The Lexicon


Project Description

  • Client: Skidmore Owings & Merrill
  • Main Contractor: Mount Anvil
  • Engineer: WSP

Part of the City Road Basin Masterplan, The Lexicon is 36 storeys high, making it Islington’s tallest building. Designed by world-renowned Skidmore Owings & Merrill (SOM), it was planned to add another high point to the constantly developing and dynamic London sky.

Completed in summer 2014, this project commenced September 2012 and aimed to be the impetus for new growth in the area.

Moments from Angel tube station and Silicon Roundabout, this incredible scheme comprises 307 apartments; 200 for private sale and 107 affordable housing units which will be managed by Affinity Sutton. The development also includes 785m² of mixed-use commercial space, 52 car parking spaces, and private residents’ spa and lounge. The 200 City Basin waterside apartments also feature unrivalled views and 24hr concierge.

The gross development value of this project was £160m, and Morrisroe undertook a large part of it, from the slipform lift and stair core of Block B of the 36 storey tower, to the basement car park. There were some very challenging aspects to this project, including a new, single level, waterproof basement, the swimming pool and spa facility, also in the basement, and working with limited space and high environmental requirements.

Other parts of the project which were undertaken by Morrisroe were the piling subcontract for bearing and perimeter piles, unexploded ordnance surveying, groundwater heat system works, working with the historic foundry with massive concrete obstructions below existing basement, and the demolition of that existing basement space.
