Rock Community Church is located in Woodbridge, Ontario, directly north of Toronto. Several years ago, the congregation bought a large, wooded property and used an existing residence and outbuildings for their needs while funding was acquired and design was developed for a permanent facility. Designed to incorporate a detailed list of user requirements, the new building was ready for occupancy in October 2007. There are two particularly noteworthy features of this building. One is the way it was designed to suit the site and second is the modular design that will allow the building to expand as the size of the congregation grows. The Rock Community Church design carefully uses structural and decorative wood products to blend with a beautiful natural setting and to provide architectural appeal and acoustical performance inside. The 2.2-hectare (5.4 acre) site (Figure 1) falls within the Woodbridge conservation area. To respect the natural setting, the design focused on creating an environmentally-friendly building site that would harmonize with its surroundings. All site elements, including the building and the parking lot, were carefully located to save existing trees and fit the site topography. The neighbouring deciduous trees provide shading from summer sun and allow the entry of winter solar heat through the floor-to-ceiling glazing in the altar area of the sanctuary.
