One action the Revd Henry Wagner had taken before his death was the creation of a "building committee", consisting of other prominent members of the local clergy. The three Wagners offered this committee a choice between constructing a new church on a site chosen by the committee members - in which case only the original £3,000 set aside for the project would be granted, with the committee paying for any work beyond this - and accepting a site chosen by the Wagners, in which case the brothers would bear the full cost. The committee decided to allow the Wagners to choose the site themselves; accordingly, a position on the west side of Lewes Road, just north of the bottom of Elm Grove, was selected.
