Architecture
We specialise in designing extensions that seamlessly integrate with historic buildings while creating bespoke new-build houses that respect their surroundings. Our RIBA Chartered team handles planning applications, listed building consents, and detailed construction drawings. With over 30 years' experience, we combine traditional architectural principles with modern sustainability requirements to deliver projects that satisfy both clients and conservation officers.
Interior Design
Our in-house interior designers specialise in period-appropriate renovations while incorporating modern functionality. We create detailed room schemes, material boards, and joinery specifications that maintain historical authenticity. From colour palettes to bespoke fittings, our team ensures interiors reflect both the building's heritage and the client's lifestyle requirements while maintaining compliance with conservation standards.
Eco Design
As members of The Green Register, we integrate low-carbon technologies and natural materials into both restoration and new-build projects. Our eco-design approach includes renewable energy systems, sustainable construction methods, and locally sourced materials. We balance environmental considerations with heritage requirements to create energy-efficient buildings that maintain historical integrity and reduce environmental impact.
Conservation
Specialists in working with listed buildings and historic structures, we understand the complexities of preservation requirements. Our Accredited in Building Conservation (AABC) status ensures expert navigation of planning regulations while maintaining architectural authenticity. We employ traditional craftsmanship techniques alongside modern solutions to protect and enhance historic properties for future generations.
Barn Conversions
We transform historic agricultural buildings into functional residential and commercial spaces while preserving their character. Our approach balances modern living requirements with conservation principles, ensuring compliance with planning regulations. From initial concept to completion, we manage all aspects of barn conversion projects, incorporating sustainable materials and energy-efficient systems where appropriate.
