Hafodneddyn

Hafodneddyn is a late Georgian style house of two storeys comprising a central range with north and south cross wings. The walls are whitened rendered brick, with hipped slate roofs to the principal elevations and gabled roofs to the service elevation. Rendered and brick chimney stacks serve the building.

The south-facing front is asymmetrical with seven bays. The main entrance is located in the south cross wing, set within an advanced bay that was remodelled in the 1950s. The bays to the left of centre feature a lower eaves line and contain service rooms, while the principal rooms occupy the right side. The central doorway is framed by pilasters and a pediment, with panelled reveals and double glazed doors. The window above has an architrave and 12-pane sash window. To the right of centre stands a 9-pane upper-storey window, followed by a projecting pedimented bay with a 9-pane horned sash window in the upper storey above French doors. The right end bay contains only an upper-storey 9-pane sash window. To the left of centre is a 12-pane sash window in the lower storey and a 9-pane window above, then a blind projecting bay with pediment (narrower than the corresponding bay on the right), while the left end bay has 12-pane and 9-pane sash windows in lower and upper storeys respectively.

The east garden front shows the 3-bay central range under a separate hipped roof on bracketed eaves, representing the original house, with the higher cross wings added in the 1850s and brought well forward. In the central range, lower-storey openings have plain architraves while upper-storey openings have keyed architraves. A central full-height canted bay window has 12-pane horned sash windows in the upper storey and hornless sash windows in the lower storey with central French doors. The outer bays have 12-pane horned sash windows, except the lower left which is a hornless sash. The cross wings feature plat bands, hipped canted bays in the lower storey with French doors, and tripartite 2-pane upper-storey sash windows under corbelled cornices.

The north elevation of the north cross wing has a plat band to the left side. On the left are French doors in the lower storey and two 4-pane sash windows in the upper storey. To the right of centre is a 16-pane sash window in the lower storey with a replaced door to its left, and in the upper storey a 12-pane hornless sash window with a similar but smaller window to its right.

The courtyard elevation on the west side comprises the gabled north cross wing brought forward, two gables in the central range, and the south cross wing projecting further forward under a hipped roof. The south wing has a half-lit doorway to the left in the lower storey, sash windows and a replaced attic dormer window. A flat-roof projection is added to its left side. To the left of this is a doorway in an added small gabled porch between the two gables in the central range. The right-hand gable also has a boarded attic opening. The north wing has a half-lit door in its side wall. Windows throughout are small-pane sashes.

The entrance opens into a long hall with principal rooms on the right and service rooms on the left. Inside the entrance are two bays of elliptical arches; the second on the right opens to the drawing room in the south cross wing. This room has panelled reveals and an internal doorcase with scrolled pediment, classical cornices and a neo-classical fireplace surround. The second room on the right, in the earlier central range, is plainer but has a similar fireplace. Near the end of the hall is a straight stair with moulded cast iron balusters and wreathed wooden hand rail. The room at the end of the hall, now a billiard room, is in the north cross wing and has a marble fireplace surround. The principal rooms retain panelled shutters.
