The SP Small Span’ (triples®) construction is a combination between optimal technics to create a cost efficient light building.


Various possibilities

SP small span has a large range of options; different types of deck, various widths and heights, many possibilities in terms of glass thickness, etc. Superior material and processing quality is combined with unparalleled system diversity. Every wish comes true, whether it concerns garden centres, botanical greenhouses or the very special requirements of greenhouses in plant research.

Largest roof with solar panels in the world


Already in 2002 we built the SP small span as a PV roof for the Floriade. Almost 30,000 m² semi-transparent solar panels were placed on the roof. The 19,000 panels deliverd a photovoltaic generation capacity of 2.3 MWp. At that time it was the largest roof in the world. 


Added value for garden centres

The SP small span offers a lot of possibilities for garden centres, botanical gardens, etc. By adjusting the height and the roof covering, the function of the greenhouse can be changed from a sales area to a storage area. Good examples are garden centres Van Hage and Billig Blomst Næstved.

Numerous advantages

The SP small span construction is a very efficient construction to cover a larger surface. The possibility of omitting columns will create a large space that can be flexibly arranged. Columns can vary in heights, creating a lot of volume or, on the contrary, intimate spaces, as we did for the new office of VB. This atrium will be a place to work and socialize, but can also be used for presentations and meetings.
