Glazing Vision’s Wall-abutted Flushglaze rooflight unlocked some much-needed natural light, enhancing old materials and highlighting modern additions for this award-winning extension and refurbishment in Sheffield.

The Hollis Building, formerly a Sunday school, now serves as a social space, housing facilities for both Channing Hall and the Upper Chapel. Chiles Evans + Care Architects were tasked with reorganising and modernising the space.

“The strategy was not to undertake a restoration project, but to unpick poor quality alterations, and to celebrate the building’s historical and social importance.” said Jen Langfield, who was named Regional Project Architect of the Year at the 2019 RIBA Yorkshire Awards for her work on the Hollis Building. Three long North-facing rooflights flood the space with daylight, enhancing the texture of the walls and offering new views of the sky.

The Wall-abutted Flushglaze is a flat fixed rooflight with no visible internal framework. Glazing Vision Secure and Secure+ roof lights are Building Regulations Approved and Document Q compliant, tested to LPS2081 Issue 1: 2015 certified by the Loss Prevention Certification Board and approved Secured by Design.

Each skylight is double glazed with a heatsoak tested low-emissivity outer pane, an 18mm silicone sealed argon spacer and a heat-strengthened PVB laminated inner pane. In addition to Jen Langfield’s individual award, The Hollis building itself achieved Regional Small Project of the Year at the 2019 RIBA Yorkshire Awards.
