The cost of its erection was provided out of a bequest by a Miss Shannon, a wealthy lady of Belfast, left by her to build a number of churches in or near Dublin.

On 3 January 1868, the Daily Express issued the following account: The consecration of the church was postponed until Sunday 8 July 1868 as the building had yet to be completed.

The existing church building form expresses clearly the several alterations and extensions to the original, resulting in several volumes that are interconnected, but with each retaining their own identity.

A robing room and parish office was created in the space vacated by the organ and a toilet installed at the back of the church.

The building remained in its original form until 1968 when an extension to its west side, to provide for a caretaker's apartment as well as additional meeting rooms and facilities, was added.

The sod was turned to begin construction work on a new parish centre within the grounds of the church on Sunday 19 March 2006.

A house left to the parish by the late Odette Gatenby was sold and the proceeds added to the restoration fund.

During that time the congregation worshipped in the parish centre and over Christmas and New Year had a number of joint services with their neighbours in Christ Church, Dun Laoghaire.

However, based on the reports from our consultants, and detailed inspections, our Design Team, led by fellow parishioner and conservation architect, Bryan Roe of Scott Tallon Walker, Architects, proceeded to obtain planning permission for the works and to prepare tender documentation which was then issued to several suitable building contractors for pricing.

With the appointment of Dave Stanley (who formerly assisted St Paul's in Kisiizi Hospital) as our Project Manager, work started in July 2012.

When safe access was put in place at the commencement of the contract, an inspection of the listed risk items revealed the need for several significant additional tasks, including woodworm treatment of the attic timbers and the removal of three further stained glass windows.

These items necessitated four Section 5 Planning Applications being submitted to the Local Authority, as the church is a Protected Structure.

Spire: Replaced top stone and repaired/repainted the cross; removed the levelling shims and applied repair mortar in the damaged joint around the entire perimeter; undertook spot repairs to spire stone work, including pointing; replaced the lightning conductor.

Decoration: Painted all surfaces except exposed stone and the organ, including ceilings, timber arches, pews, cupboards, sanctuary timber panels, new plastered areas; painted external louvres in tower and dormer vents and all ironware, including downpipes and main gates; laid new carpets only in essential areas – back and front of church, side chapel, Vestry, stairs to balcony, main corridor on balcony; laid new floor covering in toilets.

In 2015, 2016 and 2017 the choir undertook a tour to the Diocese of Derry and Raphoe and sing every summer in St Patrick's Cathedral, Dublin.

A great number of new stops were added (mostly to the Pedal, which is now very developed) and a new console was built retaining the original keyboards.
