Great Portland Street Underground Station

Great Portland Street Underground Station is a Grade II listed underground station with shops, built around 1912 for the Metropolitan Line. The station features a cream faience tile facade and a slate mansard roof. It has an elliptical plan with entrances in slightly advanced pavilions at each cardinal point, surrounded by perimeter shops that lead to the booking hall and concourse. The design is in the Free Classical style and consists of two storeys.

The east and west pavilions have rusticated quoins and central semicircular arched entrances that are keystoned, flanked by square-headed keystoned openings. The first floor features two architraved windows alternating with three architraved panels. The north pavilion is four windows wide, with a central semicircular arched entrance in a rusticated surround, flanked by a semicircular arched opening and a blind recess on each side. The south pavilion is single-storey and finishes at the first-floor cornice, which runs continuously around the building.

Between the pavilions, there are shops and windows on the ground floor, with alternating casemented windows and panels on the first floor, similar to the east and west pavilions. In the north-east and north-west quadrants, shops are separated by engaged Doric columns. The station is topped with a cornice and blocking course. The concourse is illuminated from above and features square Doric piers, stone-faced with marble plinths, surrounding a booking office that was altered in the 1930s. The outer perimeter is flanked by pilasters that support the shop fronts. The original banded tilework is visible on the south wall and stairs leading down to the platforms, while the concourse floor has 1930s tiled geometric paving.
