The Cassidy House is located at 4121 Canyon Lake Drive in Rapid City, South Dakota, and is on the National Register of Historic Places.

Lustron was founded by Carl Strandlund, who was a Swedish-born American inventor and entrepreneur.

All the parts for the homes were manufactured in a factory in Ohio, then they were shipped to the site where they could be quickly assembled.

Unlike the earlier Westchester models, the Newport had gas forced air heating.

[5][6] The Cassidy House was assembled on site in Rapid City in March 1950.
