What Gustafson Porter + Bowman does

Gustafson Porter + Bowman is an international landscape architecture practice founded in 1997 by Kathryn Gustafson, Neil Porter, and Mary Bowman and registered as a limited liability partnership in England & Wales. The practice is headquartered in London and delivers a full range of services including concept design, masterplanning, detailed landscape design, and construction-stage supervision across commercial, residential, public-realm, parks and gardens, plaza, and cultural-heritage project types. The firm has completed award-winning projects across the United Kingdom, Ireland, continental Europe, the Middle East, East Asia, and North America, with notable commissions spanning the Diana Memorial Fountain in London, Cultuurpark Westergasfabriek in Amsterdam, Old Market Square in Nottingham, Marina One in Singapore, Taikoo Place in Hong Kong, Site Tour Eiffel in Paris, Bolands Mills in Dublin for Google, and Chelsea Barracks in London for Qatari Diar.

The practice operates as a professional services firm with revenue generated through fees on landscape architecture commissions, acquired via competitive tenders and public procurement, direct commissions from developers and government clients, and repeat engagements with established clients such as Google, Swire Properties, Lendlease, Argent Related, HM Treasury, and the London School of Economics. It runs as a horizontal, partner-led practice structured around typologies (Culture + Heritage, Parks + Gardens, Plazas, Masterplans, Public Realm, Residential, Commercial) and is registered with the Landscape Institute (No. 839). The firm is privately held with no external equity ownership identified, employs 11–50 staff, and serves enterprise and government customers across commercial real estate developers, residential developers, the public sector, and large-scale urban masterplanning clients.

Underlying expertise is in the integration of complex landscape features — water elements, sculptural landforms and planting — with architecture and heritage contexts; the firm has used software-scripted slope calculation to optimize earthworks on projects such as Santa Giulia, Milan. Its go-to-market relies on project portfolio marketing (website and downloadable project sheets in multiple languages), professional awards and competition wins, and participation in industry events such as the Chelsea Flower Show, supported by an extensive and widely recognized body of completed work.
