Why it was refused

  1. The proposed development, by virtue of the bulk and siting of the rear dormer and its dominance on the roofslope combined with the design of the front dormer being viewed as a discordant feature within the street scene, would be detrimental to the visual amenity of the St Albans Conservation Area and the special interest of the Locally Listed building. The proposal is therefore considered to be unacceptable and to be contrary to policies 69(i), 72(i) (ii), 85 and 87 of the St Albans Local Plan Review 1994 and the provisions of the NPPF.

From the council's decision notice.
