What NBS does

NBS is a private construction technology company headquartered in Newcastle upon Tyne, UK, operating as Hubexo North UK Ltd within the Hubexo group (affiliated with RIBA Enterprises). Founded in 1973 and active for five decades, the company provides cloud-based specification, product information, classification, and BIM coordination software for the architecture, engineering, manufacturing, and contracting industries. Its core platforms are NBS Chorus, a collaborative cloud-based construction specification authoring tool; NBS Source, a centralized product information platform aggregating 30,000+ manufacturer products; and Lattira, a next-generation specification and product decision platform launched in the United States in February 2026. Supporting modules include NBS LCA (lifecycle carbon assessment, launched 2025), NBS BIM (3D modelling tools), Uniclass (a construction-industry classification system), the Construction Information Service (standards and regulatory content), and NBS Schumann (professional specification consultancy, acquired in 2020).

The business model is predominantly subscription SaaS. NBS charges recurring subscriptions for NBS Chorus, NBS LCA, NBS Source listings (paid by manufacturers), and the Construction Information Service, supplemented by professional services revenue from NBS Schumann. Pricing is not publicly disclosed; subscription tiers are sold on an annual billing cadence with enterprise demos available. Go-to-market combines direct enterprise field sales, particularly in the UK, Canada (Toronto), and Australia (Sydney), with a global reseller partner network (e.g., SolidCAD in Canada) and technology integration partnerships with BIM platforms including Autodesk, Graphisoft, Vectorworks, and Newforma. Marketing is content-led through the NBS Knowledge portal, the annual Digital Construction Report, NBS Academy training, and industry events.

The customer base spans two sides of a marketplace: demand-side architects, engineers, specifiers, and contractors (4,500+ companies, 275,000+ users) and supply-side construction product manufacturers (3M, Assa Abloy, Cemex, DuPont, Dyson, Formica, Hilti, Kingspan). Enterprise design firms including HOK, Arup, Aecom, BDP, Ryder Architecture, Woods Bagot, Mott MacDonald, and IBI Group rely on NBS for specification and BIM workflows. With 68,000+ specifications and 32,000+ new projects created in 2024 and 98%+ adoption among UK top architects, NBS holds a dominant position in its home UK market while executing on international expansion through Lattira in the US and continued channel-led growth in Canada and Australia.
