Tremadog was a town created by William Madocks (1773-1828) in the first decade of the C19 on reclaimed land known as Traeth Mawr, the estuary of Afon Glaslyn. It was originally intended to be a post town on a direct road between London and Dublin, via Porthdinllaen on the Lleyn peninsula, a project that in due course lost out to the Holyhead Road. Tremadog was laid out around a market square, with market hall, coaching inn, houses and shops, with a church and chapel just outside the centre. Building of this small planned development, as well as a separate woollen manufactory, began c1805 and was largely completed by the time Richard Colt Hoare described it in 1810. No 11 Market Square was part of this first phase of development.


A 2-storey double-fronted house slightly altered when converted to 2 premises. Of roughly coursed and squared quarried stone with stone lintels, renewed slate roof on boarded projecting eaves, with stone end stacks. The central entrance has a replacement door with large glazed panel. On the L side are 2-pane horned sash windows, shorter in the upper storey. On the R side is a shop front inserted in place of an original window, with recessed glazed door and small-pane window, and 4-pane sash window in the upper storey.


Not inspected.
