Astrea has selected Mace to build a new office development in Berkeley Square, London.

Located in the heart of Mayfair, 38 Berkeley Square will provide 85,000 sq ft of premium office space across nine stories with over 7,000 sq ft of communal terracing. The scheme includes 9,000 sq ft of retail use on the ground and lower floors.

Mace will collaborate with the Astrea team to deliver innovative low carbon solutions, working towards the highest sustainability standards of BREEAM Outstanding, WELL Platinum and LEED Gold. The building will also achieve WiredScore Platinum.


Designed by architects Piercy & Company, the transformation of 38 Berkeley Square will complement the character of the surrounding properties by using a mix of precast facades and Portland stone.

Completion is expected in the first quarter of 2024.

Ged Simmonds, Managing Director for Commercial Offices and Residential at Mace, said: "We are delighted to work on the transformation of 38 Berkeley Square, on behalf of Astrea. Our team will support the client’s vision for a destination office space with an innovative sustainability strategy, minimising carbon emissions during demolition and build. Drawing on our experience in creating commercial office buildings in the City and heritage developments, we will deliver a new landmark in the heart of Mayfair."

Rob Rotbart, Construction & Cost Director at Astrea, said: "Astrea is excited to be delivering our first major development with Mace at 38 Berkeley Square. Both teams are aligned in driving innovation through construction to deliver a truly long term Net Zero Carbon workplace of the highest calibre."
