At 174m high, St George’s Wharf Tower is one of the tallest residential buildings in the United Kingdom. The tower contains 167 one, two and three-bedroom apartments. The 48 residential floors are crowned by a mechanical penthouse and an 11.4m-high wind turbine.

Energy efficiency is one of the building’s most important features, with the turbine powering the tower’s lighting. Water is drawn from the London aquifer at the base of the tower, where the use of heat pump technology extracts warmth from the water and uses it for heating residences in the winter. The St George Tower requires a third of the amount of energy used by comparable structures under wind loading.

Key technical challenges

  • The primary tower structure consists of a composite slab and beam structure. Due to the long beam spans and thin slab, extensive analysis for footfall vibration was required to ensure the structure achieved code requirements and client expectations.
  • Working with the existing structure and developing design solutions that strengthened rather than demolished.
  • Extensive co-ordination with the mechanical engineer to develop a strategy that minimised beam penetrations and beam notches.
  • Differential shortening analysis with consideration of mega truss, steel structure, concrete structure and existing structural elements

Environmental performance

  • 5 Star Greenstar
  • 5 Star NABERs Energy and 4 Star NABERs Water ratings.

Our Approach

Our approach to this job during the initial due diligence and VE phase resulted in reduction of the core wall and typical slab thicknesses. We also conducted an in-depth study of the dynamic performance of the building and its piled foundation under different load conditions to satisfy both strength and occupant comfort criteria.
