and bathrooms to lighting, joinery, furniture and art. If you just need focused advice on one room or help with design decisions, my online consultations are designed for exactly that.
And if you’d like to see what all that looks like in practice, have a look through our project gallery.

Online Consultations
Stuck on a room, a decision or simply not sure what to do next?
Our online consultations give you direct access to expert interior design advice, whether you need help with colour, layout, lighting, furniture or a renovation dilemma. Practical, personal advice without committing to a full design project.
Bespoke Interiors
For larger projects, I’m with you from the first ideas to the final details.
Our bespoke interior design service covers everything from space planning, kitchens and bathrooms to lighting, bespoke joinery, furniture and art. The aim is simple: a home that works beautifully and feels unmistakably yours.
Stories of Happy Spaces
You know the room isn’t right. You just can’t see why.
The Design Hotline is for those moments when you know something isn’t working but you can’t quite see the answer. Maybe it’s the paint colour, the layout, the lighting, the furniture, or one decision that’s holding everything else up.
Send me the problem in advance and we’ll use the session to get you unstuck, with practical, personalised advice you can actually put into action.
Ideas, advice and a few things I’ve learnt along the way
Practical interior design advice, renovation know-how and thoughts on creating a home that feels more like you.
