LOF Landschapsarchitecten

What LOF Landschapsarchitecten does

LOF Landschapsarchitecten is a privately held Dutch landscape architecture firm headquartered in Utrecht at Doelenstraat 32, operating across the Netherlands. Founded in 2006 as Feddes/Olthof Landschapsarchitecten by Yttje Feddes and Berdie Olthof, the firm was rebranded to LOF on February 2, 2025 coinciding with the succession of partners Yoran van Boheemen and Femke Visser. The firm employs approximately 10 landscape architects, designers, and a bureau manager, augmented by occasional interns, and serves exclusively Dutch government clients — municipalities, provinces, water boards (waterschappen), and national agencies such as Rijkswaterstaat.

The firm's service portfolio spans landscape architecture and design from vision to implementation, organized around five core service modules: spatial vision and design research (Ruimtelijke Visie en Ontwerpend Onderzoek), regional area analyses (Gebiedsanalyses), implementation plans (Inrichtingsplannen), and climate adaptation planning. Its competitive approach, branded internally as the 'integral design approach,' connects landscape architecture with technical disciplines — integrating water storage into park designs, biodiversity into urban plans, cultural-historical restoration into dike reinforcement, and energy infrastructure into coastal defense. Visualization is central to the firm's methodology: maps, renderings, and models are used to make future spatial scenarios legible for clients, stakeholders, and decision-makers, supplemented by collaborative design workshops and kitchen-table stakeholder dialogues.

LOF generates revenue through project-based professional services contracts awarded via Dutch public procurement and direct government engagement. Projects range from vision documents and area analyses (such as the Groenblauw Raamwerk Rivierenland for Regio Rivierenland and the UNESCO-related Gebiedsanalyses Hollandse Waterlinies for Provincie Noord-Holland) to flagship implementation works including the 72km-long Het langste beplantingslint van Nederland for Rijkswaterstaat, the Piekberging Haarlemmermeer flood-water storage for Hoogheemraadschap van Rijnland (winner of the Arie Keppler Prize 2024), and the Vismigratierivier fish migration river for Provincie Fryslân. The firm consistently collaborates with external partners including Paul de Ruiter Architects, Bulter architecten, Deltares, and Studio Ossidiana on multi-disciplinary consortia. Pricing is not publicly disclosed; fees are negotiated per project through standard Dutch government procurement channels, and contract durations are typically multi-year.

• Sweco: Sweco's Dutch practice offers landscape, urban design and water management consulting to government clients. As a large European incumbent, it competes with LOF on integrated climate and water commissions and represents the upper bound of scale competitors in the Dutch market.
• West 8: West 8 is one of the largest and most internationally recognized Dutch landscape architecture firms with offices in Rotterdam and globally. It competes with LOF on flagship Dutch public and waterfront projects but operates at materially larger scale and with broader geographic reach.

Direct peers

• HOSPER: HOSPER is a Dutch landscape architecture and urban planning firm of comparable size based in Houten, Netherlands.

• H+N+S Landschapsarchitecten: H+N+S is a Dutch landscape architecture firm specialized in climate adaptation, water systems and regional planning. Its core focus on integral climate and water-driven design closely mirrors LOF's positioning around waterboards and climate programs like RES and Piekberging.
• Karres en Brands: Karres en Brands is a Netherlands-based landscape architecture and urban design firm working on public space, climate adaptation and regional planning. It competes with LOF for the same Dutch government and water-board commissions and shares the integral design ethos.
• OKRA Landschapsarchitecten: OKRA is a Utrecht-headquartered Dutch landscape architecture firm working across public space, climate adaptation and water projects. Its geographic base and integral approach make it a close comparable to LOF in both Dutch B2G landscape work and design methodology.
