The builder of innovative and inspiring garden centres and other glass constructions

Garden centres, botanical glasshouses, leisure centres...

Our modern, independent and family-owned company, with our roots in the development of greenhouses, realizes all types of commercial glass constructions, like futureproof and tailor-made garden centres and botanical glasshouses. Our company has been in the limelight for years, attracting customers and the media with our elegant, curved "HighLight"-glasshouse system. But apart from that, we also develop and build many other innovative systems and constructions.

Transparant buildings that enhance the value of your brand, product or project

Choosing Smiemans for engineering and building your project means choosing quality and innovative (glasshouse-)technology. Innovation is a key issue; at Smiemans, it is part of our daily work.

High-profile glass structures

High-profile projects, like Floriade, World EXPO and Keukenhof, as our forerunners in building glass constructions. This rich history ensures that with our vision and skills we realize future-proof and tailor-made greenhouses.

For many different clients we realized glass constructions for various sectors; from zoo to restaurant, from atrium for an office building to knowledge centre. Every system has its advantages; Venlo, wide span and our own 'SP small span' and "HighLight" curved constructions.

Smiemans "all-in" greenhouse BV was founded in 1974 and changed to Smiemans Projecten BV in 1986.



In 1991 we moved to the former vegetable auction in Kwintsheul, a characteristic building with expansion possibilities.



Shortly thereafter, subsidiary Allicon Alluminium Lichtconstructies was established for curtain walls and skin facades



For the Keukenhof we built a pavilion with an arch construction, a concept that had never been shown before.



Portalume is established to develop aluminum doors and windows.



For the Floriade we realized the largest solar panel roof in the world in 2002.



In 2003 Jeroen took over the company Smiemans Projecten from his father Joop.



EdenParks was founded as the new brand for the more exclusive glass constructions.



In 2022, TC Projects was established to meet Dutch and Belgian customers' demand for turnkey projects.
