The Incorporated Church Building Society, established in 1818, was initially unable to subsidize secular-use buildings from the general fund. However, in 1858, it established the mission building fund and began to construct hamlet chapels, school churches, mission halls, and mission rooms. In the early years, there were some examples of dual-purpose buildings without a strict distinction between sacred and secular spaces, but a type of building with a church on the upper floor and secular rooms on the lower floor emerged. However, the distinction between sacred and secular spaces was insufficient, and a stage for secular use had not yet emerged.
