No. 15, Broadhalgh Avenue

No. 15 Broadhalgh Avenue is a house dating from 1907 to 1909, designed by Parker and Unwin for Mrs Ashworth. The house is constructed with roughcast render, ashlar stone dressings, and a graduated stone slate roof. It has a rectangular plan, linked by a covered walkway to a boiler room wing and a billiard room, one positioned to the left and the other to the right. Each of these three blocks is one storey high with attic rooms. The design is strongly influenced by the style of C.F. Voysey, characterised by large hipped roofs. The house features an ashlar plinth, battered angled corner buttresses, and overhanging eaves. A central doorway has a leaded glass panel and copper ironmongery, with four small windows situated to the left. Timber posts support the eaves, creating a walkway. A long dormer window is also present. The wing to the left has six bays, each containing three or four-light recessed flat-faced stone mullion windows and dormer windows that project through the eaves. The billiard room wing comprises two bays and is partially obscured at the front by a flat-roofed garage. The rear elevation features two square bay windows, with the main roof sweeping downwards to cover them. Between these bays are double doors, along with a three-light window and a single-light window on either side, plus a nine-light dormer window. The windows have leaded panes, and the original fittings remain on the doors. Tall chimney stacks are accentuated by wide cornices. A pergola and double gates, featuring a hipped roof supported by massive piers, enclose the front courtyard.

The interior is dominated by a full-height room, with the deep plan illuminated by the dormer windows. A floor was inserted in the 1930s, but most of the original fittings remain, including timberwork, light fittings, panelling, doors, and fitted furniture such as a wardrobe and desk. A large inglenook fireplace is also present. The design was considered by Parker to exemplify "the application of those qualities and principles of architecture for which I have been contending," as noted in "The Craftsman" (1910).
