Project Description

  • Client: Berkeley Homes
  • Architect: Michael Squire – Squire & Partners
  • Engineer: Meinhardt

Situated at of one the most iconic locations in London, One Tower Bridge provides a mixed use development, comprising of nine blocks, with a total 396 residential units, commercial, cultural spaces and a single storey basement area. The location profile could not be higher, with individual apartments selling for prices between 1.3m to 8m.

Blocks 1 to 8 consist of 353 residential units and ancillary floor space, including an estate management facility, a large cultural space, and commercial units accommodated in buildings of up to eleven storeys. The development also includes a 20 storey residential tower block with a roof area and a lantern-like structure at its top. Finally, the scheme also provides communal and private amenity spaces, including an extension and improvement to Potters Field Park, along with associated highway works and landscaping.

Acting as the principal contractor, Morrisroe commenced work in October 2011, with a package which incorporated extensive sub and superstructure works. The groundworks part of this project included demolition of the previous reinforced concrete basement and pile walls, a 70,000m³ bulk excavation and remediation exercise, as well as new foundations and piling.

The single-level waterproof reinforced concrete substructure also provides an underground swimming and leisure suite, a basement car park and a 65,000 sq. ft. cultural space. Particular challenges during this phase of the project included the logistics arrangements to allow for the safe arrival and erection of the site cranes, and the management of over 100 HGV truck movements via Potters Field and Tooley Street, all of which occurred during the 2012 Olympic Games and the Golden Jubilee celebrations.

The reinforced concrete superstructure works were completed in April 2014, and consisted of nine residential blocks, reaching up to 20 storeys. The blocks were built concurrently, in order to meet the overall program requirements, and were delivered two months ahead of schedule.

The superstructure posed a number of technical and logistical challenges; in particular the first floor slab to the river facing Cambridge House, which incorporates substantial 2m deep drop beams, to allow for large column spacing. This helps to maintain the wide-open commercial and retail space on the ground floor level. Other challenges included the unprecedented and elaborate offset and compensation applied to the Tower, which will control settlement and shortening as the building settles into its final position.
