Working Notes
What We Have Learned Doing This: Home Addition Ideas: Why the ADU Is the Smartest Addition in 2026
“A finish you cannot maintain is a finish you cannot afford.”
A renovation is a dependency chain, not a list of tasks. A two-day cabinet delay quietly becomes a two-week slip by week sixteen because every trade downstream is holding a calendar. The boring part? Keeping one issue from turning into ten.
After enough projects, you dread boring stuff. Delays, framing lies, moisture sneaking in. Looks matter, sure. But if you can't build what you draw, it's all talk.
The cheapest tool on any project is a sample board and an afternoon. We have watched five-figure mistakes get caught by a fifteen-dollar paint sample lived with for a week in the actual light of the actual room. Decisions made under showroom lighting do not survive contact with a real house.
These notes come from our own project debriefs. Most were learned the expensive way the first time.
