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.
