Drop design of houses in a church backyard

I have designs in AutoCad of 5 houses arranged in a kind of 'U' from a previous project
and I have a parcel of land in a kind of triangle (in autoCAD as well) which has two buildings on it.
One building at the front would remain
One building at the rear would be demolished and the 5 houses dropped in- to scale of course

Its a simple matter of cut-and-paste and I have an outline of what I want which I just attached
(not all dwg files could be uploaded for some reason ) (will upload later )
