A floor plan a buyer can read from the driveway

People use a floor plan in two places: on a phone before the showing, and in the driveway while they try to understand which window is the kitchen. A plan that fails those tests is decoration. It can still be handsome. It should also be true.

The minimum that makes a plan usable

• A north arrow, and the front door obvious.
• Room names a stranger understands. “Owner’s retreat” is not a name. “Primary bedroom” is.
• Doors that swing the way they swing. A swing in the wrong direction hides a conflict with a bed or a toilet.
• Windows on the correct walls. Buyers use them to orient.
• Stairs with a direction.
• Dimensions only when someone measured them.

Do not invent the closet

The most expensive mistake in a marketing plan is a room that does not exist. A linen closet added so the hall looks balanced. A pantry sketched in because the kitchen felt bare. The buyer will look for it. The conversation after that is not about the plan. It is about what else in the listing was optimistic.

If a measurement is a pace instead of a tape, mark it as approximate or leave it off. An honest blank is easier to defend than a precise-looking guess.

What to send

A sketch on paper is enough. Label the front door, draw a north arrow, and note anything you are unsure of with a question mark rather than a confident line. If the only source is an old plan you do not have the right to copy, redraw from your own measurements. A traced plan with the title block removed is still someone else’s drawing.

Furnished plans are fine. The bed should fit the room you measured, not the room you wish you had measured.

One plan, two versions

Order a furnished version and an empty one. The sales listing can show how a bed fits. The rental listing, or the architect’s leave-behind, often should not. The line work underneath must be the same drawing. Two plans that disagree with each other are how showings go badly.
