This six storey building is of concrete framed construction utilising a flat slab design for the floor plates. Transfer systems are included at first floor to provide for an open environment in the public spaces at ground floor.

The foundation design utilises CFA piling and extensive sheet piling to facilitate basement construction on the restricted site.

The project also included surface water attenuation design in line with the requirements of Dwr Cymru Welsh Water.


  • RIBA Design Excellence Award in 2010.
  • Basement construction adjacent to main railway line embankment meant that vibration had to be limited.
  • Smooth CFA piling was used to provide virtually vibration free piled foundations.
  • Complex 'transfer' structure at first floor allows hotel bedroom layout above, but light and airy spaces at ground floor for lobby and car parking.
