The station building is located on the north side of Eglinton Avenue West between the entry and exit ramps for
Allen Road. The station currently has two levels: street level and the platform level for Line 1 trains. The station's pedestrian entrance, the station concourse and a bus terminal are all located at street level. The bus terminal, located in a fare-paid area, surrounds the concourse area with bays on three of its four sides. Shortly before the opening of Line 5 Eglinton, three more station entrances were opened on 16 November 2025: one just east of the Allen Road entry ramp, another just west of the Allen Road exit ramp, and one on the south side of Eglinton Avenue just west of Everden Road. The existing entrances were retained for direct access to the bus terminal for walk-in patrons not riding the subway. The Line 5 tunnel and platform passes under the Line 1 platforms. Above the Line 5 platform level, there is an underground concourse, constructed in conjunction with Line 5, divided in two sections by a gap where the Line 1 tracks cross. The main ticketing and concourse area at surface level is sheltered by an exposed concrete space frame supported by eight circular columns. The concrete ceiling is, in effect, a large slab and overhangs the entrance. With a glass
curtain wall, it appears to float. Inside, it is coffered throughout the station, with skylights in certain areas, allowing for increased penetration of natural light. The station's design makes use of sandblasted concrete and brick wall finishes extensively, distinguishing it from most stations on Line 1 and
Line 2 Bloor–Danforth, where tiles are predominant. As the north end of the station is in Allen Road's median, the Line 1 platform level is partly built at surface level. Designers took advantage of this and added windows at platform level. The northbound platform has regular windows, allowing for a view onto Allen Road, while windows on the opposite platform were frosted during construction of the aborted
Eglinton West line in 1994. This combination of window treatments allows transit riders to view cars speeding onto Allen Road's northbound expressway lanes, while blocking views of cars stuck in traffic approaching Eglinton Avenue, where the expresswayoriginally planned to continue south to downtownends. During July 2009, the TTC installed an $850,000
green roof over the northern end of the station to reduce maintenance costs, increase the lifespan by 40 to 50 years, reduce the heat island effect by lowering the temperature of the surrounding area by a few degrees, and to reduce runoff. The TTC had to repair the roof anyway, since it had been leaking since 2000. The plants atop the roof are low-maintenance
sedums.
Line 5 Eglinton The Line 5 additions were designed by NORR, following an architectural concept designed by architects
gh3* from Toronto and
Daoust Lestage Lizotte Stecker from Montreal. Two new entrances were built, one on the east side and one on the west side of Allen Road.
Super Signals was installed as part of a program to install artworks at major interchange stations along Line 5 Eglinton. File:New concourse at Cedarvale (formerly Eglinton West) Station.jpg|Cedarvale station new concourse level with
