Quantal and City Glass Bristol deliver on a Grade II heritage project
City Glass Bristol has worked in close partnership with Quantal to deliver a complex aluminium roof installation, linking a Grade II Regency property to a new flat roof, brickwork extension.
The Grade II Regency building, located in the heart of Bristol, was extended by its owners to incorporate a new kitchen extension. However the extension was subject to strict planning controls. This included the condition that the new building was built a minimum of one metre away from the original building. As a result, City Glass Bristol was commissioned to install an aluminium Quantal atrium to seal and close the distance between the two buildings.
However, the fabrication and installation process was also subject to a number of planning conditions. For example, the profile was not only specified in a unique shade of cream but it had to be fabricated to 'fit' around original Victorian square downpipes. Not only that, just one connection between the roofing system and the original building was allowed while the use of lead flashing and cutting into the original brickwork was strictly prohibited.
Kevin Cole, managing director, City Glass Bristol said: "We had to adhere to a list of conditions laid down by the planners. By working closely with Quantal and incorporating the bespoke roof with our customised installation methods, we created a complex yet effective design that met all of the planning authorities' requirements."
The system included a number of innovative measures. By creating a special sealing detail, located between the rafter system and the wall, the single connection point was achieved. In addition, a special injection system was devised, similar to damp proof coursing, giving the construction the same level of weather tightness.
Furthermore, the profile was customised to fit around the Victorian downpipes and other intricacies of the building, while the colour was matched exactly using Quantal's in-house paint mixing plant.
Ian Cocken, national sales manager, Quantal, said: "Traditionally timber, and to a certain extent slim steel sections, have been dominant in the refurbishment of heritage properties. But the key to this installation was customisation and even though the Quantal system was aluminium, it formed an integral part of the only plan accepted by the planners.
"Bespoke Quantal systems can give fabricators and installers the flexibility and versatility to take on more intricate projects such as this. Not only does this mean increased access to different, and in some cases niche, markets but importantly to higher value, more profitable opportunities."
