In accordance with Section 81 of the Planning & Development Act, a development plan shall include an objective to preserve the character of a place, area, group of structures or townscape, taking account of building lines and heights, that a) is of special architectural, historical, archaeological, artistic, cultural, scientific, social or technical interest or value, or b) contributes to the appreciation of protected structures, if the Planning Authority is of the opinion that its inclusion is necessary for the preservation of the character of the place, area, group of structures or townscape concerned and any such place, area, group of structures or townscape shall be known as an “Architectural Conservation Area”. ACAs contribute to the revitalisation of the fabric of towns, villages and rural areas by supporting their aesthetic value, giving them a distinctive identity, and thus make a positive contribution to local economies and tourist potential. The designation of an ACA does not prejudice innovative and contemporary design; on the contrary, in principle, design of a contemporary and minimalist style will be facilitated within ACAs provided it does not detract from the character of the area.
