THE former Terry's chocolate factory building in York re-named The Residence, luxury apartments by developers PJ Livesey who are converting the Grade II listed building off York's Bishopthorpe Road

SHEVTEC ventilation protects residents at former Terry’s chocolate factory

  • 11 Apr 2017

The former Terry’s chocolate factory in York has undergone a £38 million conversion, transforming it into a development of 173 luxury apartments. 

‘The Residence’ is a Grade II listed, art deco style former chocolate factory which comprises 1-3 bedroom apartments, together with penthouses, located over five storeys on a 27-acre (109,000 square meter) site.

The site was transformed in partnership with heritage developers and contractors, PJ Livesey, who specified SE Controls smoke ventilation systems to comply with building regulations and other key legislation, including BS7346 and BS9991. 

SE Controls’ SHEVTEC smoke control system was chosen to ensure escape routes can be kept clear of smoke in the event of a fire, so residents can evacuate safely. 

SHEVTEC automatic opening event (AOV) louvres have been fitted at the head of four individual smoke shaft systems, to allow smoke to escape when triggered by the smoke and fire system sensors. The building’s stairwells also use AOV windows to ensure smoke can be vented effectively from escape routes, and central staircases are vented using roof access doors fitted with automatic actuators.

The SHEVTEC system operates on a floor-by-floor basis. When smoke is detected within any of the protected corridors or lobbies, the system is triggered, automatically opening smoke doors and AOVs to allow smoke to be removed from the affected area. 

The system is controlled by a series of SE Controls OSLoop smoke vent zone controllers together with OSLoop Co-ordinators and alarm monitoring modules, dedicated to each smoke shaft.

Every floor of the building features tamper proof manual control points (MCPs) that allow the system to remain active until fire service personnel rest the activated floor via the MCP. In the event of a power failure, a full back up battery system ensures that the system remains operational.

Terry’s site: future developments

Further redevelopments planned on the former Terry’s site include the conversion of the landmark ‘Terry’s of York’ clock tower and adjacent building into 22 apartments. 

The main HQ building is to be converted into a care village by Springfield Health, while around half of the 27 acre original site has been acquired by David Wilson Homes for a new residential development.
