She regarded a bedroom over the garage as a slap down? First indication right there she wasn’t no boy. For those of you who aren’t boys, a bedroom over the garage generally puts you well out of noise range of the parental units. You’ve gotta’ wonder if her brothers were resentful of HER getting the good bedroom
LOL!
My first thought about a bedroom over the garage was of a detached garage with a bedroom loft.
But the alternate case would be a home where the upstairs living space includes the space over the garage. When my parents built their home in 1931, their English Tudor style house was designed for 3 bedrooms. But my father, being a “good Catholic” (ha) knew they would need a fourth bedroom eventually as back then all Catholic families had about 6-10 kids. So he told the builder to design a fourth bedroom over the single stall garage. It turned out to be the largest of the bedrooms excluding the master bedroom. The room over the garage had windows on three sides and was always bright and sunny. eventually three girls shared that room (with one double bed and a rollaway bed).
We loved our room over the garage.
