What 3 Sphere does

3-sphere (legal entity: 3-sphere London Ltd.) is an independent Quantity Surveying and Construction Cost Consultancy founded in 2014 and headquartered in London's Square Mile, with a secondary office in Dubai Marina serving clients in the United Arab Emirates. The firm provides professional services across the full construction cost lifecycle, including pre-contract and post-contract quantity surveying (cost estimating across all RIBA stages, cost modelling, benchmarking, contract advice, procurement and tendering, final account negotiation), commercial management (capital planning, CAPEX review, facilities management procurement), specialist services (capital allowances, dilapidations, employer agent, contract administration, bank monitoring), and a dedicated sustainability practice covering LEED, BREEAM, FITWELL and WELL estimating, embodied carbon reporting, life-cycle costing, and carbon offset calculations.

The company serves commercial, leisure/retail, mixed-use, and residential real estate and construction clients across the UK, Europe, and the UAE. Its go-to-market is direct and sales-led: prospective clients initiate contact via the website form or [email protected], with each engagement scoped and quoted on a per-project basis. There is no disclosed pricing, no intermediaries, no technology platform, and no recurring-revenue product; revenue is generated entirely through project-based professional service fees.

3-sphere operates as a boutique consultancy of approximately 11 employees, relying on senior practitioner expertise rather than proprietary technology. Its stated differentiators are independence from any construction company, full-lifecycle coverage from project inception to completion, and specialist sustainability and carbon advisory credentials — an area positioned to capture growing demand from developers and lenders facing tightening ESG and embodied-carbon disclosure requirements.
