Helical, the property investment and development company, and its partner AshbyCapital, the property investment advisory company, have launched One Bartholomew, their new 12-storey office building in London’s Farringdon, close to the new Elizabeth Line station.

One Bartholomew is the latest completed element of Barts Square, a new mixed-use quarter in the heart of London. The 215,000 sq ft grade A office building offers 19,000 sq ft floorplates with high levels of natural light, 336 cycle storage spaces, luxury changing rooms with high-quality showers and drying rooms, and an expansive double-height reception featuring a unique neon lighting installation that spells out One Bartholomew in barcode. Designed by award-winning architects Sheppard Robson, the building has views of St Paul’s Cathedral to the south and looks out over the tranquil new square created as part of the wider Barts Square development, where new restaurants Lino and Stem + Glory have recently opened.

Gerald Kaye, Chief Executive of Helical, commented:
“With the completion of One Bartholomew, two new restaurants now open and homes continuing to see strong interest, it is exciting to see Barts Square coming to life. Located at the heart of London, where the City meets creative Clerkenwell, Farringdon has a unique character. It is steeped in history, with the iconic Smithfield market and the oldest standing church in London; it is on the culture mile, close to the Museum of London, Guildhall School of Music & Drama, Barbican Centre and planned new concert hall; and has a wealth of vibrant bars and restaurants for those living and working in the area to enjoy.” Peter Ferrari, Chief Executive of

AshbyCapital, added:
“Having previously invested in this area, we know how popular it is with a range of occupiers, and this is only set to intensify once Crossrail arrives. With great transport links from Farringdon, Barbican and St Paul’s stations already, and the kind of thoughtful, tenant-focused amenities that occupiers of our buildings have come to expect, One Bartholomew is an exceptional building in an increasingly sought-after location. The Trade Desk’s pre-let of three floors is testament to the building’s quality; there is strong interest in the remaining space and we look forward to announcing further tenants soon.”

David Taylor, partner at Sheppard Robson, said:
“Architecturally, the building stands as a simple but finely detailed form that marks the step change in size between the edge of the conservation area and the larger developments of the City behind. The building’s scale and iridescent facades mark the arrival of a major new development and public space that form a key part of the wider Barts Square project.”

The deal comes ahead of the building’s completion later this year. One Bartholomew will offer efficient and flexible floorplates, typically of 19,000 sq ft, within a Grade A office building designed by award-winning architect Sheppard Robson.

Peter Ferrari, Chief Executive at AshbyCapital, commented:
“This significant pre-letting to a global media tech company several months before completion is testament to the wide ranging demand for high-quality office space close to the new Elizabeth Line station at Farringdon. With a wide and growing range of amenities excellent transport links – and a creative vibe, this is London’s new neighbourhood in which we are creating a first-rate new office building.”

Gerald Kaye, Chief Executive of Helical, added:
“It is exciting to welcome the first office occupier to our Barts Square development as this new mixed-use destination takes shape. Combining homes, retail and office space with landscaped public areas, this is set to be a fantastic new place to live, work and spend time at the heart of one of London’s most vibrant locations.”
