The house is planned around a central hallway with principal rooms in the front block and service rooms and servants' quarters to the rear. The entrance leads into a small vestibule with cloakroom off to the left, both with a mosaic patterned floor. The hallway has a corbelled picture rail, and timbered arch over the first step of the stairs; dog-leg staircase with tapering splat balusters, some pierced with shaped motifs, and square newel posts with projecting caps. The ground floor rooms retain picture rails, the sitting room rail corbelled, and the dining room and drawing room have the original fire surrounds. The dining room fire has a wooden surround with tiled inset, the widely projecting moulded cornice on tapering Ionic columns with fluting to the heads, an oval mirror set above the corbelled mantle. The drawing room has a similarly detailed surround but with plain tapering columns. Some of the bedrooms retain original cast-iron fireplaces, some with floriate decoration. The bathroom retains original fittings and tiling and the pantry, some of the original glazed cupboards. Many of the panelled doors are original and retain their Art Nouveau style floriate handles.

Arts and Crafts style house, 2-storey with attics, with characteristic asymmetrical form. Large grit rendering with smooth-render in the gable apexes and roughly dressed stone plinths to the bay windows and entrance wall; sandstone dressings. Roof of small green slates and red clay ridge tiles, with broadly projecting eaves with ornate scrolled iron brackets. Tall rectangular stacks, grit rendered and with brick 'corbels' to the capping, stacks are to the right (N) of each gabled bay to the front of the house with a single ridge stack to the servants' quarters to the rear; the front stacks have gabled steps at the base of the front faces. The house is planned with principal rooms to front, the entrance recessed between 2 gabled bays; half-glazed double doors with Art Nouveau-style leaded glass and floriate brackets to right, tripartite window of 3 leaded lights and chamfered mullions to left. Set in the roof above the entrance is a flat-roofed dormer of 4 small-paned lights; other windows are small-paned horned sashes. The right gabled bay has a ground floor canted bay window with shaped leaded roof up to a canted oriel above. The left gabled bay has a ground floor canted bay window, 1st floor tripartite window and a circular leaded 1st floor light to the left. The left return elevation has a tripartite window to the right and a gabled bay to the left, with similarly detailed windows to those of the right gabled bay of the front elevation; the rear elevation of the gabled bay has a large stair window of 3 rows of 4 leaded lights. The right return is abutted by a flat roofed garage block of 2 garages, each with large boarded doors; ground floor has a single window to the left and canted bay window to the right, 1st floor with tripartite window to the left and paired window to the right. To the rear of the main house is a gabled wing with entrance in a gabled porch to the N side.
