Clementhorpe Maltings, York

VELFAC composite glazing, together with VELUX roof windows, have helped transform Clementhorpe Maltings, a Grade II listed industrial building, into an award-winning residential development of six stylish townhouses.

Clementhorpe Maltings was a challenging project says Ian Collins, Design Director at Mesh Architects which oversaw the build: ‘Our brief was to convert a run-down 19th century malt house into six stylish townhouses. As the building was Grade II listed we had to maintain the original architecture where possible, but also needed to insert new windows into the walls and roof. This allowed us to use modern building products, and so we specified the VELFAC system for the facades, and centre-pivot VELUX conservation roof windows wherever we could, to bring more light in from above.’ 

Working with Conservation officers, Historic England and the Association for Industrial Archaeology, Ian has deliberately installed the VELFAC and VELUX units alongside original architectural features to emphasise the combination of old and new. The clean, sharp, contemporary VELFAC frame design stands out against the old brick facades, and is in direct contrast with the traditional units specified for the original window openings. As conservation regulations limited window size, the slim VELFAC frame also brings valuable additional light into rooms and shared spaces, further enhanced by the generous use VELUX conservation roof windows sitting in recessed installations, deeper into the roof, and featuring glazing bars.

Both VELFAC and VELUX units also met the demands of Ian’s client, property developer Northminster, which wanted low energy, low maintenance glazing to improve performance across the building fabric. Northminster also welcomed the option to use a different finish on each element of the composite frames, says Ian: ‘The inner timber frames are painted white on both the VELFAC and VELUX units, giving the neutral finish that proves so popular with residents, and which brings more light into the interior. The aluminium external frames are all finished in grey - on the facades, this further emphasises the contrast between the modern VELFAC frame and the old brick, while allowing the VELUX roof windows to blend seamlessly with the grey slate roof. As a result, both VELFAC and VELUX units reference the building’s industrial history while also delivering contemporary style.’

Clementhorpe Maltings has proved to be a highly successful development, and won both the Conservation and Residential categories in the RICS 2017 Regional Awards, with the judging panel describing the project as ‘pioneering and outstanding’. The project went on to win the Residential category at the RICS Awards Grand Final, and also the 2017 Association for Industrial Archaeology ‘Creative Re-Use’ Award.
