It serves public and private sector clients across nine primary verticals: residential developers and housing associations, commercial, education, healthcare, mixed use and regeneration, senior living, student accommodation, retail and industrial, and community and third sector. The firm operates from six regional offices in Kent (headquarters), Birmingham, London Bridge, Winchester, Essex, and Cambridge, with additional reach into Scotland.

The firm's technical platform rests on ISO 19650 BIM Level 2 accreditation (achieved 2017), advanced computational fire engineering using PyroSim CFD and Pathfinder evacuation modelling, and laser-scanning / Matterport photogrammetry for point cloud surveys accurate to within 1-2% on residential applications. It maintains an integrated management system certified to ISO 9001 (1996), ISO 14001 (2001), ISO 45001, and ISO 19650, and was one of the earliest UK consultancies to achieve PAS 2060 carbon neutral certification in 2022. Revenue is generated entirely through fee-based professional services engagements with bespoke project-by-project pricing; revenue figures are not publicly disclosed. The go-to-market motion is direct sales-led engagement with enterprise and public sector buyers, supported by thought leadership through LinkedIn, Instagram, YouTube podcast series including 'Hard Hats + Hot Topics' and 'The Road to 2030', CPD seminars, and active participation in industry awards (RIBA Stirling Prize 2023, CN Consultancy of the Year 2023, Property Week RESI Consultancy Practice of the Year 2024).
