Our talented interior designers create timeless spaces with a commitment to sustainable design and quality craftsmanship. From full-scale spatial rearrangements to bespoke joinery design, the studio has the ability to breathe new life into any space.

Interior Architecture

The studio creates innovative spacial design by reconstructing or reshaping interior spaces to enhance rooms and maximise their use. Projects include listed buildings, restorations and refurbishments. Our specialist team provide detailed technical drawings and work closely with contractors to ensure the highest standard is realised.

As well as existing spaces our team can also advise on extensions, basements, loft conversions as well as new build interiors to increase their potential and purpose.


Our furniture, fittings and equipment (FF&E) team further develop the interior design scheme. Our clients are always at the forefront of each project, therefore we are meticulous in selecting local suppliers and artisans to source contemporary pieces, artworks, one-of-a-kind antiques and custom-made furniture. Our aim is to make each space authentic and truly special to the client.
