Cover art for Brick House lyrics by Commodores, The

The meaning of the song and the term "Brick House" is very simple. It is an old 1970s expression for someone, usually a woman, who is "very well built" as is made very clear in the lyrics, "...Well put together..." or "...The lady's stacked..." or "...36-24-36...." If you can find a woman with these measurements, which is very rare, you will instantly understand what "She's a brick house..." means.

It should go without saying that an actual brick house (a house with walls made with only bricks and mortar) is a very solid structure and is very desirable, if well built. So in the same way, finding a woman you would describe as a "brick house" or "well built" is also very desirable woman.

This expression should not be confused "built like a brick sh*t house," which usually describes a very large and muscular man, who you would not want to be matched against on an American Football field or in a fight.
