The shape of the building was cut out at the Raheny end of the estate, with a curtilage provided, in 1885, and building commenced shortly thereafter, and the new All Saints' Church was completed around October 1889. The Service of Dedication of the church was planned for All Saints' Day 1889 (1 November) but due to a death in the Guinness family was delayed to 16 December 1889. Full consecration could not take place, as the freehold of the land was not available at the time, being held by the Howth Estate. Lord Ardilaun committed to maintaining the building on two conditions, firstly that the rites of the church be standard, and second that both the new and old (St. Assam's) churches be well-maintained. A tree-lined avenue was laid out between the church and the main body of the St Anne's Estate.
