Practical Completion has been achieved for the Head Office of Castles and Coasts Housing Association. Housed in a Grade II Listed Building, the project succesfully balanced the preservation of historic character and the sustainability aspirations of the client. PV panels, secondary glazing and retrofit insulation of external walls has considerably reduced the carbon footprint. The building is now a comfortable and contemporary office with spaces geared to flexible working and a range of bookable offices and co-working open plan office spaces.
