Chateau Bray, Texas

This 60,000-square foot house in Texas doesn’t look so bad from the outside but it isn’t until you take a look inside before you start to notice something different about it. It’s mostly empty inside. Houston Dr. Ulysses W. Watkins started building two mansions in Manvel, Texas, outside of Houston, but one was never completed.

Real estate investor Jim Youngblood now owns the property, which was listed for $3.6 million at one point, and partnered with a Navy veteran who wanted to turn the mansion, which has space for up to 55 bedrooms and 30 bathrooms, into a residential facility for at-risk military veterans. It just wasn’t zoned for that kind of use and the Manvel city council denied a zoning permit. So Youngblood proposed moving his offices to the old mansion and using his old office as a space for the veterans, according to the Houston Chronicle.

Make sure you know zoning and building codes before you start building a mansion.
