Last Sunday we went past Gunthwaite Hall, Barn (SE237065) and Spa (SE242061). I circulated some notes but I thought they be of interest to others so they are attached below. Nearby (SE246064) is Broad Oak which is a somewhat gnarled ancient oak tree that unfortunately you can only see over a wall but worth a detour. If I lead a walk in the area again I can also include the mill.
I think the area is well worth a visit and there are several routes that will take you past it.
