Lodge, Ardenvohr, Gareloch Road, Rhu

This is a single-storey lodge, dated 1858, built in a Scots Jacobethan style. Originally a T-plan structure, it now features a modern, single-storey, flat-roofed addition to the west. The lodge is constructed from stugged, squared, and snecked sandstone with ashlar margins and dressings. It has bipartite, shoulder-arched windows with chamfered reveals, a base course, crowstepped gables, quoins, and an eaves cornice. Dormerheads are pedimented, and there are pedestalled, pedimented finials.

The north elevation, which faces the avenue, has a broad, advanced gable on the outer right, featuring a bipartite window with a raised star motif at the centre and Jacobethan strapwork to the gablehead. An apex stack is present. A recessed, gabled porch is situated in the re-entrant angle to the left, containing a round-arched door with bolection moulding and a blank escutcheon. A decorative cast-iron lamp bracket is also present. A blocked window is recessed to the left of the door, featuring a banner scroll above with a ball finial at the wallhead. A dormerhead is recessed to the left with three stars in the pediment and ball finials on the apex and sides.

The east elevation has an advanced, broad gable with a bipartite window and Jacobethan strapwork, topped with a finial. The porch is recessed to the right. The south elevation features a block to the outer right, with a wallhead stack at the centre. The eaves moulding rises as a pedestal, supporting a shield displaying the date 1858, framed by Y-shaped rainwater goods. A window is located to the left, and a slightly advanced gable to the left contains two symmetrically disposed windows. A flat-roofed extension is attached to the outer left, constructed of sandstone on the left side and rendered on its return. The windows throughout have a two-pane upper sash over a plate glass lower sash, with plate glass sash and case windows elsewhere. The roof is covered with grey slate and has lead flashings. There are tall, corniced sandstone apex stacks, one with a circular can on the east elevation and a similar wallhead stack on the south elevation. Moulded skewputts are also present. Decorative, painted blue cast-iron rainwater goods are visible, along with Y-shaped downpipes featuring sandstone gulleys and fleur-de-lis brackets on the south elevation. The interior was not inspected in 1992.

The entrance is marked by paired ashlar gatepiers, the ones on the right flanking a pedestrian gate. The left piers mark the north and south corners of the lodge, and have a base course, blank shield at centre, moulded surround, stacked, shouldered, conical cap with ball finial. Ornate cast-iron and wrought-iron two-leaf gates with Jacobethan decorative detailing provide access. A very low, semicircular coped boundary wall runs from the left gatepier to the outer left, sweeping around the corner to a higher rubble terrace wall to the south. It is accompanied by twisted cast-iron railings with fleur-de-lys heads and punctuated by squared and snecked dies, one of which is missing a ball finial. A boundary wall delineating the estate extends to the right of the right gatepier, constructed of rubble with ashlar, chamfered coping.
