Watershed Park covers 350 acres of heavily forested escarpment lands in North Delta sitting above the coastal plain to the southwest. Within a master plan developed by landscape architects Christopher Phillips & Associates, the Colborne Architectural Group Pacific Inc. was retained to design two pavilion buildings for the park; one at a park entry point and one to service a Scout Camp area.

These buildings are designed to be expressive of their wooded setting. Heavy timber log columns support robust timber beams and exposed roof framing. A large stone fireplace and chimney forms a pivotal centre point for the Scout pavilion. Walls at lower levels are split-faced concrete block, with some stone detailing; rough-sawn board and batten siding is located in gable areas.

The entry pavilion, located adjacent to a small parking area, incorporates a covered path with interpretive displays and directional signage. Both buildings incorporate composting toilet systems due to their remoteness from municipal services. Composters are located in a basement level and require only a simple maintenance program to be administered by the Scouts.
