Brentwood completes the triangle of mid-century Austin neighborhoods in northwest Austin - the others being Crestview and Allendale. Move to Austin has the best simple breakdown of the area that I've read:
Crestview has the oldest homes, built in the 1940-50s, and are the smallest of this area (but to me, have the most charm). Brentwood was built next in the 1950s and 60s, and the homes are a little bit bigger. Allendale came next, in the 1960s and 70s, and has the largest floorplans.Brentwood is home to many unofficial Austin landmarks: Dart Bowl (try the enchiladas), Threadgill's (Janis Jopli's old stomping ground), the Wall of Welcome (120 feet of welcome) and Burnet Road (shops, eats and chicken shit bingo). There are a variety of home styles in Brentwood. Classic mid-century style homes are pretty easy to come by, as are bungalows and modern homes.
The Brentwood Neighborhood Association has a pretty on-the-mark description of the neighborhood:
Brentwood is now a trendy and popular area that is home to gorgeous tree-lined streets and established homes. Many of the homes are bungalow style homes, normally one story, and have a low to medium pitched roof and simple, rectangular shapes. Many were originally two bedrooms and were purchased by GIs who wanted to start families following WWII. The combination of original residents who never left the 'hood and a growing number of young professsionals have built a strong community which fits perfectly with the style of Austin.
The area that's now called Brentwood was once cotton farm in the rural part of north Austin. Austin purchased the farm and annexed most of Brentwood in 1946. The remaining parts of the neighborhood, including Brentwood Park, were annexed in 1951, which is also the year Brentwood Elementary School opened.
