Its centrepiece, added by Edward Blore in around 1837, consists of an arched stone entrance flanked by pilasters, above which a clock tower rises from the first-floor level. The tower features twinned arrow-slit windows and clock faces with stone surrounds, and is topped by a bell chamber and ogee cupola with finials. In addition to the centrepiece, the east face has four bays which are set forward and have shaped gables topped with finials. The north and south ends of this east building also have shaped gables. The north and south sides of the quadrangle have large arched carriage openings beneath shaped gables; the keystones are carved with horse's heads. The walls within the carriageway opening are decorated with bands of blue brick. The east, north and south faces are all finished with an openwork brick parapet with a stone coping. The west building has twelve arched openings accessed from the courtyard. The main storeys of the quadrangle mainly have three-light, stone-dressed mullion windows, with two-light windows at the attic level. All the roofs have tall octagonal chimneys and feature decorative ridge tiles. The interior of the stables block was rebuilt during the building's conversion to its present use of laboratories and offices. The Apple House, a small red-brick building to the west of the stables quadrangle, also dates from around 1636, and can be seen in a painting of Crewe Hall from around 1710. Originally a dovecote, it is used as a storehouse. Built on an octagonal plan with two storeys, it has two oval windows with stone surrounds. The lower entrance has a stone semicircular arch; a second doorway is located at first-floor height. The pyramidal tiled roof is topped by a glazed lantern with a lead cap. The building is listed at grade II. The park has two gate lodges; both are listed at grade II. The northern lodge at Slaughter Hill is by Blore and dates from 1847. In red brick with darker-brick diapering, stone dressings and a slate roof, it has a T-shaped plan with a single storey, and is Jacobean in style. It features two shaped gables, each decorated with a panel carved with Crewe Estate emblems, and a hexagonal central bay with a pyramidal roof which forms a porch. The Elizabethan-style Weston or Golden Gates Lodge to the south of the house dates from before 1865 and is attributed to William Eden Nesfield, although it is not typical of his style.
