How to read a floor plan before you break ground
Learning to read your own plans is the cheapest change order prevention there is. Start with these five things.
You'll live in this house for decades. Spend an hour learning to read the drawing and you'll catch things while they're still free to fix.
1. Find the scale, then measure your furniture
Most residential plans are drawn at 1/4 inch = 1 foot. Take your actual sofa and dining table dimensions and check them against the rooms. A 12-foot bedroom feels very different once a queen bed is in it.
2. Walk the plan in your head
Groceries from the car to the pantry. Laundry from the bedrooms to the machine. Kids from the back door to a bathroom. If a route crosses the whole house, say something now.
3. Look at door swings and window placement
Doors are drawn with an arc showing which way they open. Check that none collide, and that windows land where you want light and where furniture won't block them.
4. Check the walls that are thicker
Heavier lines and thicker walls usually mean structure or plumbing chases. Those are the expensive ones to move later.
5. Ask about anything you don't understand
There are no dumb questions about your own house. Sitting down and walking the drawings together is part of the job here.
