The mixture of factory building, warehouse and admin for a glass-processing company was built on an L-shaped ground plan. The three-storey building accessible by lorries is the heart of the steel skeleton structure. It is for warehousing and glass production and light gets in from all sides because
the glass theme doesn’t only characterise the structure’s use but also the curtain facade made of slaps of various sizes, quality and colour. More than twenty different kinds of glass were used, varying by colour, energy perviousness, durability and price. The quantity of glass used is also the client’s advertising medium.
Ventilation is provided by non-transparent zones with metal hatches so narrow that they don’t require a safety parapet. The outer skin is thus completely planar.
The impression one gets inside is rather that of a greenhouse. The building has a very light and inviting atmosphere.
There are six rental offices, all comprising one storey. They are designed as lavish offices, but can subdivided by partitions. The office floors are accessible by two access cores, which also lead down to the spacious underground garage.
In the basement, slanted concrete pillars correspond to the steel supports of the upper floors. Just like the oblong glass areas characterise the facade on the outside, the supports are a consistent design element inside.
