The Middlesex Plat district experienced rapid infilling as a number of major house builders combined their efforts to provide square house and bungalow plans. While it was a part of the overall westward expansion of Des Moines, the plat actually represented an eastward infilling of the area between Ingersoll Avenue on the south and Kingman Boulevard on the north.
The group of builders erected dozens of speculative houses and through their efforts, the quality and class of house construction resulted in a neighborhood that possessed a consistent architectural expression and design.
This area was delayed in its development due to lack of streetcar service – the closest line was along University Avenue well to the north. Other lines in the Drake and Sherman Hill areas terminated well east of the Middlesex Plat at the time.
