The old hall footprint is well established as a result of the ground plan produced by George Fowler Jones architectural parctice in 1885, this is still in existence and held I believe at Temple Newsam. I obtained a digital copy of the reference photograph some years ago and have used it extensively to assist in discovering how the parts of the hall were aligned on the ground. However with the recent discovery of the photographs taken by Jones in the latter part of the nineteenth century; held at the National Media Museum, Bradford, it became clear that the lawns had extensive flower beds. Moreover the plan shows drainage lines and the position of the fountain and the river Crow which runs across the lawns in a stone culvert. We decided therefore to undertake a geophysical analysis of the ground to determine if any of the earlier features could be discovered.
