That is unbelievable!
Presumably the pictured wall is coming down too?!
Remembering the initial decision:
"The proposed development, by reason of the demolition of an existing habitable house, which contributes positively to the character of this residential conservation area, would be contrary to the Z2 objective in the Dublin City Development Plan. Moreover the proposal does not accord with principles of sustainable development and policies to discourage the demolition of habitable houses (Res 5). The proposal would render it difficult to resist similar development, which would cumulatively undermine the character and legibility of the Conservation Area irrevocably. It is therefore considered that the existing dwelling should be retained in accordance with policies H13 and H27 of the Dublin City Development Plan."
What a disgrace.
Good luck with your call publicrealm - impressive how involved you'd become in this, to the point of hauling a stepladder to the site perhaps.....?
Regarding the house itself, as alluded to earlier, it would appear to have been substantially altered already in spite of its relatively uniform appearance. All of this lower principal elevation would seem to be a late 1950s extension (with slates also added):
...wrapping round the side to the rear and rising to two storeys:
Take all of this away, including the small flat-roof extension in the middle above and the imitation boiler chimney to the front, and an almost entirely different (more conventional) c.1930 house emerges.
Not that what appear to be later additions didn't offer it an added charm - alas none of this matters anymore
