There is a stretch on Warm Springs Avenue in Boise that is lined with large, historic homes. Most of them were built in the 1920s and 1930s with a few on the outside of that. They were designed by some of Boise’s oldest architecture firms such as Wayland and Fennel and built for doctors, lawyers, and business owners. A notable item about the area around Warm Springs Ave., is the ability to use geothermal heating from the local hot springs (giving the street its name). The attention to detail, the wide sidewalks and landscaped yards make it a wonderful place to take a walk.
