The agency fought off competition from six agencies in a pitch shoot-out and will promote development company Ballymore's Embassy Gardens, which will include nearly 2,000 new homes and a large retail space.
The project is part of a wider regeneration plan for the area of London that stretches along the south side of the River Thames between Battersea Park and Lambeth Bridge.
The agency has been briefed to assist Ballymore in positioning and marketing the developments, in addition to maintaining relationships with key local stakeholders.
A spokesperson for The Communication Group said: ‘Embassy Gardens is set to be one of London’s most exciting residential developments and has a central role to play in the regeneration of the whole Nine Elms area on the South Bank.
'It will be at the heart of an entirely new waterside neighbourhood in central London and it is our role to position it as a premium destination London-wide and to international audiences.’
As well as housing, Ballymore’s plan will include a 130,000 ft² of retail space, landscaped gardens, a riverfront walk threading between Embassy Gardens and Battersea Park, a hotel and vibrant new bars and restaurants.
It is part of a wider effort to breathe new life into the area that should see the creation of 16,000 homes, with the US Embassy relocation from Mayfair at the heart of the drive.
Emma Johnson, The Communication Group’s head of the destination and chairman of the management board, is leading the account. She will report to Hayleigh O’Farrell, marketing manager at Ballymore.
