What Wonam does

Wonam is a privately held Dutch real estate developer and investor founded in 2011 and headquartered in Amsterdam. The company develops, invests in, and manages affordable rental housing through both new construction and office-to-residential transformation, with its core geographies in the Amsterdam and Utrecht regions and additional projects in Haarlem, Houten, and Zoetermeer. Wonam operates across the full real-estate value chain — from land acquisition through municipal tenders, through project development, to long-term ownership and asset management of select portfolios. Its clients comprise housing corporations (Woonin, Portaal), institutional real estate investors (NLV, Woonhave, Orange Capital Partners, Great Grey Investments, Greystar), municipalities (Amsterdam, Utrecht), and end tenants that include starters, families, healthcare and education workers, and vulnerable populations served via partners such as Leger des Heils. Wonam is a member of IVBN (the Dutch association of institutional real estate investors).

The portfolio consists of 14 named projects ranging from mid-size residential buildings (~62 units, e.g., Willem) to large mixed-use developments (592 apartments plus ~19,000 m² of office and commercial space at The Ensemble). Flagship projects include Zandkasteel — the transformation of the former ING headquarters into 263 rental apartments, 47 offices, and 1,200 m² of hospitality, which won the Geurt Brinkgreve Bokaal 2023 and now also houses Wonam's own headquarters; Mookly, a 281-home gas-free, nature-inclusive development in Amsterdam Amstelkwartier with 1,350 solar panels, 250 nest boxes, and 450 m³ of rainwater storage; BLOEI 030, a 264-home mixed-tenure co-development with housing corporation Woonin and builder Heijmans; BUUR, a 454-home mixed-tenure project with Portaal that won the Middenhuur Award 2021; and The Ensemble (BREEAM Excellent for its office space). The technical focus is on sustainable building rather than software: nature-inclusive design (micro-forests, green facades, biodiverse rooftops), gas-free all-electric construction, district heating and cooling connections in every project since founding, high insulation, solar panels, rainwater harvesting, circular materials, and biobased construction. Wonam co-developed the 'Bruto Impact Rendement' (BIR) methodology with Impact Institute and Homevest to quantify environmental and social outcomes alongside traditional financial metrics, and is a partner of the Dutch Green Building Council.

Revenue is generated through four streams: (1) residential rental income from owned portfolio — notably the 263 Zandkasteel units priced at €810–€1,490/month and Silva's 131 units from €834/month; (2) owner-occupied home sales, e.g., the 35 koopwoningen retained at Mookly for forward sale; (3) commercial space rental — 47 offices and hospitality at Zandkasteel, ~19,000 m² at The Ensemble, plus assorted ground-floor retail and office space across other projects; and (4) delegated development and asset management fees earned on projects handed to institutional partners (e.g., NLV at Mookly, Orange Capital Partners at KARSP!, Woonhave at BUUR and WILLEM). Wonam acts as both principal developer and delegated developer for third parties. The team is compact at 11–50 employees, led by directors Robert Kohsiek, Carolyn van Duijvendijk, Melanie Egberts, and Gerard Kohsiek. Revenue, profit, ownership structure, and funding history are not publicly disclosed.

Properties include middenhuur (middle-rent) apartments rented directly to tenants at publicly advertised prices (e.g., €810–€1,490/month for Zandkasteel; €834+/month for Silva). Wonam also invests in and manages rental portfolios for long-term institutional investors and for their own account.
2. Owner-occupied home sales: Wonam develops and sells owner-occupied homes (koopwoningen) such as the 35 luxury homes at Mookly project. Revenue from sales is realized upon handover to buyers.
3. Asset management fees: Wonam manages joint ventures and asset management for residential buildings they have developed, earning management fees. They are a member of IVBN (Vereniging van Institutionele Vastgoedbeleggers in Nederland), indicating institutional investor relationships.
4. Commercial space rental: Wonam generates rental income from commercial spaces in the plinth of their buildings — horeca (e.g., D.E. Café in Zandkasteel), artisanal workshops (Artisan in BUUR), office spaces (47 offices in Zandkasteel, 19,000 m² in The Ensemble), and other commercial units.
