This special category recognised the sensitive adaptation of historic and heritage buildings through the introduction of daylight from above. It celebrated the first generation of projects using the new VELUX Heritage conservation roof window range to enhance traditional buildings while respecting their architectural character and cultural value.

Judges assessed entries based on the skill and care with which daylight had been introduced to support the ongoing use and enjoyment of heritage structures. Consideration was given to how natural light enhanced the reading of original features, the protection of significant fabric, and the thoughtful placement of roof windows in response to the building’s form and local context. Successful projects demonstrated how daylight could be used to revitalise historic spaces - improving their function, atmosphere, and long-term sustainability without compromising their integrity.

Lower Paradise Mill, a Grade II listed silk mill built in 1862, stood as one of the last surviving examples of Macclesfield’s industrial heritage — complete with working Jacquard looms and a distinctive attic designed to admit natural light while reducing fire risk. Over time, however, failing rooflights covered with yellowing sheeting had compromised both the building’s protection and the quality of light within, threatening its continued use as part of the Silk Museum.

With matched grant funding and under tight deadlines, owner Allmand-Smith undertook the mill’s most extensive restoration to date. Led by conservation architect Simon Revill of Cymes Conservation, the project replaced all rooflights, restored the cast iron valley gutter with a new aluminium lining, and carefully removed and reinstated the original Welsh slates laid in diminishing courses.

Twenty-six VELUX Heritage conservation roof windows were selected for their durability, discreet appearance, and compatibility with the historic fabric. Their slim construction height allowed them to sit flush with the slate roof, preserving the mill’s original profile while flooding the attic once again with natural light. Internally, the timber finish and floating structural carpentry respected the original purlins. The windows’ familiar detailing and quick installation (just one hour per unit) made them a practical yet sensitive choice.
