Castle Oaks House (Woodlands) was built on a twenty five acre estate of good fertile land rolling down to the Shannon. The ground floor of the house itself consisted of a large entrance hall, two large reception rooms, ballroom, dining room, cloakroom & kitchen. The upstairs had seven bedrooms & three all purpose rooms.
The style adopted by the builders of CastleOaks has all the architectural characteristics that were predominant during the late Georgian period (1780 to 1830). The exact year of construction is uncertain, but is likely that Woodlands House was built in the closing years of the eighteenth century. The style used by Robert Adam a famous architect & designer of the latter Georgian period is evident throughout, particularly so on both sides of the main house which are semi-circular or oval. This was one of Adams trademarks, always preferring octagonal or circular rooms to the more conventional square or rectangular design. During the Georgian period the staircase was considered to be the most important internal feature of the great house, & at Castle Oaks the beautiful sweeping staircase leading from the charming entrance hall is most striking to the visitor's eye. It is synonymous with all the glamour & graciousness of the great country houses of Ireland & Britain.
