Sainsbury’s has signed for 68,002 sq ft at Helical and Ashby Capital’s The JJ Mack Building in London.
It is anticipated the retailer will move its existing London office from 33 Holborn Street to nearby 33 Charterhouse Street in the next two years.
Sainsbury’s has taken the first, second and third floors of the 200,611 sq ft building, with the sixth and seventh floors – totalling 37,880 sq ft – let to Partners Group and the 13,408 sq ft ninth floor, let to Corio Generation. The JJ Mack Building is now 58% occupied.
The building is rated EPC A and it is anticipated it will receive a BREEAM Outstanding and NABERS 5* rating.
Simon Roberts, chief executive of J Sainsbury, said: “We’re delighted to have signed a new agreement that will see Sainsbury’s London store support centre relocate to 33 Charterhouse Street in 2025. This is a really exciting opportunity for us to create a modern and sustainable workspace that is better suited to our needs and ways of working as our business continues to evolve.
“Sainsbury’s has a long and proud history in London, dating back to 1869 when John James and Mary Ann Sainsbury opened their first shop in Drury Lane. We know that our success depends on our brilliant colleagues and by moving to a more flexible, efficient workspace we can remain committed to maintaining a presence in central London while taking another important step in delivering our Save to Invest plan, which will enable us to invest where it matters most to our customers.”
Gerald Kaye, chief executive of Helical, added: “Following the recent lettings to Corio Generation and Partners Group, we are excited to welcome J Sainsbury to The JJ Mack Building, which means we have now leased 58% of the 200,611 sq ft building. These lettings are clear examples of the bifurcation taking place in the market between the best in class office space and the rest.”
Peter Ferrari, chief executive of AshbyCapital, said: “The success of The JJ Mack Building in attracting market-leading rents from forward-thinking occupiers is testament to its high-quality design, strong sustainability credentials, extensive amenities and excellent location, and we are confident that our new occupiers will benefit from their inspiring new workplace.”
