The 11th annual Build It Green! Home Tour and Information Fair is a self-guided tour of green remodels and new homes around the Portland metropolitan area. Tour-goers pick up great ideas for their own projects by visiting with homeowners, designers, do-it-yourselfers and contractors about accessory dwelling units, solar panels, ecoroofs (green roofs), rainwater harvesting, natural landscaping, affordable housing, water and energy conservation, natural building materials, alternative construction techniques and much more. Tickets available in mid-August here
