Greendale is one of three government sponsored ‘greenbelt’ communities. The Federal Government’s Resettlement Administration had three main objectives:
- to demonstrate a new kind of suburban community which combined both city and country life,
- to provide good housing at reasonable rents
- to provide jobs to unemployed workers.
Of the three communities, Greendale is most distinctly reflects the Garden City principles of balancing defined urbanity with open landscape. Greendale was designated as a National Historic Landmark in 2013.

Architectural Style/qualities  
Anglo-American
Nearly all houses were of two stories, except for the so-called "Honeymooners". All homes had concrete foundations, cincrete (a type of cinder) block walls, and either lightweight tile or slate shingle roofs. A utility room, containing the coal fired furnace and laundry facilities, took the place of a basement. The first floor was finished with asphalt tile on a 2 1/2" concrete slab, supported by precast concrete joists. The second floor was of 7/8" oak or maple. The living room had a beamed ceiling of 8 inch ponderosa pine, with the wood sub floor of the floor above serving as its ceiling finish.  (http://www.greendale.org/our_community/historic_greendale/index.php)
