“We used WK to design and manage the building of a glass and steel garden room extension to our Grade II Listed house. Their professionalism was exceptional and the finished space is fantastic.”

Preserving the character of the vast East Anglian countryside, home to over 55,000 listed buildings and 1,200 Conservation Areas, is integral to our work as conservation architects. We have over four decades of experience in adapting old buildings while preserving their heritage, collaborating with historic building experts, landscape architects, and local authorities to ensure thoughtful and respectful designs.
We approach architectural projects of this style with imagination and sensitivity, offering energy-efficient solutions that honour the building’s past while enhancing it for the present.
A preservation architect brings specialist insight to historic buildings, ensuring their architectural and cultural significance is understood before change is considered. Demanding a careful and considered balance between protection and progress, heritage projects need informed guidance to ensure the building continues to serve a purpose without losing those special historical qualities that define their character.
On our team sit several architects with heritage and restoration skillsets, and they proudly thread the building’s existing history and environmental setting throughout our conservation projects. This understanding allows for sensitive repairs, adaptations, and additions that respond to modern needs while remaining true to the building’s personality.
A heritage architect’s experience and knowledge of conservation-led design means clients are offered confidence and transparency throughout the complexities of these projects, from navigating regulations and approvals to finding harmony between the past, present, and future. We engage early with local authorities and statutory bodies, and prioritise open communication to reduce the chance of risks and avoid frustrating delays.
The resulting architecture from this care and dedication respects the past while allowing for beautiful, historic buildings to continue contributing meaningfully to their surroundings and the community.
Heritage buildings are so much more than just old structures; they are records of local history, traditional craftsmanship, and identity. At Wincer Kievenar, we understand and respect the responsibility that comes with working on these historic assets. We root our approach to these special projects in sensitive design, intensive research, and practical solutions that protect heritage value while ensuring the buildings remain relevant today.
