SI&CO is a London based architecture and interiors studio specialising in residential refurbishments with character, alongside selected hospitality projects.

​

We work with clients who want spaces that feel considered and individual, approaching each project through architectural thinking rather than a fixed aesthetic. Our work focuses on clarity of space, proportion, materiality, and detail, creating environments that are refined, functional, and enduring.

​

Our projects are best suited to clients seeking thoughtful, non traditional refurbishments rather than conventional period pastiche. Alongside residential work, SI&CO undertakes a limited number of hospitality projects where atmosphere and spatial identity are central.
