Ty Pab, including attached garden wall and gate

Ty Pab is a pair of houses (Nos 2 and 4 Church Street, Tremadog) constructed as a 2-storey, 3-window range built from large quarried stone blocks, roughly squared and laid in regular courses. The building is topped with a hipped slate roof on projecting eaves and features a stone chimney stack to the left of centre.

The front elevation presents a mixed fenestration reflecting earlier alterations. No 2's entrance is positioned right of centre with a recessed replacement door set within an original opening. To its left is a 6-pane hornless sash window inserted into what was formerly a doorway. At the right end sits an 8-pane sash window set into a large opening (likely once a shop window) beneath a timber lintel. At the left end (No 4), a 20-pane horned sash window has been inserted into a similar large former opening with timber lintel. The upper storey contains 6-pane hornless sash windows to the centre and right (noted in earlier surveys as Gothic in character) and a replacement window to the left. The right end of No 2 adjoins No 14 Market Square.

The left side wall of No 4 is articulated in four bays, with bays 2 and 4 featuring blind round-headed arches of dressed voussoirs, executed in imitation of the Market Hall. The entrance to No 4 is located on the right side of the second bay and retains an original opening containing a replacement split boarded door. Bays 1 and 3 contain 4-pane sash windows in the lower storey set beneath slate lintels, with replacement windows in the upper storey occupying earlier openings. At the left end, a 1-storey rubble stone projection with slate roof has been added, featuring a replacement half-glazed boarded door and replacement window to its left.

Attached to the left end of No 4 is a short garden wall of coursed rubble stone with coping. It features a pointed doorway with dressed voussoirs and a wrought iron gate with railings forming ogee arches, incorporating a quatrefoil and trefoils within the main arch. An identical gate exists at Plas Tan yr Allt.

Internally, the entrance leads to a hall with an open-well staircase featuring a turned newel and plain balusters. The stairwell and one of the upper-storey rooms retain a plaster vault.
