Why it was refused

  1. Reason 1 The siting of the proposed extension would be overbearing and result in unacceptable overshadowing of the living accommodation of No.19, namely the middle reception room and kitchen, causing demonstrable harm to the residential amenity of its occupiers.

From the council's decision notice.
