Why it was refused

  1. The development, by virtue of its large depth at the first floor against the common boundary has a significant overbearing and overshadowing impact on the property at No. 17 Rowan Close, and would lead to the loss of light to a habitable room. This would have an unacceptable impact on the amenity of that property. As such, the development is contrary to Policy CW2 of the Caerphilly County Borough Local Development Plan up to 2021.

From the council's decision notice.
