The 183,000 sq ft office building (pictured above) will complete the first phase of the Paradise development.
The two buildings combined will offer more than 350,000 sq ft of office and retail space and are expected to be completed in late 2019.
BAM Construction – which was awarded the contract in 2017 – will manage over 200 workers on the scheme, who will construct the building and erect two new tower cranes in April to assist with the work.
The two basement levels have already been constructed as part of the site enabling works.
The structural and architectural design of the project will be delivered by BAM Design.
The completed Paradise scheme will deliver up to 10 new flagship buildings offering offices, shops, bars, cafés, restaurants and a four-star hotel across 17 acres in the heart of Birmingham.
“The start of work on Two Chamberlain Square, our second speculative office building, underlines the momentum gathering around Paradise and marks yet another milestone for the city’s most vibrant, mixed-use development,” said Rob Groves, regional director of Argent, development managers for Paradise.
“Two Chamberlain Square will be an exceptional building, leading the way in modern workplace design and performance.

“As it takes its place on the city’s ever changing skyline over the next year, it will deliver a prestigious commercial address at the civic heart of Birmingham.”
Rod Stiles, regional director at BAM Construction in the Midlands, added: “BAM is already working closely with the Paradise team to deliver this prestigious, landmark building.
“We’re bringing ultra-modern construction techniques to this complex site in the civic heart of the city, surrounded by some of the country’s most beautiful Victorian buildings.
“Argent and BAM started our industry-leading partnership in 1994 with the first new building at Brindleyplace and we have now delivered over 30 award-winning buildings together.
“We expect this productive partnership to make Two Chamberlain Square equally successful.”
