Halkin Enters the Knowledge Quarter at Mainframe, Euston

We’re excited to announce that Halkin has signed a major lease at Mainframe, Euston, taking 30,000 sq ft across three floors of this landmark building in London’s Knowledge Quarter. The new site, set to open in April 2025, will be our ninth location and our first in this rapidly growing innovation district.

Located on a prominent island site adjacent to Euston station, Mainframe has been comprehensively refurbished with a strong focus on sustainability, wellness, and technology. It now boasts WELL Platinum, EPC A, BREEAM Excellent, and WiredScore Platinum certifications, alongside amenities including a commuter zone and a communal rooftop garden.

Our new Euston site will feature beautifully designed private offices, meeting rooms, and podcast facilities, with cutting-edge technology and standout interiors across the ground, first, and second floors. As ever, our goal is to create spaces that help companies attract and retain top talent—spaces that feel as good as they look.

This expansion brings Halkin’s portfolio to over 345,000 sq ft of workspace, offering more than 5,000 desks across London. As a growing family business, we’re proud to forecast revenues in excess of £30 million in 2025, and this opening marks a significant step in our journey.

Mainframe is now two-thirds let, with a strong mix of occupiers including Snyk, Zinc VC, Xcede, and lifestyle brands 1Rebel, Gail’s, and Pizza Pilgrims.

We look forward to welcoming clients to this exceptional new location and to building a strong partnership with Arax Properties and Eurazeo, whose vision for Mainframe aligns closely with ours.

Jonathan Kingshott, CEO of Halkin, said:

“As our portfolio continues to expand, we’re particularly excited about bringing our design-led serviced offices to London’s Knowledge Quarter. This is a space built for innovation, and we’re proud to be part of its future.”
