Camerons currently occupies the 1st, 2nd and 3rd floors of the building in the City, with the lease agreement meaning the firms will take up additional levels on the 6th and 7th floors.
The proposals for the move-in were first reported last month shortly after the three firms voted to merge in early October. At the time, Olswang chief executive Paul Stevens said the three firms were still working out the ‘day-to-day mechanics‘ of the union in relation to property arrangements.
Camerons moved into Cannon Place in June 2015, cutting its total floor space in London from 190,000 sq ft to 140,000 sq ft. The deal for Cannon Place allowed Camerons to benefit from a lucrative property agreement which won them a six-year rent-free deal on the office space.
Olswang will move out of its offices at 90 High Holborn, while Nabarro will move from its offices at 125 London Wall, new offices the firm only occupied in 2014.
The merger between the three firms was confirmed on 11 October when the three partnerships voted to combine, taking on the CMS branding. The firm will have combined revenues of up to £450m when the combination goes through in May 2017, as well as around £1bn in revenue in the combined CMS network of European firms.
Nabarro managing partner Andrew Inkester said: ‘This is an important step in delivering a successful merger. Our people in London will be under one roof as one team in May. The technology and collaborative work space at Cannon Place will help the new firm make the most of its combined talent.’
