The original M&amp;LR single-storey offices facing Hunt's Bank Approach were built in the Italianate style in sandstone ashlar with slate roofs in 1844. They were later enlarged and given a second storey. William Dawes built the station's larger extension for the L&amp;YR in 1909. It is at right-angles to the north end of the old station giving the enlarged station an L-shaped plan. Facing Victoria Station Approach, its façade is in the Edwardian neo-Baroque style, four storeys high and 31 bays to the rounded corner at the south-east end. The ground floor windows have rounded heads and those on the floors above are square. The ornate glass and iron canopy along the façade displays the names of destinations that the station served in Art Nouveau lettering. The canopy was damaged by the Provisional IRA's 1996 bomb placed in a street adjacent to the Arndale Centre and was restored four years later.
