Grunplan Gmbh

What Grunplan Gmbh does

Grünplan Gmbh is an Austrian engineering and landscape architecture firm (Ingenieurbüro für Landschaftsplanung und Landschaftsarchitektur) founded in 1992 by Werner Sellinger, headquartered at Rohrbacher Straße 10 in Leobendorf (Lower Austria) with a secondary office at Warwitzstraße 9 in Salzburg. The firm delivers climate-resilient landscape architecture and environmental consulting services to municipalities, real estate developers, social housing associations, educational institutions, and commercial enterprises across Austria, with documented project activity in Lower Austria, Salzburg, Vienna, Burgenland, and Upper Austria. Its work covers the full project lifecycle from feasibility and analysis through design phases (LPH1–LPH9) to construction supervision (ÖBA), organized around five service pillars: KLIMAFIT (climate adaptation including building greening, microclimate simulation, rainwater management, unsealing/de-paving, and biodiversity), PLANUNG (full-service landscape architecture planning), UMSETZUNG (construction management and site supervision), BERATUNG (advisory services including funded consulting programs), and STUDIEN (research and innovation).

The firm holds several scarce advisory credentials that gate Austrian green-building certification pathways: it is authorized to issue GREENPASS climate performance certifications, is a registered GRÜNSTATTGRAU specialist advisor for building greening, and is an OekoBusiness Wien advisor for the BiodiversitätsFit! program. Grünplan actively participates in the development of Austrian standards ÖNORM B 1131 (building greening) and ÖNORM L 1136 (vertical greening), and it is a consortium partner in multiple FFG-funded research projects (Grau für Grün-Blau, ResourceRevival, Textil-RE-acts) investigating greywater reuse for public green spaces, resource-recovery-oriented neighborhood redevelopment, and textile-reuse retrofits. Comparable certifications achieved include three klimaaktiv Gold projects (with a perfect 1000/1000 score on Windkraft Simonsfeld), multiple GREENPASS Silver projects, and the Goldener Igel 2024 (Golden Hedgehog Award) for the IGL-Park in Korneuburg.

Grünplan operates a project-based professional services model under Austrian engineering fee structures (HOAI/LHONORM), supplemented by subsidized consulting programs distributed through state-funded channels (OekoBusiness Wien, NÖ Wirtschafts- und Tourismusförderung). Projects are acquired through direct client engagement, public procurement tenders, and architectural competitions; the firm ranked 33rd of 738 in the 2021 Competitionline landscape architecture ranking and serves a mix of public-sector and enterprise clients including Stadtgemeinde Korneuburg, Stadtgemeinde Tulln, Arbeiterkammer Wien, ARE Austrian Real Estate, GEWOG Arthur Krupp, Windkraft Simonsfeld AG, Erzdiözese Salzburg, Schönbrunn Group, and IST Austria. The business is privately held by its founder with no external funding, supported by a small team of approximately 9 professionals based in two offices; pricing is quote-based and not publicly disclosed.

Scale indicators7 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Sweco: Nordic-headquartered engineering and design consultancy with extensive European operations and growing climate adaptation services. Comparable as a broad incumbent likely to compete for Austrian and DACH-region climate-resilient urban infrastructure projects that overlap with grünplan's specialization.
• Ramboll: Global engineering, architecture, and sustainability consultancy with a significant landscape architecture and climate adaptation practice. Comparable as a broad incumbent competing for climate-resilient urban planning mandates that overlap with grünplan's niche, but operating at much larger scale across geographies.

Direct peers

• Latz + Partner: German landscape architecture firm with a strong reputation in large-scale landscape and urban regeneration projects. Comparable to grünplan as a DACH-region boutique landscape architecture peer competing in the same competition and award circuits (e.g., ELCA, Competitionline).
• Topotek 1: Berlin-based landscape architecture firm known for high-profile public space and competition-winning projects. Directly comparable to grünplan as a Competitionline-ranked, competition-driven German-speaking European landscape architecture firm of similar boutique scale serving municipalities and developers.
• GRÜNSTATTGRAU: Austrian green building and green infrastructure consultancy headquartered in Vienna. Directly comparable to grünplan as a domestic peer in building greening advisory; the two firms are also research partners on the FFG-funded Grau für Grün-Blau project, confirming overlap in methodologies, certifications, and target clients (municipalities, developers).

Regional players

• Hager Partner: Zurich-based landscape architecture firm active across Switzerland and internationally. Comparable to grünplan as a small, competition-driven DACH-region landscape architecture peer with comparable boutique scale and public-space expertise; geographic non-overlap makes it a regional rather than direct competitor.
• Gross Max: Edinburgh- and London-based landscape architecture practice with a strong competition portfolio. Comparable to grünplan in boutique scale, competition-winning positioning, and engagement with public-sector climate-resilient design — but operating primarily in the UK rather than the DACH region.
• WES & Partner: Hamburg-based landscape architecture firm with a strong portfolio in waterfront and public-space projects. Comparable to grünplan in boutique scale, German-speaking marketplace, and public-tender orientation; regional rather than direct given differing geographic footprint.
• realgrün Landschaftsarchitekten: Munich-based landscape architecture firm with comparable DACH boutique positioning and focus on ecological, climate-resilient public space. Comparable in scale and methodology orientation to grünplan, with primary geographic focus in southern Germany rather than Austria.

Emerging players

• e7 energy & sustainability consulting: Austrian energy and sustainability consultancy that collaborates with grünplan on FFG research (ResourceRevival, Textil-RE-acts, Grau für Grün-Blau). Comparable as a Vienna-based niche player in climate-resilient project consulting, but focused on energy systems rather than landscape architecture — adjacent overlap.
