What C2N does

C2N Construction Consultants Network B.V. is a privately held Dutch real estate advisory firm founded in 2004 and headquartered at Zeestraat 66b, The Hague (Den Haag). The firm operates as a specialized consultancy delivering three integrated service lines — Sustainability Advice (Duurzaamheidsadvies), Technical Due Diligence (TDD), and Project Management — to institutional investors, asset managers, property developers, governments, and engineers across the Netherlands and, via a 400+ partner network, broader Europe. Its technical capability stack includes NEN 2767 condition inspections, BREEAM (Assessor, Expert, In-Use) certification, ESG and EU Taxonomy due diligence, CRREM (Carbon Risk Real Estate Monitor) pathway analysis, and Building Automation and Control Systems (GACS) compliance advisory under EPBD regulations.

C2N's revenue model is project-based professional services, with fees quoted per engagement based on property size, certification scope, or transaction complexity. The firm has logged 2,424 completed projects and 4.5 million m² of sustainably retrofitted or certified real estate, with marquee references spanning banking (De Nederlandse Bank), logistics (WDP, PLUS Retail, Tesla, Scania, Hoogvliet), institutional asset management (Fidelity International, Altera), public sector (Gemeente Tilburg, Universiteit Utrecht), and hospitality (Hilton Amsterdam Airport Schiphol). Distribution is direct enterprise advisory sales, supported by professional channels: a LinkedIn/Instagram content presence, annual Expo Real (Munich) participation, and a publications library covering NEN 2767, GACS, and BREEAM updates.

The firm is organized around a four-person management team (Edwin van Eeckhoven, Hans van Brakel, Lizette van der Feer, Max Hoog), operates at 11–50 employees, and is independently owned with no disclosed external investors, parent company, or subsidiaries. In 2025 it expanded beyond its commercial real estate core into the residential rental sector and scaled its BREEAM-NL In-Use partnership with WDP Nederland, adding 13 logistics assets to bring nearly half of WDP's Dutch portfolio to certified status.
