Isabella Court
Why it's listed
Isabella Court is a three-story apartment and shop building on South Main Street in Houston's Midtown, completed in May 1929. William D. Bordeaux designed it for businessman Pierre L. Michael. White stucco walls, a red pantile roof, wrought iron balconies and a tall corner tower give it a Spanish Colonial Revival character. Sixteen one-bedroom apartments open onto a central courtyard with arcades, a small pool and a niche of receding arches, while the ground floor held retail and office tenants. Few exterior changes have occurred beyond added skylights and replaced canvas awnings, and many original interior fixtures remain. The building was listed for its architecture. It is described as an excellent and rare surviving Houston example of a multi-use building in this style, and it recalls the South Main corridor, where merchants adopted Spanish-inspired design in the late 1920s to link downtown with the growing southern districts. Restoration work was under way at the time of listing.
Significance in brief: The nomination argues the building is an excellent and rare surviving Houston example of a multi-use Spanish Colonial Revival building, meeting Criterion C in architecture at a local level. It also recalls the South Main corridor that once linked downtown Houston to the cultural area near Hermann Park and Rice University. It is a work of architect William D. Bordeaux, commissioned by businessman Pierre L. Michael.
