What Smiemans Projecten does

Smiemans Projecten B.V. is a Dutch family-owned specialty construction company founded in 1974 that designs, engineers, and delivers custom glass and aluminum structures for garden centres, botanical gardens, zoos, universities, healthcare facilities, and cultural institutions. The company operates three proprietary construction systems — Venlo Plus (economical standard greenhouse), Wide Span (long clear-span modular), and HighLight (curved modular arches) — alongside the Roll-Air Retail openable-roof module supplied exclusively through a partnership with Rovero Systems. Integrated climate control, screening, 3-layer ETFE foil, asymmetric PV-roof structures, and Hydro CIRCAL-certified sustainable aluminum form the technical backbone. Operations are organized around three wholly-owned entities: Allicon Aluminium Lichtconstructies (curtain walls/canopies, est. 1991), EdenParks (high-end botanical and monumental projects, est. 2014), and TC Projecten (turnkey garden centre delivery in Benelux, acquired 2022). Revenue is generated primarily through one-time custom construction projects (large-scale, multi-year contracts with installation and CE 1090 certification per project), supplemented by recurring periodic maintenance contracts and EdenParks design/consultancy services. The company goes to market through direct enterprise field sales, an active trade fair presence (GLAS, GLEE, IPM, Trade Fair Aalsmeer, Global Garden Retail Conference), and a network of regional channel partners in the UK, Ireland, the USA, and Benelux. Project pricing is quote-based with free initial design consults; no standardized pricing is publicly disclosed. Customer concentration sits in garden centre retail (primary) and botanical/cultural institutions (secondary), with named projects such as Plantorama, RHS Wisley, Keukenhof, Wildlands Zoo, and Bayan Botanic Garden Kuwait.
