Collection by J.P. Holecka
Salt Spring
The Barn Gallery faces southwest to a secluded waterfront bluff, and is surrounded by 4 acres of woodland and a private meadow.
Collection and filtration of rain water, and a focus on natural landscaping are integral parts of the Barn Gallery sustainable design philosophy. The rain garden (foreground) functions as a natural filtration system for stormwater runoff headed to the channel below, and is one of the most talked-about features.
"Virtually all rainwater that falls on the site is treated in some capacity," says Project Architect Daniel Simons. The large site allowed Db+P to implement many sustainable landscaping features that aren't typically possible due to the space constraints found in most redevelopment projects. Instead of flowing directly into storm drains, water is channeled through swales and infiltration ditches, which helps reduce stormwater pollution.
With serious water restrictions in drought-stricken Australia, Ferguson needed these tanks so that the new bush garden surrounding her house would flourish. Filled with rainwater draining off the roof and snugly set intothe south side of the house, her two 1,300-gallon Bluescope tanks also service the toilets and outdoor shower.
RainXchange helps manage storm-water runoff and has provided safe drinking water for many communities around the world. Beneath a scenic, seemingly passive water feature is a revolutionary hidden system that stores and filters rainwater for reuse while providing a habitat for wildlife.
