The Braeside Inn was built by Gillies Bros. in 1888 to provide room and board for workers who needed seasonal accommodation. The Inn expanded in sections in response to Gillies Bros. increased workforce. The western section contained a medical clinic and a small library. Administrative staff from Gillies Bros. office often ate their noon meal in the large dining room located on the main floor. It was demolished by Gerald Desjardins in March 1979.
Constructed beginning in 1853, Daniel McLachlin moved his family to the stone house known as "The Hill" in 1859. In 1933, it was sold to R.M. Gemmel and known as Raithmuir. It was then sold to Colonel W.H Hadley, who sold it in 1946 to the Oblate Order of Mary Immaculate. In 1975, it was developed into a spiritual retreat centre known as the Galilee Community. It is now the Galilee Centre.
