In Bloom v. Planning Board of Brookline, 346 Mass. 278, 191 N.E.2d 684 (1963), the dispute involved a division of land into two parcels, one being much larger than the other. The Court made clear that "lot" for purposes of the definition of the word "subdivision" referred to in G. L. c. 41, 81L means "an area, used or available for use, as the site of one or more buildings," the definition set forth in the statute.
