Hello Sueky
The map on the Bold Parish Council website is actually modern - it's dated 2006. The Royal Mail has a modern address for the property as:
Home Farm, Hall Lane, Bold, St Helens, WA9 4SJ
suggesting it's still there. I also note on the Bold Parish Council has a list of 'buildings of special architectural and historic interest' includes Farm House at former Bold Hall Estate, Hall Lane and Farm Buildings, formerly the stables, at Bold Hall.
Also, the St Helen's Council website has a planning application:
http://212.248.225.150:8080/portal/servlets/ApplicationSearchServlet?PKID=13875from 2002 for the conversion of the farmhouse at Home Farm into two flats and the stables and other outbuildings into houses. If you contact St Helen's Council they should be able to show you the plans that were submitted, which will probably include a plan showing the internal layout and elevations as existing at the time the application was made.
If you want to see an old map, try
www.old-maps.co.uk and enter the co-ordinates 354600 / 391800 - this has a number of maps of the area ranging from 1849 to 1927.
Going back to
www.imagesofengland.org.uk if you do a search for Bold Old Hall there are two listed buildings - the gateposts and a bridge of the original building - but if you look in the background of the picture of the gateposts there are clearly some farm buildings - possibly part of Home Farm?
