Royal Institution of Chartered Surveyors the Royal Institution of Chartered Surveyors

The Royal Institution of Chartered Surveyors is an institution headquarters built between 1896 and 1898 by Alfred Waterhouse, with later additions by his son Paul. The building features warm red brick with extensive stone dressings and slate roofs. It showcases Waterhouse's unique interpretation of Jacobean architecture combined with elements of Flemish Renaissance and Gothic verticality.

The structure consists of three tall storeys, a basement, and an attic, with the rear hall range facing Little George Street and Parliament Square comprising two tall storeys and an attic. The entrance front is symmetrical and five windows wide, featuring a central porch with granite columns and a segmental cornice. The ground floor windows are mullioned and transomed, framed by panelled pilasters. The first floor boasts very tall mullioned windows with two transoms, while the second floor has triple light windows with strapwork panelled aprons. A stone balcony is present on the first floor, and a prominent crowning cornice is topped by an elaborately designed pilastered "Venetian" dormer.

The east gable end is decorated with stone bandings and topped by an ornate chimney stack. The hall range is connected by two bays of cross mullioned windows with gable attics, along with a recessed bay featuring lofty mullioned-transomed stairlights. The hall itself is highlighted by three tall semicircular arched windows at the southeast corner.
