Carillion is already the contractor for phase one enabling and infrastructure works on the £450m development project and has now been named as the contractor for the seven-storey building situated at the centre of the development – One Chamberlain Square.

Designed by architect Eric Parry, the 172,000 sq ft building will include a roof terrace on the sixth floor and restaurants and retail units at ground level

Carillion operations director Simon Dingle said: ‘Paradise is a crucial project for the city and Carillion is very proud to be playing such a major role in its delivery. We are looking forward to completing the enabling works on the site and being able to bring our considerable experience to construct One Chamberlain Square.’

The redevelopment of Paradise Circus is being undertaken through a joint venture company established in September 2013 between Birmingham City Council and British Telecom Pension Scheme (BTPS), managed by Hermes Real Estate Investment Management Ltd (HREIML). Argent is the development manager for the joint venture.

Argent regional director Rob Groves said: ‘Carillion has been making good progress preparing this complex site and the surrounding infrastructure and is about to start delivering the foundations and basement for the first phase of building. We are very pleased that Carillion will now be able to continue this work and bring One Chamberlain Square to life.’

The new Paradise Circus will eventually have eight new office buildings and a hotel.
