The new structure within the existing building consists of infill sections located in the otriums to increase the floor space.

Steel beams were designed to span between the concrete frame with resin anchor fixings, carrying a composite slab to support the raised access floor.

Smaller voids were infilled with composite slabs spanning between perimeter angles fixed to the concrete frame. At roof level, a new steel framed structure was added to provide an additional floor which was limited by the number of allowable column positions. Cellular beams were employed to span the large distances using composite action with the metal deck slab.

Along Colmore Row and Barwick Street, the face of the building at fifth and sixth floors was extended outward from the existing building line.

The Grade II listed, 19th century Banking Hall has been transformed into a new reception area whilst to the rear of the building the elevation has been removed and replaced with a full height glazed façade.

The design of the building was centred around achieving very low energy running costs for Grade A office accommodation whilst providing open plan flexible accommodation. To achieve this a chilled beam air conditioning system was utilised which required high thermal mass and no downstand beams beneath floor plates.

CWA adopted a Slimfloor beam and precast floor solution which satisfied stringent M&E requirements whilst also allowing fastrack construction techniques and processes.

The first phase of 200,000sq ft of commercial development in solihull, Project Fore is a blue chip commercial development.

The site was cut and filled to form the building platforms, using lime stabilisation techniques. Both buildings were constructed on driven precast piles, founded at approximately 13m in depth.

Reed beds and balancing ponds were created within the site boundary and adjacent the river Blythe, which is designated a site of special scientific interest.
