JS Wright has been awarded a contract for around £750,000 with Solihull-based Barteak Developments.
The company will include a variety of installations at the £9.7million development at Stanbridge Hall in Ruskin Road for social enterprise Housing 21.
J S Wright will be designing and installing low-pressure hot water heating, as well as low surface temperature radiators, heat recovery ventilation, and domestic water, soil and waste, sanitary ware and gas services.
Work will start on site this month, which is being built on the former Stanbridge Hall site of Banbury School. The building will retain its iconic 1930s facade.
Stanbridge Hall will provide 70 self-contained rented and shared ownership apartments for the over 55s.
It will also have a shop, restaurant and a hair & beauty salon as well as a £500,000 day centre funded by Oxfordshire County Council when completed in February 2012.
