This sub-series contains records related to the renovation and maintenance of the main church building and property located at the corner of Sherbrooke and Simpson before the fire in 1987. It also contains correspondance and internal reports related to a move proposed in 1983 that never occurred, as well as correspondence and legal documents related to dealings with the neighbouring Port Royal apartments from the 1960s and early 1970s. These include agreements and communication related to maintenance and use of a shared lane between the two properties, as well as the sale of a piece of the Church's lot to Port Royal in the early 1970s.
The majority of the series is comprised of architectural and zoning plans, as well as meeting minutes and internal Church reports, regarding the renovation and maintenance of the main church building. The architectural plans were drawn up by the firm Chadwick Pope & Edge through the 1960’s and early 1970’s. The zoning plans are from 1912, 1954, 1962 and 1972, presenting a good representation of how the lot changed over time. The reports and meeting minutes were generated by the Building Committee and Special Committee of Acoustics, including a survey of the congregation on space needs. There are also a 29 black and white photographs. 26 of these are of the interior of the church, used in a property study and focusing mostly on structural defects. The 3 remaining photographs are external shots of the church building from 1970. Also included is correspondence from la Musée des beaux arts related to the building’s stained glass windows.
