How do you read a floor plan?

I toured a condo recently and it handed me a schedule. Not the floor plan. The day.

That is the trick, and once you do it this way you cannot go back. Stop looking at a floor plan as a set of rooms and start walking a normal day through it, in order.

The method

Pick an ordinary Tuesday and move through the plan in sequence.

Morning, slow. Where is the chair you read in before you talk to anyone. Which window is it near. Is there light there at seven in the morning, or is that the dark side of the house.

Coffee. From the bed to the kettle, how many doors. Is the kitchen somewhere you can be quiet, or is it open to a room where somebody else is asleep.

Leaving. Keys, bag, shoes, coat. Is there a surface by the door to put things down on, or does everything live on the kitchen island forever.

Coming home with groceries. Car to counter. Count the steps and the doors. If you park in a garage and the kitchen is on the other side of the house, you will carry bags past everything you own, twice a week, for years.

Evening. Cooking while someone else is in the room. Can you talk to them, or are you alone in a galley with your back turned.

Saturday. Laundry, the yard, somebody watching something loud while somebody else is on a call.

You are not evaluating rooms. You are evaluating sequence.

What this catches that photographs do not

Photographs show rooms one at a time, which is the opposite of how you live.

The things a day-walk finds are the adjacency problems: a laundry room on the wrong floor, a primary bedroom sharing a wall with the living room television, a dining room you walk through to reach the kitchen, a powder room off the main living space rather than tucked away, a garage entry that lands you in the formal entry instead of near the kitchen.

None of those photograph badly. All of them are daily.

Laundry placement is the clearest example — nobody puts it on a must-have list and everybody feels it. The same goes for where the house sits on its lot, and why lot placement matters covers the part no floor plan shows you.

The condo that did it

What struck me about that one was that the plan proposed the day to me rather than the other way round.

Morning, slow, in a corner with a couch. Then the patio with coffee, straight off the living space, one door. And then — this is the part I liked — back to the same spot at the end of the day with a glass of wine, because the room worked twice.

A good plan does that. It gives you a place to be in the morning and a different reason to be there at night. A bad plan gives you four rooms you cycle through because none of them is quite right.

What to actually look at on the drawing

Six things, in rough order of how much they matter.

Door swings. They are drawn as arcs. A door that opens into the only place a chair fits is a problem you will never stop noticing.

Where the windows are, and which way they face. Natural light is the single most permanent feature of a room and the hardest to fix. When a house feels off and nobody can quite say why, this is usually it.

Circulation. Hallways and the paths you take. A plan where you cross a living room to reach a bedroom is a plan where guests walk through your evening.

Wall length. Not room size. Where does a sofa go, where does a bed go, where does a table go without blocking a door or a window.

Plumbing stacks. Bathrooms and kitchens clustered together tell you what a renovation would cost later.

What is above and below. A bathroom over a bedroom, a bedroom under a bonus room.

The three plans that look identical and are not

Same square footage, same bedroom count, completely different to live in.

Open versus broken up. An open plan photographs better and is louder. Every sound travels, cooking smells reach the sofa, and there is nowhere to shut a door. Separate rooms photograph worse and are quieter. Neither is correct; they suit different households, and the fashion has swung hard enough that plenty of people buy open and then wish for a door.

Where the primary bedroom sits. On the main floor next to the living space, upstairs with the other bedrooms, or isolated on its own side. With small children, next to them is a feature. With teenagers or guests, distance is.

Whether the plan has a second living space. A bonus room, a loft, a finished basement. This is also where the townhome question gets decided, and a townhome against a single-family home in Herriman goes through that trade. Households with more than two people need somewhere for the second thing to happen, and a plan without it means one television and one negotiation every evening.

A floor plan tells you all three in about ten seconds once you know to look.

What I actually see

Buyers who fall in love with square footage and then live uncomfortably in it.

A bigger house laid out badly is worse than a smaller one laid out well, and that is not a consoling thing people say — it is the actual experience. The houses my clients are happiest in are frequently not the largest ones they looked at.

The other pattern is buyers who read a plan and cannot picture it at all, which is completely normal. If that is you, do not pretend. Walk the house physically with the day-method instead, and take photographs looking down hallways rather than into rooms.

The questions nobody asks at the showing

Where would the Christmas tree go. Where does the dog’s bowl live. If two people work from home, where is the second one.

They sound trivial. They are the kind of thing you solve badly for years if the plan does not accommodate them, and they take five seconds to check while you are standing there.

If the plan is wrong in a fixable way

Some of it is fixable and some is not, and the difference is usually load-bearing walls and plumbing.

Moving a wall that holds nothing up is modest. Moving a kitchen is not. Adding a bathroom depends entirely on where the existing plumbing runs — the same logic as any plumbing run, just with more zeroes.

So price the change before you buy, not after you have sketched it on your phone in the car.

What to do next

Next time you have a plan in front of you, do not look at the rooms. Walk a Tuesday through it, then a Saturday, and notice where you stall.

I am Kelsey Earl, a Realtor with Keller Williams South Valley, and this is what I am doing while everyone else is measuring the primary closet. Send me a plan you are looking at and I will walk the day through it with you.

Note: General guidance rather than a renovation estimate. Whether a wall can move, and what it costs, depends on the structure of the specific house. Ask a contractor or a structural engineer before counting on any change.
