The initial stations on the first MRT lines in Singapore have simple designs, with more focus on engineering and safety using simple aesthetics. One main concern back then (and still is) has been crowd movement. The size of the station platforms and the width and height of the entrances have been carefully conceptualised to ensure enhanced passenger movement in the network. Nevertheless, some of these stations have artworks reflecting the area they serve, and key features were employed for the underground stations in the
Central Business District (CBD). One example is the distinctive dome above
Orchard station, which is featured as the "showpiece" for the MRT network. Each station also has a colour scheme which distinguishes them from one another. In the later Phase II of the network, the roofs of the elevated stations have distinct designs which reflect Singapore's heritage and the surroundings, proposed by architect Scott Danielson. The
Lakeside and
Chinese Garden stations have curved Chinese roofs similar to the structures in
Chinese Garden, while
Eunos station has a Malay-style roof to reflect the locality of
Geylang Serai, a Malay enclave. The roof of
Jurong East station, meanwhile, is similar in design to the adjacent
Jurong East Bus Interchange: a
space frame roof made up of cylindrical steel tubes with ball joints arranged in a geometric style. In 2025, the LTA announced that 40 older stations on the North–South and East–West lines will gain public artworks, as part of expansion of the Art in Transit programme.
Changi Airport branch (2001) The elevated Expo station is designed by
British architectural firm
Foster and Partners. The station features two roofs overlapping one another — a
stainless-steel roof over the concourse and ticket level in diameter, and a long titanium roof stretching over the platform level. The former reflects sunlight into the concourse which minimises the need for artificial lighting, while the latter deflects sun rays, which cools the platform by up to four degrees less than its surroundings. These materials for the roof were adapted to fit into warm tropical Singaporean climate. The spacious interior of the station allows natural lighting and ventilation. The station is designed by architectural firm
Skidmore, Owings and Merrill, featuring a large interior space and an illuminated linkbridge spanning over the island platform, connecting Terminals 2 and 3 with travellators.
Australian engineering company Meinhardt Facades also provided structural design engineering of the glazing system and the tensioned cable structure of the two atria (approximately long by wide by high each) located at both ends of the station box adjacent to Terminal 2 and 3 of Changi Airport, with engineering input by
Ove Arup and Partners. In 2011, the station was rated 10 out of 15 most beautiful subway stops in the world by BootsnAll. At a height of , the three-level station has an arched metal roof supported by stainless steel columns to give a more spacious interior. The station concourse level was clad in floor-to-ceiling glass panels. The design has a nautical theme; thus, the station is shaped like a ship when viewed from the outside. This design was inspired by
Sembawang's historical role as a
British naval base. The station’s roof is modeled after wind blades to convey the speed of Singapore's
public transportation. The sides of the station were constructed using glass rather than concrete to allow natural light to enter.
Louvers were installed to provide ventilation. For the construction team's efforts to integrate landscaping and the use of eco-friendly materials, the station was awarded a Platinum certification under the
Building and Construction Authority's new Green Mark scheme for transit stations. Canberra station is the first MRT station to attain such a rating. ==North East Line==
