The current church building was built between 1872 and 1874 replacing the original church building erected in 1828 and modified in 1854. Built in a Neo-Gothic style (also known as Gothic Revival) the architectural plan includes features such as lancet windows, modified butresses and tracery. The original structure was built by stone masons who had been brought from Scotland to build the Rideau Canal. Standing on the corner of Wellington at Kent street for over 180 years, St. Andrew's is now one of the only non-governmental buildings along Wellington Street.
The orientation of the pews inside the church is typical to churches of the reformed tradition that emphasize the spoken Word of God (readings, sermons and prayers) and the role of the teacher (minister) as the leader of worship. The high pulpit, which is undoubtedly the central architectural focus of the interior, emphasizes this tradition. As you make your way through the sanctuary, you may notice small brass plates on some of the pews. These plaques name former notable members of the congregation, many of whom held significant office in the government of Canada through the years.
St. Andrew's Hall below the sanctuary in the basement is a multi-functional space used for gatherings, receptions, church school, bazaars, etc. Modern facilities and office spaces beyond the south sanctuary doors in the adjoining office tower are used by church staff, church groups and visitors. The architectural connection between the church and the office building (built during the reconstruction project in the 1970's and 80's) is an outward symbol of the vision of outreach of the Church to those living and working in the city core.
