Description
102 Heol Maengwyn is a row of five almshouses built in the mid-19th century. The building features a symmetrical two-storey front made of coursed rubble, topped with a hipped slate roof and wide boarded eaves. There are chimney stacks on the rear roof pitches. Small gables are present above the first-floor windows at both ends and the center, which flank advanced and gabled bays at Nos 96 and 100. Most of the gables retain pendants and finials, and all have undulating bargeboards. The windows are small pane, two-light casements with Tudor labels, triangular heads at the small gables, and diamond panes at the apex; these windows extend through the eaves. No 96 features rose pattern bosses flanking its windows, while No 94 has a boarded door, with the rest being half-glazed. The rear has four gables, with the one at No 94 being broader; the chimney stacks here are partially rendered. Nos 94 and 96 still have sliding sash windows, and there is a rubble lean-to on the left.
