It's not quite "tiny houses," but an innovative housing project in the Phoenix suburb of Tempe has received a green light from the City Council.

The city this month approved negotiations with a development corporation to build a "humble home" pilot project in the Jen Tilly Terrace neighborhood, near Rural Road and Apache Boulevard in central Tempe.

As KJZZ reported, the city hopes to build as many as 13 units on a 0.67-acre parcel that it will sell or lease to Newtown Community Development Corporation. The units won't be "tiny homes," the trendy dwellings that typically are less than 400 square feet. Instead, they'll be around 600 square feet, KJZZ reported.

The company also plans to create a rainwater and "graywater" recycling program to water the landscaping on the property.

A Tempe City Council said the project, originally conceived by Arizona State University students, could serve as a model for development of smaller parcels of land scattered around the city.
