The £350m London Wall Place scheme submitted as a detailed application to the City of London was formerly known as the St Alphage site, but has been redesigned by architects MAKE.
The largest of the two buildings, 121 London Wall, is designed as a 300,000 sq ft headquarter office building adjacent to Moorhouse its smaller sister at 123 London Wall will provide 195,000 sq ft of office space in a 16-storey tower.
The application is due to be decided by summer 2011.
Hammerson is seeking a prelet for 121 London Wall. Subject to planning consent, completion is due in 2014 for fit-out, ready for occupation in mid-2015.
Over half of the site is dedicated to open space creating a new destination for the area through a series of new gardens set amongst the historic monuments including the City Wall and St Alphage Church Tower remains.
Martin Jepson, Hammerson managing director, London Group, said: “This is an extremely complex site in a prime City location.
“MAKE has delivered an outstanding scheme that respects its surroundings and will change the perception of a traditional City office building.
Ian Lomas, MAKE, said: “The team has developed a bespoke building that is designed to adapt and evolve to changing tenant needs and environmental challenges. Externally the materials, form and gardens deliberately create a unique sense of place in this pivotal City location.”
