Yes, that's the same estate. There's Larkfield Avenue, Grove, Gardens and Park - here on Google Maps: 53.31889,-6.289566
Incidentally, where did you get the builder's name? (And does 'for Rathmines Public Utility Society mean that he was working on commission for the Corporation?) Can you find anything about a builder called Hughes who built the nearby houses in Clareville Road, also in the 1930s?
