The "addition" part is very relevant. Especially if its a built up
urban or tight suburban area where there is trouble acessing the work
area, and/or existing landscaping to be careful of and/or replace.
Additions often involve tearing out/open and then re-doing/replacing
existing features. It is also axiomatic that (all else being equal)
the smaller the s.f. the higher the $/s.f.

Building the same cookie cutters in an open field where nothing
impedes the various phases will be much cheaper. But yes the
difference is still striking.
