🏆Congrats to Old Gwernyfed, Powys.

National Winners! 🎉

We are delighted to announce that our project Old Gwernyfed, Powys has been awarded as the National Winner in the Best Residential Conversion or Alteration to an Existing Home category at the LABC Grand Finals 2025!

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.”

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.

We had a truly special evening celebrating.

Thank you to everyone who worked on this wonderful project with us and of course the clients, for trusting us with their vision for Old Gwernyfed.

LABC Wales Winner - Best Residential Conversion / Alteration to an Existing Home.

Jenkinson Builders are extremely proud to have been part of this acclaimed project where Medieval history has met the present day.

In Circa 1750 the South Wing of this Grade 1 Listed Old Gwernyfed Manor House suffered a catastrophic fire. Resulting in the wing becoming a ruin until 2022, when Jenkinson Builders were commissioned to undertake this multifaceted project.

The work was carried out under a strict archaeological brief due to the historical importance of the land. We implemented many different traditional trades ranging from;

- Stone carving to repair the stone mullion windows
- Traditional leaded lights and casement windows
- Careful restoration to existing stone walls using lime mortar matched to existing

The clever design brief from was to showcase by contrast, the original stonework with a modern frameless glass facade standing at an impressive 11.5m high, skilfully installed by

J A Francis of Knighton also provided structural steel to form the mezzanine floors and impressive roof structure enabling three new internal floor levels with maximised natural light and outward views.

Jenkinson Builders would like to extend this congratulations to the whole project team and of course a huge thanks to the clients to bring about this magnificent transformation.

Thank you for sharing the finished photographs.

We look forward to the National LABC Grand Finals in early 2026...
