Smithkline Beecham House Including Midland Bank

This building is a factory, later adapted for use as company headquarters and offices, and incorporating a bank. The eastern wing was constructed in 1936 by G A Warren, while the majority of the building, dating from 1937 to 1942, was designed by Wallis, Gilbert and Partners for Simmonds Aerocessories. Subsequent alterations were undertaken between 1955 and 1960 by R Gallanaugh for Beechams, and further modifications occurred later. The exterior is built of pale brick laid in Flemish bond, with concrete and ashlar detailing to the plinth, sills, lintels, window jambs, architraves, fins to the tower and flanking blocks, the upper storey of the tower, and the parapets. The roofs are flat concrete.

The main structure comprises an 11-storey central tower, set forward and overlapping the front corners, flanked by lower 3-storey blocks. Long, two-storey side wings with a basement terminate in circular entrance towers (slightly taller than the wings) and return at the rear.

The main entrance to the tower has late 20th-century glazing, fascia, and balconied windows above, linked by a deep band connecting the flanking blocks. The tower features a three-light window with original metal glazing bars, extending to the eighth floor. The ninth floor is adorned with a figure of a pilot with an eagle on their shoulder, standing on a pedestal, and an indented parapet. The returns of the tower have similar nine-light windows, with nine windows to the top floor, some with replacement glazing. The rear elevation has plainer three-light windows, accompanied by flanking narrow windows on each floor, and incorporates a chimney. The blocks flanking the tower each have a full-height five-light window to the front, five plainer windows to the rear, and nine to the returns, retaining original glazing bars except to the lower floors at the rear. The side wings feature near-continuous windows separated by wide jambs, with only the basement windows retaining original glazing bars. Curved corners are present at the junctions with the end entrance towers. These towers have steps leading to a double door with bowed columns and a hood, with a window above, flanked by fins and tall, narrow windows. Each wing return has a later entrance at the east end. Later wing extensions and additions are visible to the rear of the wings and to the tower.

The interior of the tower retains an original staircase on the right-hand side, with a marbled lobby and a keyed round archway on the second floor. A marbled lift lobby is present on the left of the first floor, and within the reception area. The remainder of the interior has been considerably altered.
