What david & on arx does

david & von arx landschaftsarchitektur gmbh is a Swiss landscape architecture practice founded in 2001 and headquartered in Solothurn, operating across Switzerland with projects in cantons including Bern, Solothurn, Aargau, and Basel-Landschaft. The firm is co-owned by founding partners Marlis David and Christoph von Arx, both dipl. Ing. Landschaftsarchitekten FH, and employs 11-13 staff including landscape architects, technical draftspeople, an apprentice, interns, and an office administrator. Its offering is organized into eight service categories: Garten (private gardens), Wohnanlage (residential complexes), Arbeitsumfeld (work environments), Park und Friedhof (parks and cemeteries), Platz und Strasse (squares and streets), Bildung und Kultur (education and culture), Spital und Heim (hospitals and care homes), and Wettbewerb (competition participation).

The firm's core technology is site-specific landscape architecture design — exterior space planning, garden design, park and cemetery planning, streetscape and square design, and therapeutic/restorative garden design for healthcare facilities. Delivery is conventional professional-services work: competition submissions (Wettbewerb), commissioned planning, and interdisciplinary collaboration with architecture partners (Liechti Graf Zumsteg, Metron AG, Gautschi Lenzin Schenker, Lüscher Egli, GSJ Architekten). The firm holds no patents, software products, or proprietary platforms; its only technology-adjacent asset is a postgraduate diploma in computer visualization held by co-founder Christoph von Arx (2000).

The business model is project-based professional services revenue. Work is acquired primarily through Swiss public-sector competitions, direct tenders, and private commissions, supported by BSLA and SIA professional-association membership and a portfolio website segmented across project categories. Pricing is not publicly disclosed; fees are determined through competition outcomes and direct commission negotiation. The customer mix is dominated by Swiss municipalities, cantons, and government institutions, supplemented by private developers, healthcare providers, and architecture firms. Revenue, ARR, and financial performance are not publicly disclosed; the firm is entirely founder-owned with no external investment, subsidiaries, or parent entities.
