Castle Quarter is a seven-storey, mixed-use development in the heart of Swansea City Centre awarded at RIBA Stage B and designed to achieve code for Sustainable Homes Level 3 for the residential elements. This design and build scheme was undertaken on a brownfield site situated in the centre of Swansea with a medieval castle and retail units alongside, and busy A roads to the front and rear.
The project includes 26 affordable apartments for rent and four duplex apartments for sale above the ground floor commercial units. Construction comprises a multi-storey, cast in-situ, reinforced concrete frame which rests on a split-level raft foundation with a concrete retaining wall across the site. The lower level, at 32m below street level, comprises seven-storeys of residential accommodation, while the upper level comprises four-storeys of accommodation and retail units.
The external cladding is a mix of predominantly face brickwork, zinc and copper cladding, and architectural stone, supported by the reinforced concrete frame and SFS metal framed wall. The steel framed roof structures are finished with a mixture of pitched slate, zinc standing seam roofing, and a bitumen insulated flat roof. Windows to the residential areas are Nordan timber/aluminium composite.
Dawnus designed the development around ‘off limits’ archaeological zones of the neighbouring Swansea Castle, and also designed and constructed the project to stringent acoustic levels. This included commissioning acoustic tests at the BRE Headquarters in London for a bespoke Siniat wall.
In 2015 the project was awarded a Bronze Considerate Constructors Scheme Award.
