The A3 building is for the department of Engineering and Technology which houses the offices and laboratories of the school, while the A4 is the lecture hall building "Cesareo Rodriguez Aguilera" in which lectures are given. Both modern and avant-garde buildings replace the iconic "experts building" located in the city centre. The aforementioned building was demolished in 2005 and in its place an El Corte Inglesshopping centre was built .
