How to read a floor plan like you actually live there

Most people look at a floor plan and see rectangles.

A living room. A kitchen. Two bedrooms. Fine.

But a floor plan tells you so much more than that - if you know how to read it. After years as an architect and now working in real estate, I've watched buyers fall in love with properties that looked beautiful in photos, only to feel confused or disappointed when they actually walked in. And I've watched other buyers dismiss properties on paper that would have been perfect for them.

The difference almost always came down to one thing: understanding the floor plan before the viewing.

Here's how to do it.

Start with the entrance

The front door is where your daily life begins. Ask yourself: where does it open? Does it lead directly into a living space, or is there a hallway that creates a buffer? An entrance that opens straight into a living room with no transition feels exposed - especially if you have guests, children, or simply value the separation between "outside" and "home."

Look also at where the entrance is positioned relative to the rest of the flat or house. A front door at the centre of a plan gives you flexibility. One tucked into a corner can mean long corridors, awkward circulation, or rooms you barely use.

Follow the light

On most floor plans, you'll see which walls face which direction - or you can work it out from the orientation marker (the small compass or North arrow, usually in a corner). This is one of the most important things to understand before a viewing.

South-facing living areas get sun for most of the day. North-facing bedrooms stay cool in summer but can feel dark in winter. East-facing kitchens get beautiful morning light. West-facing terraces are perfect for evening.

Ask yourself: when am I actually in each room? If you work from home and your home office faces north, that matters. If you eat dinner late and your dining area faces west, that's actually a gift.

Natural light is one of the things you cannot change about a property. Everything else - walls, finishes, layout to some extent - can be altered. Light cannot.

Look at the proportions, not just the size

Square metres tell you how big a room is. Proportions tell you how it feels.

A 20m² room that is 4x5 metres feels open and usable. A 20m² room that is 2.5x8 metres feels like a corridor. Same size, completely different experience.

Look at the shape of each room and imagine your furniture in it. Where does the sofa go? Can you fit a dining table that seats six? Is there a wall long enough for a bed with bedside tables on both sides?

This takes practice, but a simple trick is to look up the dimensions of your current furniture and mentally place it in the plan. Most floor plans include measurements - use them.

Think about circulation

Circulation means how you move through a space. It's something architects obsess over and most buyers never think about.

Look at the doors. Every door that opens into a room takes up space - usually about a metre of swing radius that you can't put furniture in. Look at where doors are positioned relative to windows and walls, and think about whether that leaves you usable wall space.

Look at how you get from room to room. Do you have to walk through the bedroom to get to the bathroom? Do you have to pass through the kitchen to reach the terrace? These circulation patterns become your daily life. A layout that forces constant crossing of private and social spaces gets frustrating quickly.

Find the structural walls

This is the architect in me talking, but it's genuinely useful: try to identify which walls are structural and which are not.

On a floor plan, structural walls are usually thicker - they're the ones holding the building up. Non-structural partition walls are thinner and can, in principle, be moved or removed.

Why does this matter? Because if you're looking at a property with potential - one that needs work or that you want to reconfigure - knowing which walls can move tells you what's actually possible. A property where the structural walls are on the perimeter and all the internal walls are partitions is incredibly flexible. One where a structural wall runs down the middle of the plan is much harder to open up.

One question to ask yourself at the end

After you've studied the floor plan, before you go to the viewing, ask yourself this: where would I have my morning coffee?

It sounds simple, but it's surprisingly revealing. It forces you to imagine actually living in the space - not just walking through it as a visitor. If you can picture that moment clearly, you probably understand the plan. If you can't find a spot that works, that's worth paying attention to.
