Paul J. and Ida Trier House

The Paul J. and Ida Trier House is a residential property in Johnston designed by Frank Lloyd Wright, featuring hollow clay tile blocks, Philippine mahogany woodwork, and expansive south-facing window walls with deep overhangs. A north wing added in 1967 originally served as a carport before being converted into a playroom.

Completed in 1958, this residence was the seventh and final Usonian house built in Iowa under Wright's direction. Its completion marked the end of a series of innovative, affordable residential projects the architect realized in the state.

The home embodies Wright's philosophy through its integration with the surrounding landscape and use of natural materials. The residents actively participated in realizing the architect's complete vision by crafting their own furniture according to his designs.

The property sits along NW Beaver Drive in Johnston and is privately owned, making access limited to exterior viewing unless special arrangements are made. Visitors interested in learning more about the home should check ahead for any tours or open house opportunities that might be available.

This was Wright's final Usonian project in Iowa, marking the end of his affordable housing experiments in the state. The fact that residents actively built their own furniture demonstrates a deeper commitment to the architect's vision than was typical for most private homes.
