There are three other things in your photograph that may indicate that the house is Kentish.
The chestnut fencing in the foreground was very common in Kent up until about thirty years ago.
The chimney stacks are very Kentish and are common in the Cranbrook area. The two taller stacks have a suggestion of 'Quaker style' at their tops, raised brick pattern. The one behind looks to be a definite 'Quaker chimney' very wide at the top and if it could be seen totally would, more than likely, reduce in width just below what can be seen. A legacy from the Flemish cloth makers who settled in the Cranbrook area, I think in the 17th. century.
Also, in the background there looks to be an orchard, by their shape, apple trees.
Not conclusive but adds to the possibility.
