Structure Tone revenue almost triples to record £449m

Fit-out specialist Structure Tone nearly tripled revenue last year on the back of the London fit-out boom.
The firm, owned by US-based STO Building Group, saw turnover jump to a record £449m in 2025 from £157m a year earlier, while profitability was restored as pre-tax profit climbed to £12.6m from £1.7m.
Joint managing director Matt Blowers said growth was driven by strong demand across London’s legal, technology, financial services, media and professional services
