Sustainable Architects in Eton | CSK Architects
CSK Architects is a thoughtful, ambitious architectural practice dedicated to crafting tailored designs that create buildings with a profound sense of belonging. Our holistic approach to environmental design examines every stage of a building's lifecycle, combining contemporary architectural excellence with a regenerative environmental ethos. With over three decades of experience, we specialise in delivering high-quality contemporary buildings within historically significant locations, including Grade I, II, and II* listed buildings, Areas of Outstanding Natural Beauty, and Green Belt sites. Our team of 12 architects ensures director-level involvement throughout every project, leveraging deep expertise in listed building consents and complex planning applications.We pioneered the Cork House project, shortlisted for the RIBA Stirling Prize in 2019, which redefined modern building envelopes through sustainable materials. Our CSK RECLAIM initiative actively sources and integrates reclaimed materials into projects, aligning with circular economy principles. We maintain strong working relationships with consultants and contractors to deliver projects within programme and budget while maintaining exceptional quality standards.

Services
Retrofit at Home
We create exceptional residential spaces through deep retrofitting and sensitive renovations. Our approach preserves historic fabric while implementing modern sustainability standards. Projects range from large extensions to subtle upgrades, always focusing on transformative outcomes that respect the building's heritage and environmental impact.
Heritage Conservation
Specialists in listed building consents and historic preservation, we navigate complex heritage requirements. Our expertise covers Grade I, II, and II* listed buildings, Green Belt developments, and Areas of Outstanding Natural Beauty. We deliver adaptive reuse solutions that maintain architectural integrity while meeting modern functional needs.
Sustainable Design
Our whole-life approach to environmental sustainability considers embodied carbon and operational energy. We implement low-carbon materials, circular construction principles, and renewable energy strategies. The Cork House project exemplifies our commitment to net-zero carbon solutions and regenerative design practices.
CSK RECLAIM
This initiative focuses on sourcing and utilising reclaimed materials in architectural projects. We curate salvaged elements from our own sites and industry networks to create unique spaces. Our approach combines environmental responsibility with distinctive design character through repurposed materials that tell a story.
New Building Lifecycles
We design new buildings that consider their entire lifecycle from construction to potential reuse. Our approach examines material systems and assembly processes to ensure disassembly and recycling possibilities. Projects incorporate bio-renewable materials like hemp and stone reuse strategies to create buildings that harmonise with natural ecosystems.
