All three metro stations sport modern variants on 19th-century station roofing. That of Centrum station is a steel barrel-vault divided into three by transverse rooflights curved inwards. Heemraadlaan station, on the other hand, is capped by a transparent vault sandwiched between two entrance slabs with facades patterned chessboard-fashion. The platforms of both stations rest on steel space frames. The De Akkers Station is hidden in a shopping centre.
