Malmos

What Malmos does

Malmos A/S is a Danish landscape construction company founded in 1953 and headquartered in Roskilde, Denmark. Operating as part of the idverde group following the July 2025 merger of OKNygaard Anlæg and Malmos Landskaber, the company positions itself as Denmark's largest specialized landscape construction contractor focused on establishment. Its core service lines include green roofs (including steep 45° installations using ZinCo's Georaster system), climate adaptation/LAR (local stormwater management and blue-green infrastructure), paving, planting and biodiversity enhancement, earthwork, sewer and utility work, play and movement areas, street furniture, gabions and retaining walls, and the proprietary STUB mobile temporary-landscape system.

The company's technology base is rooted in nature-based landscape engineering rather than software or AI. Proprietary or differentiated assets include the STUB mobile plant-box system (with secondary terrorsikring use), the Malmos Lab innovation unit, and the Natur+ consulting methodology launched in May 2026 that bundles nature-based advisory services — early project involvement, nature-positive area development, knowledge sharing, and documentation — with ongoing operations. Co-developed products such as Klimaflisen (with Tredje Natur, IBF, and ACO Nordic) won the Popular Science Best of What's New Grand Award in 2018. Internal digital tooling comprises BIM.5D for project coordination, Sigma for estimating, and Bluebeam for markup — none of which constitute AI-native systems.

Malmos generates revenue primarily through project-based B2B contracts awarded via competitive tendering for public and large private projects. The go-to-market is enterprise field sales targeting Danish municipalities, housing associations, and private developers/institutional investors. FY2023 revenue was 257 million DKK with 12% YoY growth, and the flagship Urbanplanen climate-adaptation project alone represents ~342M DKK over 3–4 years with housing associations 3B and KAB. Customers include Aarhus Kommune (Musikhusparken, 32M DKK), København Kommune (Bavnehøj Allé and Vestre Kirkegård, 13M DKK), Guldborgsund Kommune (Latinerkvarteret, 3.7M DKK), and Danica Pension (Kysthus 3, 20M DKK). The company operates from six Danish offices (Roskilde, Aarhus, Odense, Ubby, Aalborg, Vejle) with approximately 280 employees completing ~480 projects annually, holds B-Corp certification (2023) and ISO 14001 environmental certification, and is led by CEO Rasmus Karkov (appointed June 2026).

Core offering

Malmos is Denmark's largest specialized landscape construction company, delivering establishment-phase landscape projects including green roofs, climate adaptation (LAR/blue-green infrastructure), biodiversity planting, paving, earthwork, sewer/utility infrastructure, play and movement areas, and temporary mobile landscapes (STUB) for municipalities, housing associations, and private developers. The company operates as a total contractor combining enterprise-scale execution with gardener-level craftsmanship, pioneering nature-based solutions and early project involvement across roughly 480 projects annually.

Product overview

Malmos is Denmark's largest landscape architecture company specializing in construction and establishment services. The company operates as a unified offering with multiple interconnected service lines rather than a software platform. The core services include green roofs (Grønne tage), climate adaptation/LAR solutions, paving (Belægning), planting/biodiversity (Beplantning/Biodiversitet), earthwork, play and movement areas, street furniture, sewer work, temporary landscapes (STUB), and gabions. Additionally, Malmos offers the Natur+ service—a nature-based consulting approach that provides early involvement, nature-positive development, practice-based knowledge sharing, and documentation. The Malmoshuset visitor center serves as a showcase facility. Projects range from urban parks and climate adaptation at scale (Urbanplanen at ~342 million DKK) to specialized green roofs on steep surfaces (45 degrees) and biodiversity-restoration areas. The company also provides circular economy solutions including material reuse and recycling on construction sites.
