The launch of Base One, a 55,000 sq ft innovation hub on Portal Way in North-West London, is a small building with an outsized message: Britain's advanced manufacturing and deep tech sector has been starved of the flexible, affordable space it needs to scale, and the property industry is only now waking up to the opportunity this represents. Offering ready-to-occupy labs and offices aimed squarely at high-growth scientific companies, the scheme is being pitched as a template rather than a one-off — and the underlying economics suggest that template could be replicated across the country's second-tier cities within the next two years.
