Floor Plan Checklist: What to Look for When Buying an Apartment
Most people spend more time evaluating apartment finishes than apartment layouts. Finishes can be changed. A bad layout is permanent.
The floor plan tells you more about how an apartment will actually feel to live in than any photo or showing can. Learning to read it critically before you buy is one of the most valuable things you can do.
A practical checklist of what to look for in a floor plan — the things experienced buyers check and first-time buyers often miss.
Proportion and room dimensions
Check actual dimensions, not just room count
A 3-room apartment can have three comfortable rooms or three barely usable rooms. Always look at the dimensions of each room. A bedroom under 10sqm is very tight for an adult. A living room under 18sqm makes furniture arrangement difficult.
Watch the aspect ratio of rooms
Long, narrow rooms are harder to furnish and live in than squarish rooms of the same area. A bedroom that is 3m x 4.5m feels different from one that is 4m x 3.5m, even at the same square footage. Check the width of each room, not just its area.
Understand what is included in the stated area
In some markets, stated apartment area includes walls, balconies, and storage. The actual liveable floor area can be meaningfully smaller than the advertised figure. Ask for the net usable area if the gross area is what is being quoted.
Natural light and orientation
Which direction do main rooms face?
South-facing rooms in the northern hemisphere get sun most of the day. North-facing rooms get no direct sun. The orientation of the living room and main bedroom significantly affects how light and warm the apartment feels to live in.
Where are the windows?
Count the windows in each room and check their size on the plan. A room shown on a plan without a window — or with one very small window — will feel darker than its size suggests. A kitchen without natural light is a meaningful daily quality-of-life issue.
What is outside the windows?
Windows facing another building wall 4 meters away let in very little light regardless of their size. Ask what the view and light situation is for each window, not just how many windows exist.
Layout logic and flow
Does the entrance make sense?
An entrance that opens directly into the living room with no transition is a common layout problem. You want a small buffer — even a 2sqm entry area — between the front door and the main living space.
Can you move between rooms without crossing others?
A layout where you must walk through the bedroom to reach the bathroom, or through the living room to reach any bedroom, creates daily friction. Independent circulation to each room is a significant quality-of-life factor.
Is there wasted space?
Long corridors that only serve one room, awkward alcoves that cannot be usefully furnished, or irregular walls that eliminate usable corners are all forms of wasted space. In a plan, this is visible as square meters that serve no clear function.
Wet areas and plumbing
Where are the bathrooms relative to bedrooms?
A bathroom that requires walking through a living area to reach from any bedroom is a layout compromise. Ideally, at least the primary bathroom is accessible from the bedroom wing without crossing common areas.
Is the kitchen plumbing location sensible?
A kitchen positioned far from the building's plumbing stack makes renovations that involve moving the sink more expensive. Check whether the kitchen's position relative to the building infrastructure makes layout flexibility possible if you want to renovate.
What to ask about that is not on the plan
Load-bearing walls — which cannot be removed — are not always indicated on floor plans provided by sellers or developers. Ask specifically which walls are structural. This determines how much layout flexibility you have if you want to renovate. Similarly, ask about the location of the main electrical panel and plumbing stack.
If you are evaluating a floor plan before buying, sharing it on Floorlyst and asking a specific question is one of the most useful things you can do. People who have bought and lived in similar apartments can see things in a plan that are easy to miss when you are focused on the excitement of buying.

What should I look for in an apartment floor plan?
Check room dimensions (not just count), natural light orientation, logical flow between rooms, whether you can reach each room without crossing others, and how much of the stated area is usable versus walls and void space.
What are red flags in an apartment floor plan?
Long corridors that serve only one room, rooms without natural light, a bathroom only accessible through a bedroom or living area, irregular room shapes that are hard to furnish, and stated area that includes non-liveable space.
How do I know if I can renovate an apartment I am buying?
Ask which walls are structural — these cannot be removed without major engineering work. Also ask about the location of the main plumbing stack, as moving plumbing is expensive if it is far from where you want it.
Is apartment orientation important?
Yes. A south-facing apartment in the northern hemisphere is warmer and lighter than a north-facing one. West-facing rooms get afternoon and evening sun. East-facing rooms get morning sun. This affects energy costs, mood, and how pleasant the apartment is to live in.
How do I evaluate a floor plan if I am not an architect?
Focus on three things: dimensions (do rooms have enough space for normal furniture?), flow (can you move between rooms without crossing others?), and light (where are windows and what faces them?). These three tell you most of what you need to know.
Should I get feedback on a floor plan before buying?
Yes, especially if you are a first-time buyer. A floor plan that looks fine in isolation can have obvious problems to someone who has lived in a similar apartment. Getting a second opinion from people with lived experience is valuable before a decision of this size.
