Royal Horticultural Society Offices, Wisley Gardens

The Royal Horticultural Society Offices at Wisley Gardens were built in 1914 by Imrie and Angell in a picturesque Vernacular style. The building features brown brick plinths and is timber framed above with render infilling, along with some decorative brick and tile infilling and weatherboard cladding on the projecting bays. It has plain tiled roofs that are hipped and step down towards the ends.

The structure is two storeys high with attics, topped by a hipped roof that includes leaded casement dormers. There are several prominent chimney stacks: a square end stack on the left, decorative half-octagonal end stacks flanking a central square stack on the ridge plinth to the left of centre, another stack at the centre, and a fine front stack to the right with offsets and four round shafts under offset tops. One of the shafts features an arched panel.

On the first floor to the right, there are two casement windows, one on either side of the central stack. The ground floor has a mullioned and transomed window in a wooden frame. To the right of centre, there is a large, two-storey, hipped roof projecting bay with continuous mullioned and transomed glazing on both the first and ground floors, featuring diamond-paned upper lights that continue on the return fronts of the first floor. A similar hipped bay projects to the left.

Between the left-hand bay and the central gabled entrance bay, there are two first floor windows and one large, seven-light ground floor window. The entrance features a mullioned and transomed leaded casement on the first floor above an arched panelled door on the ground floor, which is set in a splay-sided brick surround under a five-step arched head. To the left end, there is a lower range with one six-light and one tall, narrow nine-light (3 x 3) window on the first floor, above two four-light ground floor windows.
