Coöperatie Stek

What Coöperatie Stek does

Coöperatie Stek is a Rotterdam-based entrepreneurs' cooperative (Coöperatie STEK u.a., KVK 57467870) that designs and implements nature-rich urban green spaces for residential, commercial, and public-sector clients in the Netherlands. The cooperative is composed of nine named green professionals spanning garden design, ecology, biology, urban planning, interior design, and visual arts, who collectively deliver garden design, planting plans, rooftop and facade greening, public space projects, interior greenery, and ecological maintenance. Its core methodology, the branded "Natuurrijke Ontwerpprincipes" framework, integrates soil conditions, native plants, biodiversity, climate adaptation, and client preferences into a single ecologically grounded design process.

Revenue is generated through a combination of professional service fees (€67.50/hour for execution, €95/hour for advisory, €475+ for coaching packages, €570+ for planting plans, €1,425+ for complete garden designs), structured educational courses (€500 for a five-evening design program), and retail product sales through the Stadstuinwinkel—a physical garden center in central Rotterdam (Nieuwe Binnenweg 195b) offering biological plants, seeds from De Bolster and Cruydthoeck, soil products from Bio-Kultura, sustainable tools from Smederij De Wit, animal-attraction items, and gift vouchers. Go-to-market is sales-led and community-anchored: customers are acquired via face-to-face consultation, the physical storefront, participation in local festivals and seed-exchange events, word-of-mouth referrals, and organic social media on Instagram, Facebook, and LinkedIn. The cooperative serves a hybrid segment mix—primarily residential property owners, but also public institutions (e.g., Hoogheemraadschap van Schieland), commercial clients (horeca, offices), housing associations, and schools—with active project footprints in Rotterdam, Delft, and Schiedam.

The business is privately held under a Dutch cooperative structure with no external investors, no parent company, and no disclosed funding rounds; ownership resides with the member entrepreneurs. The organization holds no patents or trademarks and operates without an app, public API, or disclosed AI/ML capabilities. Its competitive differentiation rests on the multidisciplinary talent pool, the documented ecological design methodology, a tangible portfolio of completed urban projects (including facade gardens, rooftop installations, neighborhood greening, and educational gardens), and an integrated retail-plus-services model that anchors it within the Rotterdam urban-greening community.

Broad incumbents

• ID Verde: Major European landscaping services group with significant Dutch operations providing design, build and maintenance for public and commercial green spaces. Comparable services but at a much larger, multi-country scale relative to Stek's local cooperative model.
• Copijn Groenzorg: Established Dutch landscaping and garden-design firm offering design, construction and maintenance across a much larger footprint than Stek. Comparable service line-up but at greater scale and with a more generalist positioning.

Regional players

• Voedseltuin Rotterdam: Rotterdam-based community food-garden that recently co-hosted a seed exchange event with Stek. Operates an urban greening/community-garden mission in the same Rotterdam catchment as Stek.
• DakAkker: Rotterdam-based rooftop food farm that is also a supplier and collaborator of Stek. Operates an urban-agriculture model on a Rotterdam roof, comparable to Stek in city-greening mission and Rotterdam footprint.

Direct peers

• De Dakdokters: Dutch rooftop greening specialist offering design, installation and maintenance of green roofs across the Netherlands. Directly comparable to Stek's rooftop and facade-garden work for both residential and commercial clients.
• Buro Bobeldijk: Dutch landscape-architecture studio delivering nature-inclusive design for public, residential and corporate clients in the Netherlands. Comparable in ecological design orientation and Dutch project portfolio to Stek's work.
• Groendakspecialist: Existing co-development partner of Stek on the Daktuin Delft project. Specialises in green-roof installations with sedum, wildflower mats and rooftop gardens — directly overlapping Stek's urban greening services.

Others

• NL Greenlabel: Dutch sustainability label and ecosystem for green-sector companies, promoting nature-inclusive design and biological cultivation — themes central to Stek's value proposition. Adjacent enabler/ecosystem rather than direct competitor.
