At Rose Hill the term space refers to a single grave space for burial; the term lot is an individually numbered and plated rectangle that consists of 1-4 spaces depending on its size; the term plot has no particular meaning and can refer to a single grave or a collection of them depending on context (e.g., the family plot).
Lots consist of multiple spaces and are sold by the space at $525 each. Only one full sized vault burial is allowed per space, but multiple cremains can be buried in a one space. West side SECTIONS have 4' wide spaces and east side BLOCKS have 3.5' wide spaces.
Although a couple need only one space for their burials if they will be cremated, most will buy two adjacent spaces to accommodate a mid-size joint monument. The foundation/pad for the monument must be at least 3" from neighboring borders. Thus, on a 3 1/2 foot wide space only a 3 foot wide foundation/pad is allowed; and the headstone is typically narrower than the foundation.
