What WW+P Architects does
WW+P Architects, originally founded as Weston Williamson + Partners in 1985 and headquartered in London, is a global architectural, urban design, and planning practice operating through 12 studios across the United Kingdom, Canada, the United States, Mexico, Australia, China, Hong Kong, and Saudi Arabia, with over 400 architects, urban designers, and planners. The firm delivers an integrated portfolio across five core disciplines — Architecture Services, Planning & Masterplanning, Regenerative Design, Landscape & Public Realm, and Design Guidance — and five sector specialties: Transit Oriented Development, Transport & Infrastructure, Housing, Aviation, and Bridges & Infrastructure. The business model is project-based professional services delivery, with revenue derived from competitive tenders and direct client engagements rather than disclosed pricing.
WW+P's technical capability is anchored by in-house model workshops, a "Sketchbook Process" for conceptual design, and a digital/computational design team employing BIM and generative procedural modelling on large infrastructure programs such as Baiyun Metro Station and the Melbourne Metro Tunnel stations. Clients are predominantly public-sector — Transport for London (Paddington, Old Street, and Woolwich Elizabeth Line stations), HS2, Metrolinx (Ontario Line, Eglinton Crosstown), Rail Projects Victoria (Melbourne Metro Tunnel), METRONET (Perth), Greater Toronto Airport Authority, and London Boroughs of Southwark and Merton — alongside private developers such as Tridel, Arden Cross Limited, Century Group, and York Region Housing. The firm is privately held under legal entity WestonWilliamson+Partners LLP and operates as part of the 10N Collective within Egis Group, a European consulting, engineering, and mobility services conglomerate with operations in 120 countries.
In January 2026, WW+P merged with SvN Architects + Planners, consolidating under the WW+P brand within the 10N Collective platform. The combined practice pursues signature transit and housing projects globally, with recent accolades including the 2024 RIBA National Award and Prix Versailles for Paddington Elizabeth Line Station, 6 Star Green Star Design ratings on Melbourne Metro Tunnel stations, and a 2025 AJ Architecture Award for the Commercial Way affordable housing scheme. Revenue is not publicly disclosed.
