“Decorative finishing has always been about far more than applying paint. For me, it’s the careful use of materials, colour and texture to enhance the character of a space and bring balance to the architecture of a home.
With more than twenty years in the craft, every project is approached with the same attention to preparation, materials and detail. Whether working with natural lime washes, decorative plasters, specialist wallpapers or fine spray finishes, the aim is always to create surfaces that feel refined, timeless and quietly distinctive.
Many of the finishes I work with are applied by hand and built up in layers, allowing subtle variation in tone and texture to develop naturally. This process gives walls and architectural features a depth and character that simply cannot be achieved with conventional decorating methods.
When done well, the finish doesn’t sit on the surface of the home – it becomes part of the design itself.”

Working with designers, architects and homeowners
Projects are often undertaken in collaboration with interior designers, architects and private homeowners seeking carefully considered decorative finishes.
Work may range from a single feature wall to complete interior schemes, always approached with attention to detail and respect for the design of the property. Preparation, material selection and application are managed carefully to ensure the final finish sits naturally within the architecture of the space.
A considered approach to materials and surfaces
Many of the finishes used are based on traditional or mineral materials that have been valued in architecture for centuries. Lime washes, clay plasters and other natural coatings create surfaces that breathe, age gracefully and develop a soft, tactile character over time.
Alongside these traditional techniques, modern finishing systems such as spray application allow cabinetry and joinery to be finished with exceptional precision.
Together, these methods provide a wide range of possibilities for creating distinctive interiors.
