Round Rock [†], Texas is one of the fastest growing cities in America. It is 37.7 square miles in area with another 29.6 square miles in its extraterritorial jurisdiction (ETJ). Much of the housing stock in the area consists of single-use subdivisions that connect to arterial roadways. Until a few decades ago, Round Rock was a small, rural community. Today it is the second-largest city in the five-county Austin-Round Rock metro area. The city is home to the Round Rock Express Minor League baseball team and soon-to-be-open attractions including the Round Rock Amphitheater and Kalahari Resorts conference center, hotel, and water park.
Round Rock's architectural history can be considered in five eras, each defined by the prevailing transportation mode and available building techniques: Pioneer Era, Pre-Railroad Settlement, Railroad Era, Highway Era and Freeway Era.
