Maurice Sandes was in possession of this property at the time of Griffith's Valuation, when it was valued at £60. It is labelled as Oakpark on the 1st edition Ordnance Survey Map. In 1837 Lewis recorded Oakpark as the seat of John Bateman. Bary writes that, Killeen, the original house at this site, was a late seventeenth century house. It was followed by Oakpark, built by John Bateman in the 1820s. This is the house mentioned by Wilson in 1786 as the seat of Rowland Bateman. Maurice Sandes purchased the estate in the late 1840s and built the later Oakpark House c.1857. In 1906 this house was owned by Falkiner Sandes and valued at £112. The house was sold in 1922 and is now used as offices.
