One Creative Environments

What One Creative Environments does

One Creative Environments Ltd. (ONE) is a UK-based multi-disciplinary design consultancy founded in 1992 and headquartered in Worcester, operating additional offices in Birmingham, Cardiff, and London. The firm provides integrated architecture, civil and structural engineering, building services (MEP), landscape architecture, interior design, masterplanning, urban design, sustainable design, BIM, digital estates, and project management services delivered through a single in-house, single-point-of-contact model across all RIBA Stages 1–7. Its technology backbone is BIM Level 2 with Revit-based 3D coordination, supported by digital twin, thermal/daylight modelling, and environmental engineering workflows; ONE is certified to BIM Level 2, is RIBA Chartered, and is a Certified B Corporation.

ONE generates revenue through project-based professional services fees negotiated per commission rather than standardised pricing, serving enterprise clients across healthcare (NHS trusts, hospices), education (universities, colleges), industrial and manufacturing (food processing, automotive), secure facilities (Home Office, MoJ), government (local authorities, foreign governments), commercial, and residential sectors in the UK and internationally (Falkland Islands, Gibraltar, China, Nigeria). The firm has delivered building designs totalling £1.3 billion in construction value over the last ten years and maintains direct enterprise sales channels via competitive tenders, framework agreements, and main-contractor appointments. In April 2026, ONE was acquired by Cornerstone Group as part of a double acquisition that expanded Cornerstone into full multi-disciplinary professional services, integrating ONE's M&E, BIM, and digital-twin capabilities into a larger national platform.

Core offering

One Creative Environments is a multi-disciplinary integrated design consultancy delivering architecture, masterplanning, landscape architecture, interior design, civil and structural engineering, building services (MEP), sustainable design, BIM, digital estates, and project management as a unified in-house offering. The team operates at the forefront of BIM Level 2 workflows, providing a single point of contact to enterprise and public-sector clients across RIBA Stages 1-7, with an award-winning digital twin capability supporting building performance and asset management.

Product overview

ONE Creative Environments operates as a multi-disciplinary integrated design consultancy offering a unified platform of services centered on BIM (Building Information Modelling) methodology. The portfolio encompasses architecture, masterplanning, landscape architecture, interior design, civil and structural engineering, building services (MEP), sustainable design, digital estates, and smart assets. The core differentiator is the integrated team approach where architects, engineers, and designers work collaboratively in a 3D BIM environment from the earliest design stages through to construction and asset management. Services are delivered as a unified offering rather than separate modules, with clients benefiting from a single point of contact across all disciplines. Notable specialized offerings include Digital Estates (digital twin technology), BIM Level 2 certified delivery, and award-winning mechanical and electrical engineering services. The company recently expanded into full multi-disciplinary professional services through acquisition by Cornerstone Group while maintaining its integrated service delivery model.
