What Architects Plus does

Architects Plus (UK) Limited is a Carlisle-headquartered architectural practice founded in 1988 and incorporated in 2001, providing full-service RIBA Stages 1-7 architectural services across new build, retrofit, and refurbishment projects. The firm serves clients across eight service categories — Commercial and Retail, Education, Hotel and Leisure, Residential (private and community), Community, Healthcare and Veterinary, Heritage Conservation, and Sustainability — with notable commissions spanning housing associations, NHS trusts, universities, manufacturing firms, hospitality groups, and heritage projects. Notable projects include the £6m Lakes Distillery conversion, £19m Pirelli Tyre Factory, £4.7m University of Cumbria Fusehill Street campus, and the Carlisle Cricket Club flood restoration works.

The practice operates on a professional services revenue model with project-specific pricing across multiple sectors. Its core technology stack centres on BIM Level 2 compliant 3D parametric modelling to monitor operational and functional requirements through building lifecycles. The firm holds multiple professional accreditations including RIBA Chartered Practice, ISO 9001 and 14001, Planet Mark certification, Passivhaus Trust membership, and Carbon Literate Organisation Bronze status, signalling deep specialisation in sustainable and heritage-sensitive design. It pursues projects through direct client engagement, competitive tenders, RIBA competitions, and contractor-led Design and Build commissions, working with a stable network of contractor partners including Thomas Armstrong Construction and Lambert Gill.

The go-to-market motion is relationship-driven and regionally anchored, with a sales-led approach that leverages long-standing client relationships — notably a 20-year University of Cumbria partnership and a Home Group relationship stretching back to 2006 — alongside competitive tender processes and referrals. The practice operates across Cumbria, Lancashire, Hampshire, West Yorkshire, Gloucestershire, and Dumfries and Galloway, with its August 2024 relocation to Carlyle's Court in Carlisle supporting continued operations from its Cumbrian base. Its workforce of 11-50 employees includes qualified professionals with 10-30+ year tenures, providing institutional continuity that underpins repeat business and complex heritage and conservation work.
