A £35 million renovation and redevelopment at the seat of local government The Council House, Derby in the centre of the city, saw the transformation of the 50 year old building into an impressive, modern and energy-efficient headquarters.

Utilising Reynaers aluminium systems throughout for the windows and curtain walling the development, designed by architects Corstorphine and Wright, also incorporates a hydro electric scheme linked to the adjacent River Derwent that supplies the electricity used throughout the building.

To further enhance the insulation levels Reynaers CS 24-SL windows are used throughout. A three-chamber, thermally insulated system ideal for new build and renovation alike, they offer slim exterior contours and glazing beads making them a popular choice for renovation projects. Incorporating enhanced insulation levels they help improve the energy rating of a building, while blending in with the original style. Slim design makes the system extremely suitable for matching Georgian window design so often used for local government offices.

Assisting the modern appearance of the building and the impressive entrance to the public facilities Reynaers CW 50 curtain wall delivers a clean façade complementing the imposing features of the building. The system fits seamlessly in to the council house’s refurbishment and the carefully integrated extension helping to merge the two.

A spacious atrium facilitates significant natural light ingress into the interior via the curtain walling as well as providing a link to the various areas. These include additional office accommodation, a one-stop customer service centre, council chamber and members’ accommodation.

The renovation and re-development has increased the capacity of the original building from 500 to 1,900 employees and has allowed the council to centralise a number of its services closing older, less energy efficient premises in the process.

Main Contractors on the project were BAM Construction with fabrication and installation of the windows and curtain walling by AWS Turner Fain.

In addition to achieving the BREEAM ‘Excellent’ rating The Council House received an Energy Performance Certificate ‘A’ Rating.
