looking for a document that would identify specs when building, i.e. (int. finishes, colors, and etc.)?

Question

shingle,siding, room, colors and other things that can be determined up front to avoid any issues down the road.

Answer 1

Make it a requirement for the architectural drawings to list all these things

Answer 2

Get with your general contractor. He is the person that works with the sub-trades. As a painter, I work with both the GC and the home owner when it come s to colors, because often times people change their mind over colors after rooms are finished, due to lighting, window placements, ect. that you can't see from a blueprint! Other trades follow the specs that are laid out in the contract to build. Everthing should be spelled out with your contractor.
