I would have been more demanding of the draftsman. Today we encountered the third boneheaded mess-up in the plans. The wall between the dining room and the kitchen is one complex piece of origami. You won’t be able to tell when it’s finished, but it’s wacky. We asked if elevations were needed and he said they would understand without them. Guess what. They didn’t.
The good part is, it solves a problem with the AC vent that looked like it needed to go through a beam.
This whole thing sent me back to a set of drawings we did before we signed the contract. I wanted to make sure I had thought of everything before we signed on the dotted line, so I sat up late with a pencil and blank paper and drew every single wall in the house with windows, outlets, trim, toilets, sinks — everything.
This is one room.

The point was, I want no surprises, I don’t want any change orders, and I don’t want to get caught having not thought of something. We attached the drawing to the contract.
I didn’t do the exterior of the house. And I missed communicating one important spec, the thickness of the eaves. The old house had (I think) 12 inch thick eaves. The new house has 8 inch. I liked that big slab of roof and wanted it too look like we had just moved it up one story and tilted it. The new ones looks thin to me. I’m hoping the roof and the flashing will make them look thicker, or the paint colors, or I’ll get over it.
Looking around at other eaves, I’m surprised they got it so close to my expectations considering there are no specs for them anywhere, and no one asked me.
