LONG SPAN BEAMS – World horti center
International meeting point
Smiemans Projecten built the superstructure of the knowledge and innovation
centre “World Horti Center”. With approximately 25,000 international
professional visitors every year, it is the international platform where business,
education and government jointly innovate, connect, create and inspire. It is
also the place for a year round trade fair where more than 200 companies show
their latest innovations.

Glass construction of 12.3 meters high
The glass construction has a surface of 4,520m². The glass roof is 12.30 meters
high, this gives an impressive entrance when entering the building. Special
measures have been taken to regulate an optimal indoor climate with as little
energy consumption as possible. The height offers room for two floors with
shared facilities for ± 300 guests, such as an auditorium, meeting rooms, flexible
workstations and a restaurant. The building has a total floor area of 8,800m.

Emir of Kuwait. The ceremony was likewise attended by various ministers and
high-ranking officials of the Kuwait government.
6 different gardens and 4 different climate zones
This botanical garden is located at the Emir‟s Bayan Palace and occupies an
area of 15,793 m². Almost 3,500 m² of space is devoted to the cultivation of
various exotic plants in the glasshouse. Despite temperatures hitting peaks of 53
degrees Celsius outside, the indoor climate is carefully controlled.
With innovative climate systems and high-quality installations, we can properly
regulate the temperature and humidity, which means that plants from all over
the world can be found in this beautiful enormous botanical garden.

PORTAL FRAMES – Wildlands adventure zoo
Two projects for new zoo Wildlands
At the tropical adventure park Wildlands you can visit „Rimbula‟. This huge glass
construction is the new home for birds, monkeys and elephants. At around two
hectares in size, 23 metres in height and situated 4 metres under the building
line, this enormous glasshouse is unique in Europe. Smiemans is responsible for
the 6,200 m² curtain wall, made from polycarbonate because of its excellent
insulation properties, transparency and favourable pricing.

Butterfly temple with large farming areas
The smaller glasshouse of 1,100 m² has a higher section accommodating a
butterfly house and a habitat for other reptiles, as well as a lower section which
is 200 m² in size. This is intended for the cultivation of plants, caterpillars and
butterflies. Smiemans built the whole project: the steel construction work, the
curtain walls and the roof.

Imitation of Tropical climate with enough daylight
The greenhouse construction was provided with a special 3-layer ETFE foil
(inflatable cushions). This special foil allows not only daylight, but the complete
light spectrum. In addition, the system offers excellent insulation, allowing the
tropical climate to be well simulated. These matters are essential for tropical
plants and animals in the greenhouse. One really experiences the feeling of
being outside!
