Tigh-Na-Mara, 152 Clyde Street East, Helensburgh

Tigh-Na-Mara is a two-storey villa with a lower two-storey wing to the east and a single-storey service wing adjoining, constructed in 1905 with major additions and alterations to an earlier building, designed by William Leiper. The villa is largely harled and painted white, with cream sandstone ashlar dressings. Some windows have ashlar margins, while others are ashlar mullioned and transomed. Overhanging brackets support the eaves, which are swept on the principal block.

The north (entrance) elevation features a slightly advanced centre bay with an elaborate doorpiece displaying Moorish decorative details. The round-arched doorway is set within a square panel featuring rose and thistle carvings to the spandrels and an inscription above reading "FIDES PRAESTANTIOR AVRO 1905." Above the doorway is a panel with twin round-arched lights, roll-moulded surrounds, and a pierced stone balcony to a transomed window at the first floor. Mullioned and transomed windows with lead-pane glazing are on the left at ground and first floor, and a mullioned and transomed window is on the outer right at ground level. A canted ashlar window with lead-pane glazing and a flat lead roof is on the return to the left.

The recessed two-storey wing to the left (east) has a round-arched doorway off-centre to the right with deeply chamfered reveals and a modern glazed door. A small bipartite window is to the right, and a tripartite window is to the left, set in a round-arched panel within a slightly advanced squared bay. There are three asymmetrically disposed windows at the first floor. A curved return leads to the east.

The west elevation has a bipartite window to the left at ground level and a doorway to the right, with a modern conservatory abutting. Two windows are at the first floor.

The south (rear) elevation’s main block has a broad, advanced, canted bay recessed to semi-circular at the first floor, topped with a conical roof. Two canted windows are to the left, featuring mullioned and transomed windows. A pair of bipartite windows are above at the first floor.

The wing to the right has a two-storey bow window in a re-entrant angle, alongside a semi-circular stair turret with a conical roof and a window to the right at the ground floor, as well as a bipartite window at the first floor above. A single-storey wing adjoins at the southeast angle.

The windows are mostly plate glass and small-pane sash and case, with some lead-pane glazing. The roof is rosemary tiled, with sandstone corniced harled stacks and some original rainwater goods.

The interior features wainscot to the hall, a timber beamed ceiling, a double round-arched screen to the stair and vestibule, a timber stair and balustrade, a fine inglenook to the hall, and wainscot to the principal rooms. There are some original chimneypieces and geometric plasterwork ceilings.
