Thames House

Thames House is a late 17th century house located on the south side of High Street in Wallingford. It features a flint base leading to a plinth and is constructed of red brick in Flemish bond. The roof is covered with old plain tiles and has brick stacks at both the left and right rear. The building is two storeys tall with an attic and has a three-window range.

Access is via stone steps leading to a four-panel part-glazed door, which is framed by a painted wood architrave, an overlight, and a flat hood supported by shaped brackets at the center. All windows, except for one on the ground floor right, are 12-pane unhorned sashes with thick glazing bars; the exception features thin glazing bars. There is a flat brick band between the ground and first floors, and a painted moulded wood cornice at the eaves. The house also has two gabled full dormers with horizontal sliding sashes. The left side of the building has irregular fenestration. The interior has not been inspected.
