Strata SE1, London – propelling sustainable regeneration

Abstract

Strata SE1 is a new 43-storey, 148 m tall reinforced concrete residential tower leading the sustainable regeneration of the Elephant and Castle area in London, UK. With a curved triangular footprint and three 9 m diameter wind turbines, the tower has been designed economically and built quickly on a confined city centre site. This paper describes the design and construction of the project, which used a system of ‘walking columns’ to achieve its tapered shape, with slabs acting as struts and ties. Headed reinforcement bars were used within the ties – one of the first applications in a UK building.
