Hertshten Properties has appointed Mace as the construction partner for a new 32-storey mixed-use tower at 85 Gracechurch Street in London, UK. Located in the Leadenhall Conservation Area adjacent to the Grade II-listed Leadenhall Market, the project features a Woods Bagot architectural design. It will replace a 1930s office building with approximately 235,000 square feet of modern office space, cyclist facilities, and a terrace with expansive views.

Completion is expected in 2030.

The development aims to be one of London’s most sustainable skyscrapers, operating as an all-electric building that meets or exceeds environmental standards set by the Greater London Authority and the city. The project targets a Building Research Establishment Environmental Assessment Method (BREEAM) Outstanding rating upon completion. It incorporates energy-efficient mechanical systems, extensive greening measures, natural ventilation, and an automated cycle hub with 444 bicycle parking spaces.

“We are delighted to announce the appointment of Mace as the main contractor for 85 Gracechurch Street,” said Ron Hertshten, CEO of Hertshten Properties UK. “85 Gracechurch will be a state-of-the-art office building, delivering approximately 235,000ft² of premium office space alongside a host of extraordinary amenities. Designed to achieve market-leading environmental performance, the development will set a new benchmark for sustainable office space in the City of London.”

The project also reflects the site’s archaeological significance, which has influenced its design, according to Mace. Additionally, it includes restoring a walkway connecting Gracechurch Street to Lime Street Passage, enhancing local connectivity and supporting Leadenhall Market’s transformation into a vibrant, seven-day-a-week hub.

Mace has begun pre-construction services following a competitive bidding process, with the project expected to be completed in 2030. The development is set to contribute to London’s sustainable urban growth by offering high-quality office space and amenities while prioritizing environmental responsibility.

The partnership underscores Mace’s growing role in sustainable construction projects. Earlier this month, Mace collaborated with Arup as a programme management partner for a development in Hong Kong, further demonstrating its expertise in large-scale, innovative projects. The 85 Gracechurch Street tower is poised to enhance London’s skyline, delivering economic and environmental benefits through advanced design and construction practices.
