The Haymarket Theatre (Theatre Royal)

The Haymarket Theatre, also known as the Theatre Royal, is a Grade I listed building located in the City of Westminster. It was rebuilt between 1820 and 1821 by architect John Nash, during the same period as his development of Regent Street and Suffolk Street. The theatre was repositioned to enhance the vista along Charles II Street.

The building features a stucco exterior and a slate roof, showcasing Augustan neo-classical architecture. It stands two storeys high with a prominent attic storey, and is seven window bays wide. A giant pedimented portico supported by six Corinthian columns extends over the pavement, with entrance doorways on either side and an oculus above. The back wall of the portico includes five archivolt and key arched doorways, along with five architraved sash windows on the first floor. The modillion bracket cornice of the portico wraps around the sides of the building.

Above the portico, the tall sheer attic wall is adorned with a row of radial glazed oculi set in a panel below the frieze, which, along with the main cornice and blocking course, spans the width of the facade. The rear of the theatre facing Suffolk Street is also stuccoed and rises four storeys, featuring five windows. The ground floor is rusticated with a central rusticated pilaster and a corniced doorway. The first floor has arcaded windows that uniquely open directly onto the backstage area, with sunk panels beneath the sills. Above, a cornice leads to the attic storey, which includes elliptical windows situated between sunk panel pilasters.

The auditorium was redesigned in an elegant 'Louis XVI' style in 1904 by C. Stanley Peach.
