Work on a new headquarters for HSBC in Birmingham is expected to start imminently after a lead contractor was appointed.
It will house thousands of staff working in HSBC's business and retail banking arms which are relocating from Canary Wharf in London as part of government plans to separate off investment work from other sections of high street banks from 2019.
2 Arena Central, which will be opposite the Library of Birmingham and next to Alpha Tower, will have grade A office accommodation and ground floor retail or restaurant space across 210,000 sq ft.
It was acquired by HSBC earlier this year.
Work is due to start on the £66 million contract in September once demolition and clearance has been completed on the 9.2-acre site which used to house the old ATV studios.
Galliford Try, which also built the £32 million extension at Edgbaston Stadium, will also deliver more than £10 million of public realm which has been designed by landscape architectural practice Gillespies and will comprise more than 50 per cent soft landscaping to create an urban meadow.
The works will also include the creation of Bank Court, a new public courtyard behind the Municipal Bank building in Broad Street and extensive new landscaping around Alpha Tower.
The wider, one million sq ft Arena Central project will eventually have five new buildings - two residential and three commercial - and a new Holiday Inn Express hotel on land next the Alpha Tower and the Crowne Plaza hotel.
It will also be connected to New Street station and the wider city via an extension to the Midland Metro tram network with a dedicated stop outside.
A joint venture between Miller Developments and Pro Vinci Asset Management, called Arena Central Developments, is behind the project.
Jonathan Wallis, from Arena Central Developments, said: "This site represents a landmark development for Birmingham, with the forward purchase of 2 Arena Central marking one of the most significant inward investment deals to take place in the region for over a decade.
"Galliford Try emerged from a highly competitive tendering process as the stand out contractor that we have entrusted to deliver our vision at Arena Central.
"We are focused on the start of the construction phase of this project, following the completion of the demolition works."
2 Arena Central was designed by Ken Shuttleworth of London-based Make Architects, the practice behind The Cube and The Gherkin in London, and will have the capacity to accommodate up to 2,500 people.
It is claimed to be the first building in Birmingham to be constructed to LEED (Leadership in Environmental and Energy Design) gold accreditation.
Simon Burton, managing director of Galliford Try West Midlands and South West, said: "This is a significant appointment, with Arena Central representing one of the most high-profile active development sites in Birmingham.
"We will now work closely with Arena Central Developments to ensure the delivery of a high-quality product that matches the aspirations of this statement site."
EC Harris acted as quantity surveyor and employers' agent for Arena Central Developments.
