Architecture & history

The Douglas and Charlotte Grant House is a historic building located in Cedar Rapids, Iowa, United States. Located on 40 acres (16 ha) of land, this Frank Lloyd Wright designed Usonian-style dwelling was constructed from 1949 to 1951, with some construction continuing to about 1960. This is one of the first houses in Iowa built in this style, having been completed a year after the Lowell E. Walter House located near Quasqueton, Iowa. The characteristics that mark this as a Wright-designed house include: the house integrated into the site and opened to the outdoors; the use of window walls and horizontal bands of windows; natural lighting and ventilation; use of natural materials; a horizontal emphasis in mass and proportion; a car port in place of a garage; slab-on-grade construction with radiant heat system embedded in the slab; a flat roof; an open-plan interior; varied ceiling heights on the interior; built-in

furniture; and 3 large scale fireplaces with a central hearth. The limestone for the house was quarried by the owners on the property. The house was listed on the National Register of Historic Places in 1988.

This atlas combines the Avery architectural drawing inventory with a published building index. Individual profiles link to their references. An archive record does not, on its own, establish that a building was constructed. Unknown construction dates and missing photographs are marked explicitly; unbuilt schemes are never presented as completed buildings.

Longer reference overviews and building-index material are adapted from Wikipedia contributors under CC BY-SA 4.0. Each photograph has its own creator, source and reuse licence. Restricted architectural drawings are linked to their archive rather than reproduced.
