How We Work

Granit is an award-winning architecture and interior design practice. We provide a bespoke design service for people who want to create a beautiful home that reflects their style and tastes.

Our clients often find basement conversions or extension works can be overwhelming, or they don’t know where to start.

Our team has over 30 years of experience designing beautiful homes, including basement design and everything else from side returns and extensions, to specifying kitchen and bathroom details and interior design. You can see some testimonials from our many satisfied clients here.

We combine a deep knowledge of architecture, working with people, space, light and modern interior design principles to create basement design and homes our clients love. This expertise is especially important in basement conversions where there are additional complexities with planning permission and creating light, dry and spacious accommodation.

Who you will be meeting

Our architecture team is led by Robert Wilson and James Munro, who collectively have over 50 years of architectural and basement design experience. They work closely with our interior design team too, which enables them to look at a project holistically and from every aspect.
