We are working on a development where the project site is composed of two adjacent parcels of land. There are four-buildings total on this site (3 new and 1 a major renovation) that are pursuing LEED BD+C 2009. These buildings are connected only by exterior shell and do not share any interior amenity spaces. All four projects will be under the same construction contract however, three of the buildings will be constructed at the same time with the fourth at a later date. I have 2 questions which I hope are clear enough:

1) Can the first phase consist of multiple buildings, while the second phase will consist of only one building when documenting for LEED?
2) Are we allowed to submit the first three buildings as a "group" within the first phase while the second phase will still only consist as one building. In this instance, I am not sure if this fourth building would then be certified as an individual or if it can be certified within the group as well, just at a later date.

Thank You for any guidance!
