Sustainable Architects in Eton | CSK Architects
CSK Architects is a thoughtful, ambitious practice dedicated to crafting tailored architectural designs that harmonise with historical and environmental contexts. With over three decades of experience, we specialise in contemporary architecture for sites of cultural and ecological significance, including listed buildings, Green Belt areas, and Conservation Areas. Our holistic approach integrates environmental sustainability across all stages of a building's lifecycle, from material selection to disassembly strategies. We have earned recognition for design excellence, including RIBA awards and a Stirling Prize shortlisting, while maintaining a strong focus on client satisfaction through pragmatic, resourceful project delivery.Our team of 12 architects ensures director-level involvement in every project, supported by long-standing relationships with consultants and contractors. Through initiatives like CSK RECLAIM, we pioneer circular economy practices by repurposing materials, and our research collaborations with institutions like UCL advance bio-renewable construction methods. This combination of heritage expertise, innovative sustainability practices, and client-centric service delivery positions us as leaders in regenerative architectural design.

Services
Retrofit at Home
We transform residential properties through deep retrofitting and sensitive renovations that preserve historic character while enhancing energy efficiency. Our approach combines traditional craftsmanship with modern sustainability techniques to create unique living spaces that respect architectural heritage. Each project receives tailored solutions that address both immediate needs and long-term environmental impact.
Retrofit at Work
Specialist retrofit solutions for historic commercial buildings and educational institutions requiring listed building consents. We navigate complex heritage regulations to deliver modernised spaces that maintain architectural integrity while meeting contemporary functional requirements. Our expertise includes working with London Estates, universities, and conservation bodies to extend building lifecycles sustainably.
New Building Lifecycles
Designing carbon-conscious new buildings that consider full lifecycle impacts from material sourcing to potential disassembly. We prioritise materials that minimise environmental impact while creating spaces that harmonise with natural ecosystems. Our approach integrates renewable energy systems and circular economy principles to create future-ready architectural solutions.
CSK RECLAIM
Our dedicated material reclamation initiative salvages and repurposes construction materials to reduce waste and create distinctive architectural elements. We systematically assess existing buildings as material resources, identifying opportunities for reuse within projects or across our portfolio. This practice creates unique design features while significantly reducing the environmental footprint of new developments.
Interior Design
Integrated interior design services that ensure cohesive vision from concept to completion. We create functional, aesthetically coherent spaces that reflect the building's character while meeting modern living requirements. Our approach considers material sustainability, spatial efficiency, and sensory experience to deliver interiors that enhance both form and function.
