For about 700 years Cadder Church served a large rural area, the old parish stretching from Bearsden to Stepps. The building of the main Edinburgh to Glasgow railway in 1842 marked the start of the transformation. The Rev. J.B.A. Watt was called to minister in Cadder in 1882. Among many vigorous initiatives, the Kirk Session minutes of 6 January 1885 record: "The Moderator is authorized to procure further information as to a Hall at Bishopbridge (sic) and when convenient present a report to the Kirk Session." Mr Watt must have continued his enquiries as the village of Bishopbriggs grew, but it is not until 18 January 1896 there is sudden and decisive action: "The Moderator gave a detailed statement of what had been done in connection with the hall which it is proposed to erect in Bishopbriggs. The most interesting and important part of this intelligence was the prompt and liberal offer from the Lord of the Manor of a site at a nominal rate, and a donation of fity pounds towards teh building fund." And the minute goes on to give the full text of the letter from the Victoria Barracks in Windsor of Archibald Stirling Esq. of Keir and Cawder. By 30 April 1896 the Kirk Session had before them "the Estimates for the building of the Church Hall". These totalled £939.10.7 "It was agreed to begin building operations forthwith and instructions were given accordingly". The minutes of 12 january 1897 tell us that "the Church Hall at Bishopbriggs ... was declared to be now nearly finished ... opening services to be held early in February". When the bills were all gathered in the total cost was found (in September 1897) to be £1598.0.9 Receipts had been £1435 so the Kirk Session was responsible for the bank overdrafts of £163. "A long felt want had been supplied in the chief centre of population in the Parish, and ... the Church of Scotland in thsi district is now fully equippped for the work to which she has been called." So the South Hall was built and with the superb extension of the early 1970s continues to serve the needs of church and community.
