Kerfoot's, Porthmadog, originally Roberts & Co, is said to have been established in 1874 (date on building), probably as a chandlers. The building is a 3-storey 3-bay shop with a whitened rendered front, rusticated quoins painted green, and a slate roof on a deep moulded corbel table.

The shop front is brought forward, and is framed by fluted pilasters and a deep fascia incorporating awnings above the windows. The central recessed entrance has double glazed doors with faceted panels to the base, and overlight, with round-headed windows to the returns of the shop front. The ground floor has unusually high ceilings, and is open, with the upper floors carried on cast iron posts. The dominant interior feature is the central, full-height, self-supporting geometric stair with turned balusters and newels, and moulded tread ends. The ground floor retains some moulded ceiling cornices.

The shop front was renewed in the late 20th century.
