Background

One Nine Elms

One Nine Elms occupies a prominent location on London’s South Bank and the site is part of the Nine Elms Regeneration Scheme which will consist of several large scale and prominent new developments. At the eastern most corner of Wandsworth, the One Nine Elms site will be the entrance for ambitious proposals to create a new public realm extending from the Vauxhall transport stations through to the redevelopment of Battersea Power Station.

Dalian Wanda Group, one of China’s leading commerical development companies, purchased the site in November 2013 and plan to deliver 494 residential apartments, a public viewing and observation deck and the first Wanda Group 5* Vista luxury branded hotel in Europe.

The existing buildings at the site have now been fully demolished and works for the sub-structure are underway. The Main Contractor is due to be appointed and construction activities will significantly increase over the coming period.

Solution

Servicing Strategy

Providing high-density mixed use accommodation on a city site meant that available space was at a premium. Sweco developed servicing strategies that minimised engineering plant space taken by rationalising and consolidating systems.  A central energy centre solution was conceived by Sweco to fulfil the energy efficiency targets to achieve planning consent and to maximse basement areas in which to accommodate our clients requirements.

A key focus for the design team was on optimising the tower cores by developing an efficient vertical transportation strategy and minimising the distribution of services throughout the towers thereby reducing the service riser requirements. The benefits of these solutions included optimal space planning, reduced energy use, capital cost savings and increased nett saleable areas for the client.

Façade Performance

The building façade is an integral part of the building design and engineering services solutions.  The building façade has been engineered to provide optimum daylight penetration while minimising the solar gain and heat losses. A high performance triple glazed façade has been specified throughout the towers and allows the architectural aspirations to be realised, whilst operating as a fully functional climate modifier specific to the site and orientation.
