The LABC Building Excellence Awards have long been established as the premier accolades within the industry; recognising the companies and individuals that demonstrate a commitment to competence, quality and standards in delivering safe and sustainable buildings for the communities we live and work in.
Over 800 individuals from across England and Wales, came together on 23 January 2026, showcasing the amazing people and projects working in our industry.
LABC is delighted to announce that the WINNER of the Best Residential Conversion or Alteration to an Existing Home is Old Gwernyfed, Powys.
The restoration and extension of Old Gwernyfed, a Grade I listed manor house in Powys, has transformed the remains of a 17th-century wing into a contemporary living space. The project involved glazing the entire end of the existing ruin and installing a bespoke glass and oak staircase, blending modern design with historic character. The scheme protected the ancient monument while creating a unique home that exceeded client expectations and was completed in time for a special family occasion.
Powys Building Control provided outstanding professionalism, local knowledge and technical expertise on a complex two-year project. Exceeding minimum standards, the extension connects to a biomass heating system and uses sustainable materials such as woodwool boards, sheep’s wool insulation, and hemp lime plaster. This collaborative approach ensured compliance, safety, and exceptional craftsmanship on a highly sensitive restoration.
The judges praised this project for its sensitive approach to restoring a historic building.
“This stunning conversion creates an extraordinary living space, with the entire end of the existing ruin glazed and a bespoke staircase made from glass and oak. Due to the sensitive nature of this Grade I Listed building, implementation of building regulations had to be applied with care and due diligence to avoid compromising the ancient fabric.”
