What Cassidy + Ashton does

Cassidy + Ashton is a UK-based multi-disciplinary professional services practice founded in 1960, operating as Cassidy + Ashton Group Limited (company number 2510645) from four regional offices: Preston, Lancashire (headquarters), London, Chester, and Mold. The firm provides four integrated service lines: Architecture (feasibility, concept design, planning applications, conservation, BIM, contract administration, masterplanning, interior design), Building Surveying (commercial and residential surveys, defect diagnosis, project management, dilapidations, party wall, expert witness, quinquennial surveys), Town Planning (planning applications, EIA, community engagement, appeals, S106 agreements), and Principal Designer services (CDM 2015 compliance). Client segments span education, local government, healthcare, commercial and industrial, residential property, ecclesiastical, heritage/conservation, and religious organisations, with named clients including Manchester Metropolitan University, Lancaster University, Blackpool Council, Preston City Council, GVS Filter Technology, and Wrightcare Group.

The practice's technical platform centres on Building Information Modelling (BIM) Level 2 using Autodesk Revit and Navisworks Manage, adopted in 2012 for 3D model-based design coordination and clash detection. The firm holds chartered practice status with RIBA, RICS, RTPI, and CIAT, plus ISO 9001 and ISO 14001 certifications and Constructionline registration, and has secured awards including a RIBA National Award (Preston Bus Station), multiple Civic Trust Awards, and RTPI Planning Excellence Awards at regional and national level (2018, 2019, 2025). Revenue is generated through project-based professional services fees (fixed fees agreed in advance, sometimes percentage-based, with stage payments), with projects ranging from £5,000 to £40 million in construction value, delivered through a four-office direct-engagement model supplemented by construction industry framework procurement access.
