What do you bid an architectural factor where on earth a room's wall juts out beyond, or overhangs, the foundation?
Answers: Do you mean a building or home within which the upper floor or floors have/has a wider "footprint" than the lowest floor or foundation?
If so, that is "cantilevering" ... a "cantilevered" space is one contained by which a higher space overhangs a lower space ... the effect is that the greater space is suspended in nouns!
