SNN107912 - Ground penetrating radar survey, Chester Farm, Irchester, Northamptonshire

The purpose of the ground penetrating radar survey was to investigate the possibility of unknown underground features (cellars, vaults) around Chester Farm that may prove a hazard to proposed stabilisation works. Significant features were found on the north and west sides of the house. Previous measured survey had mapped a pair of cellars on the north west side of the house; these appear to have been located successfully at an approx depth of 2.5m to 5m below the surface. A possible second feature was on the north east side of the house between 1m - 7.1m deep. Two features were located on the west of the house. A possible infilled excavation in the south west was imaged at between c.7.7m - 9.7m below the surface. North east of the house was an unknown subsurface feature, possibly another backfilled excavation.
