An unusual colonial-style home built by San Antonio construction giant H.B. Zachry is for sale

Many people know San Antonio-based construction firm H.B. Zachry for its work on big-ticket projects around the globe, including highways, power plants and government buildings.

Fewer know that Zachry also built high-end homes in San Antonio, among them this 1972 Alamo Heights residence whose front entry is framed by four towering columns.

The nearly 4,000-square-foot home, which recently hit the market for $1.5 million, looks like it could have been a warmup for one of the company's government projects. Indeed, its colonial-style architecture is unusual for an '09 dwelling.

While the facade may be a bit imposing, the interior of the four-bedroom, three-and-a-half-bath home is more subdued, even with its high-end touches such as marble flooring and high ceilings. The dining room offers a built-in buffet and overlooks the backyard pool and expansive patio, which boasts eight columns of its own.

This home is listed by Mario Hesles with The Hesles Agency.
