4, Emlyn Square

No. 4 Emlyn Square is a house built in 1847 for the Great Western Railway Company as part of a village designed by Isambard Kingdom Brunel to accommodate the workforce for the new railway works. The village layout, based on Brunel's early drawings from 1840, features a grid pattern with 12 terraces in six blocks on either side of the High Street, now known as Emlyn Square. Construction began in 1842, and by 1855, most buildings were completed, although financial difficulties delayed the project.

The house is constructed from ashlar limestone and has a slate roof. It is two stories high with three bays. The central entrance features a four-panelled door that is half-glazed. The ground floor has four-pane sash windows set within chamfered ashlar surrounds, complete with label moulding. Above the door, there are chamfered slit windows. This house is similar in design to No. 2 Emlyn Square. The village is recognized as one of Britain's best-preserved and architecturally ambitious railway settlements.
