This development, known as Granary Wharf, is the result of regeneration around the historic Leeds & Liverpool Canal, minutes from Leeds city centre. We provided civil and structural engineering for two landmark residential buildings — Candle House and Watermans Place — and a footbridge linking the wharf to the central area of the city.
Access to site was one of the challenges for this design and build project — a hotel was also under construction between the two apartment blocks. The cranes on site required approval for use close to nearby power lines and a substation needed to be accommodated within the design. Both buildings have CFA pile foundations.
The cylindrical Candle House provides 160 apartments over 22 floors. The structure twists by 2.75° every fourth level. Its concrete frame and floor slabs support the brick façades, with lifts and stairways in a concrete core. Copper balconies sit within the footprint of the structure. The communal roof terrace is timber decked and enclosed with glazed panels in the concrete frame.
The similarly-structured Watermans Place has a terraced design, providing 122 apartments over 14 floors at its highest level, and a small number of retail units at ground level. The prefabricated balconies were clipped into position after scaffolding removal to ensure the quality of finish. Communal roof terraces are clad in copper and western red cedar.
The cable-stayed footbridge spans 34m across the River Aire, supported by a single Corten steel cantilever portal frame. Its deck consists of steel plate over a steel frame. Within the depth of the deck, nine 160mm diameter pipes carry all services to the apartments and hotel.
