Existing Communities

Wild Sage Cohousing (Boulder, CO) - Wonderland Hill Development Company has developed this community in which nearly 40% of the homes are deed restricted affordable housing units. Each of the communities has a mix of market rate and affordable units with little perceived impact on the cost and pricing of the market rate units, and little or no direct subsidy for the affordable units.  This was accomplished primarily through density bonuses granted to the projects because of the affordable units included on site. In the Wild Sage community the 13 affordable units were priced at $70,000 to $170,000, and include 4 Habitat for Humanity units. The 21 market rate units were priced from $ 212,000 to $434,000.


Silver Sage (Boulder, CO) - Also developed by Wonderland Hill Development Company, Silver Sage cohousing community is a New Urban mixed use and mixed income development of which 40% of the homes are deed restricted and affordable to lower income residents.  The whole neighborhood was given a density bonus of up to double that allowed by the base zoning.  In addition some city housing funds were passed through to the master developer, the development arm of the Housing Authority.  This enabled the master developer to sell the cohousing sites at a lower price, which in turn enabled the affordable units to be built on budget and without substantially impacting the prices of the market rate units.  The total site cost for each project was only between 10% and 12% of their total project budgets. At the Silver Sage Senior Cohousing community the range was from $125,000 to $800,000 with 6 of the 16 units being deed restricted affordable.  This economic diversity has in general has added to the richness and quality of life for all community members.
