The original post was back in 2008 maybe Kopperknob has found what they wanted by now? I hope they come and post to let us know.
AnnesleyAl....
Are you referring to Ash farm in Sutton in Ashfield which was where the site of the current Ashfield Comprehensive school is ?
But wouldn't that be classed as Kirkby in Ashfield?
duckweed....... are you thinking of the windmill that was at Sutton Junction and now demolished?
are maybe the one on Prospect Place, High Pavement and now listed?..... I thought you just might be right as there was property mid to late 1800's on High Pavement called "Ashfield House"..... but I think like a good many they no longer exist.
Re Ashfield House, High Pavement, Sutton in Ashfield
1881 - RG11/3315/26/page5 ..... Morgan F Hamerton, Physician & Surgeon, Ashfield House, Sutton In Ashfield
1891 - RG12/2652/22/page 4 - Robert Nesbitt, Medical Practitioner, High Pavement, Sutton In Ashfield
1901 - RG13/3137/17/25 - Robert Nesbitt, Physician & Surgeon ,Ashfield House, High Pavement
Robert Nesbitt, Medical Practitioner is still in Sutton on Ashfield in 1911, the house isn't named only given as High Pavement.
However, I think you are both wrong 
The actual name of
"Ashfield Farm" only appears on the census after 1901 but tracing the family back to 1881 and although there is variation of address, it appears they are always in the same place.
Which makes the Ashfield Farm/ House here....
