Knightstone House in Weston-Super-Mare is an 82 apartment sheltered housing scheme for the over 55's which was constructed in 1979. The services installations were more than 30 years old, at the end of life, and required replacement throughout. We were responsible for the design, specification and site management of the refurbishment of the building common areas, and modifications to the apartments.
For the Landlords areas this involved the replacement of the existing electrical and mechanical services installations back to the intakes. Existing stack extract fans were replaced with new inverter controlled models with fan speed controlled from system pressure to provide energy savings.
The building is of modular concrete construction with insitu wiring and limited floor / soffit heights. We trialled and developed a system using shallow cable baskets to minimise the ceiling void required for the new wiring which in some areas were only 2.1m AFL.
Lighting which had been on 24/7 control was replaced and switched via microwave detectors to provide energy and maintenance savings.
The wiring systems throughout are buried within the concrete. To avoid the costs and difficulty of rewiring the apartments, we changed the Distribution Boards to incorporate RCD protection and permit the reuse of the existing cabling.
As a part of the works we replaced the boilers, radiators and control system to modern energy efficient models. The works were completed with the tenants in occupation using temporary boilers to retain the hot water service to the apartments.
