HAL Allergy is a company that is specialized in the production of allergen extracts, for both treatment and diagnostic applications. Here approximately 110 employees work on development, production, quality control and management, clinical business and registration. HAL Allergy's previous accommodation was situated at an city-centre location in Haarlem. This location will be redeveloped in the future. The various company departments were housed in separate buildings, which had been bought up over the course of time. These buildings were antiquated and together presented a fragmented image, where the logistic processes were unclear and where it was increasingly difficult to comply with the requirements and regulations (GMP) that were becoming stricter.
The new-build is in Leiden. The Bio Science Park is located here, with the University of Leiden and many other biomedical and related companies. HAL Allergy is situated close to the Silvius laboratory on the north side of the Bio Science Park.
The HAL Allergy building is divided into two volumes: a two-storey production building and a five-storey office and laboratory building. In between the two buildings there is quiet inner area, where both entrances are located. The buildings have been designed as independent volumes. In spite of that, the aim has been to create unity in appearance and materials, so that HAL Allergy is given a recognizable face in the Bio Science Park.
HAL Allergy's core activities, the production areas, are situated in the low production building. A sterile lab, some offices, a warehouse and dispatch are also located here. The building has a clear floor plan, which makes for good orientation in the building and allows the logistic processes to take place easily. The volume contains two main parts: a production hall with a large cleanroom plus technical loft and a narrower zone where the stacked warehouse is located. Both parts are held together by the same façade.
Between the warehouse and the production areas there is a light corridor, which plays a crucial role. It forms the transition between the two functional blocks and therefore marks the division between 'dirty' and 'clean' areas in the building. The corridor also provides orientation and light next to the 'poky' cleanroom. The cleanroom is a box within a box. It has a detached position in the hall, to keep a service zone free and create an air buffer. By giving the façade on the west, north and east sides a curved window, this space also acquires a 'face' for the outside world.
All the entrances to the building are located at the front. The main entrance is in the south elevation and consists of a double-height hall. From there, via the changing rooms, people can access the production areas and the lunch area or go to the warehouse. The dispatch entrance is situated on the east side of the building. A delivery road will be situated here on the site. Most of the parking spaces are on this side as well. With the position of the entrance hall and the large openings in the façade, the building is clearly oriented towards the street and its own forecourt. These openings allow a glimpse of the HAL Allergy's core activities, which take place in the cleanrooms. The technical loft is also visible.
