The London commercial property market has spent the past 18 months in flux. Prime office space in the City has seen vacancy rates hover around 14 per cent—the highest in a decade—whilst rents in traditional business districts have softened by as much as 8 per cent year-on-year. Yet in Clerkenwell, a quietly ambitious developer is thriving by listening to what occupiers genuinely need.
Marcus Leigh's venture, established just three years ago, has quietly acquired three converted warehouse buildings along Exmouth Market and St John Street, converting 120,000 square feet into modular workspace environments. His approach departs sharply from the glass-and-steel towers that continue to struggle with lettings across the Square Mile and Canary Wharf.
Rather than offering sprawling open-plan floors locked into lengthy leases, Leigh's developments prioritise flexibility. Units range from 500 square feet for boutique agencies to 8,000 square feet for scale-ups, with lease terms from one to five years. Each property incorporates shared amenities—kitchens, meeting pods, outdoor terraces—designed to reduce the isolation many firms reported post-pandemic.
The commercial property sector has watched this model carefully. Knight Frank's latest London office report acknowledges that occupiers increasingly reject the 10,000 sq ft minimum leases common in the 1990s and 2000s. Instead, hybrid-ready, human-scaled environments command premium rents. Leigh's buildings, priced at £45–£55 per square foot annually, are letting faster than comparable City locations at £35–£40.
"People are tired of monuments," Leigh has noted in recent industry forums, according to property circles. The bet appears vindicated: his Exmouth Market flagship achieved 87 per cent occupancy within 14 months of completion, against a wider London average of 72 per cent for new commercial stock.
The success reflects a broader London shift. Tech firms, creative agencies, and professional services increasingly cluster in neighborhoods with character—Shoreditch, King's Cross, Clerkenwell—where workspace blends with cafes, galleries, and residential life. This diffusion away from traditional financial districts has reshuffled property values dramatically across the capital.
As the summer letting season accelerates, Leigh's team has already launched pre-lettings for a fourth property near Old Street roundabout. If the trend holds, the era of the monolithic London office tower may not be over—but it is definitively sharing the stage with something leaner, nimbler, and decidedly more human in scale.
