For its research center, Baxter chose the Parc de l'Alliance. The project assembles 2 former offices, integrating state-of-the-art and very specialised equipment. The headquarters consist of an office wing and a laboratory wing connected by a covered walkway that also includes a cafeteria. The cafeteria seats 200 people, and has a kitchen for 400 meals per day. Other facilities include a laundrette, a car wash, a sowing service and photo development service.

The top floors of the R&D department house various laboratories and offices for the researchers. The basement consists of a depot and plant rooms. Behind the R&D building, large climatic chambers, the largest in Europe, rise from -2 up to the ground floor  -  11 metres in all. The other wing contains mostly offices, the main entrance, 10 meeting rooms and a fitness.

Two underground levels, for technical facilities and parking, extend over the entire surface of the wings and the surrounding esplanade. The roof consists of a metal frame covered with steel plates.

Building services include the usual applications, such as motion detection and daylight detection for lighting, heat recuperation of the ventilated air for the parking and depot, … But also some very specific building services were applied: a very strict access control system, and energy friendly climatisation system. Also, the energy of highly performing exhaust hoods is reused to preheat the incoming air.
