What Greenhouse Advies does

Greenhouse Advies B.V. is a Dutch multidisciplinary environmental and advisory firm headquartered in Huissen, Netherlands, founded in 2009 and operating as a core subsidiary of DAGnl (De Adviesgroep Nederland), a network of 11 specialized engineering and consulting firms with 200+ colleagues across 9 locations. The firm delivers project-based advisory across five interrelated disciplines: archaeology (desk-based research, borehole investigation, trial trenching, excavation, supervision, and project management under BRL 4000 certification), asbestos inventory and removal management (performed by certified DIA professionals), soil investigation and remediation (quickscans, risk assessments, and environmental supervision under SIKB-BRL 6000), environmental advisory (air, noise, dust, light permitting), and sustainability/energy transition consulting (GPR Gebouw methodology, SDE+ subsidy advisory, circular construction, energy-neutral building). Its operating model is B2B professional services sold directly to project developers, municipalities, provinces, water boards, and heritage property owners, with payment terms of 30 days under DNR 2011 and AV DAGnl 2023 conditions and quote-based, project-specific pricing.

The firm's competitive positioning rests on three pillars: (1) regulatory certifications that legally gate Dutch environmental and archaeological work, including being the first company without a prior excavation permit to achieve BRL 4000 certification, plus ISO 14001 environmental management and pursuit of CO2-Prestatieladder Level 3; (2) staff with prior experience across the client, contractor, and regulatory authority roles, providing cross-stakeholder project perspective; and (3) integration within the DAGnl network, enabling cross-discipline delivery through sister firms specializing in civil engineering, surveying, urban planning, and explosives investigation. Customers are concentrated in Gelderland, Utrecht, Overijssel, and Noord-Brabant, with named engagements including Gemeente Eemnes (climate policy), Park Lingezegen (1,500-hectare regional park archaeology), Park 15 (85-hectare business park with Roman cemetery and Bronze Age settlement findings), and a Lochem-area farmer (141 kWp solar roof producing 130,000 kWh annually under SDE+).

Revenue is generated entirely through professional services fees for investigations, assessments, project management, and advisory work, with no disclosed figures, no funding rounds, and no M&A activity. Marketing is primarily through the company website, Facebook and Twitter presence, and industry event participation including the Infra Relatiedagen trade fair in Hardenberg. The firm is privately held with no venture capital, private equity, or public ownership indicated.

Product overview

Greenhouse Advies is a multidisciplinary engineering and advisory firm (onderdeel van DAGnl, De AdviesGroep Nederland) offering a broad portfolio of interconnected environmental and construction advisory services. The firm operates as a single integrated offering rather than a platform-plus-modules architecture. Its services span the full project lifecycle — from initial research (quickscan, feasibility studies) through planning, permitting, and execution — across disciplines including archeologie (archaeological research and excavation), asbest inventarisatie (asbestos inventory and removal management), bodemonderzoek (soil investigation), bodemsanering (soil remediation and environmental supervision), milieu (environmental advisory), duurzaam bouwen (sustainable construction advisory), duurzame energie (sustainable energy and subsidy advisory), projectmanagement, projectontwikkeling (project development for brownfield sites), and nazorg (aftercare of remediated sites). Services are delivered by multidisciplinary teams drawing on DAGnl's network of sister companies, enabling clients to work with a single contact point across multiple disciplines.
