Office building Moor Place case study

Steel was chosen for the framing material because the construction time was shorter than if the frame was made of reinforced concrete.

Moor Place, formerly known as Moorgate Exchange, is an iconic 12 storey office building located in the Square Mile of the City of London, which was completed in 2014. It is a landmark structure with two storey-high V-shaped columns and an angled façade which forms a roof line with stepped landscaped terraces over six levels (Figure 1). The distinct wedge-shaped form was the result of site constraints: the ‘rights to light’ of local residents, the height limitations of the St Paul’s viewing corridor and the partial overlap of the site’s footprint with the Crossrail tunnel. The use of structural steel enabled the net lettable space to be maximised by the use of long clear spans, fire protection on the columns was minimised by infilling with concrete and a reduced overall floor depth allowed the incorporation of an additional storey. The total steel tonnage was 2,900 tonnes. The building achieved a BREEAM “Excellent” and a LEED “Platinum” sustainability rating for its low impact on the environment through the use of high performance facades, high efficiency HVAC systems and other conservation measures. It is one of very few buildings in London to achieve these highest environmental standards. The cost of the building was £56 Million.
