The building occupies a portion of the hillside at the rear of the Institute of Hygiene and Tropical Medicine, located in Rua da Junqueira, in Lisbon. The services provided by the laboratory range from the creation and maintenance of rodents to experimental procedures.
The front of the building borders the street in front of the main building of the institute and, at the back, it is partially buried in the slope that inclined from south to north and from west to east. It has a semi-buried ground floor and two upper floors. The top floor is intended for technical areas and is covered by slabs on two levels.
The building is subdivided into two structural blocks. It is made of framed reinforced concrete structures with beams, columns and core walls, defining a regular grid. The current solution for the floors is made up of reinforced concrete conventional slabs supported on the beams. The roof slabs of the technical floor are prestressed inverted T-beams with clay hollow block in-fills.
Shallow foundations by footings were adopted.
