Ulster Bank, Belfast
Project Description
The 125,000 sq ft seven storey headquarter building is built on top of a two storey basement providing 120 parking spaces. The development was created around the façade of an old Methodist church designed by Dublin architect, Isaac Farrell. One of the requirements on the project was that the original church portico had to be retained and incorporated into the design of the new structure.
Site Details
The new building is 7-storeys and consists of a reinforced concrete frame with flat slab floor construction including a double storey basement. The basement construction involved 230m of secant-piled wall with temporary pre-stressed cross-propping to restrict horizontal movement. Due to the depth of the excavation, the building is supported on natural underlying subsoils. The flat slab floor construction was adopted to stay within building requirements, maximising the number of storeys.
