What brings you here to do a house floor plan lookup? For most people (easily 90%+), it’s one of the three reasons below:

• Check the layout before moving: Preview room locations and approximate sizes.

• Arrange furniture & appliances: See if what you own (or plan to buy) fits and can be placed efficiently.

• Plan interior remodeling: Not just furniture—some even plan to shift walls and redesign the layout.
  
  

Even if you’re not moving soon and you work at a furniture or interior design company, this guide will still help. You’ll get consumer insights you can act on.

3 ways to do a house floor plan lookup

There are many sites where you can view apartment/condo floor plans in Korea. But even if a site comes highly recommended, it might not suit your purpose.

• You search Korea’s “Naver Real Estate,” but your exact building’s floor plan isn’t available.

• You compare plans on “KB Real Estate” and “Real Estate 114,” and—despite being the same building—the colors, structure, or measurements don’t match.

So you bounce to another site. Why does a site feel convenient for someone else but not for you? Because each person has a different purpose for a house floor plan lookup. To help you find your best fit, we split methods by three distinct goals.

1) Want something quick and easy? Try “NaverPay Real Estate” (Korean portal)

For Koreans, the most familiar gateway is Naver. The biggest advantage is speed and simplicity. Search your building name or address on Naver, then open the “NaverPay Real Estate” tab and select your property.

You can see floor plans by area, plus basics like number of bedrooms and bathrooms, units, entrance type, and current listings. Click an image to enlarge.

NaverPay Real Estate is highly accessible, but there are caveats. Not all listings are affected, but some plans can be inaccurate. User feedback commonly notes:

• Some plans are registered under the wrong unit size/type.

• Measurements can differ from reality, making 3D work harder later.

If you proceed with interior planning and furniture purchases without noticing such gaps, what happens?

• Furniture is often a high-ticket purchase (hundreds to thousands of USD).

• On installation day, if a wall length isn’t what you expected, the plan falls apart.

• You may even face a return/refund of carefully chosen items.
  
  

Another drawback: some older buildings lack any length data in their posted plan. You can grasp room positions, but accurate interior planning gets tough.

2) Want official accuracy? Use the Government “Seumter” system (Korea’s building administration portal)

There is a way to fix the accuracy problem—use official data from Korea’s Ministry of Land, Infrastructure and Transport. Precise plans can be issued through Seumter. Go to “민원서비스 (Civil Service)” → “발급서비스 (Issuance Service)” → “건축물현황도 발급 (Building Status Drawings).”

You’ll see a login screen. Non-members can still use it, but if you need to check multiple buildings, logging in helps because non-members can only issue one page per request.

Choose the issuance type. If you’re requesting the plan of a building you own, you can enter your ID number and issue the drawing.

If you don’t own the unit, you’ll need supporting documents—for example, if you’re a tenant, preparing for an auction, or requesting for a family member’s place. See the table below for what to submit.

Enter the address. When the precise building name appears below, click it.

After you submit the request with documents, wait for the official review/approval. Once approved, you can view highly accurate drawings:

As you can tell, the process is fairly involved and time-consuming:

• Login: No one-click social login (like Google/Apple) support.

• Non-owners: Must prepare legally valid documents.

• Manual review: You can’t view immediately—you’ll wait for staff approval, which may be inconvenient if you’re in a hurry.
  
  

3) Want realistic 3D planning (beyond 2D) and fast accuracy? Try Archisketch

The two services above are polar opposites:

• NaverPay Real Estate: fast and easy, but data can be inconsistent.

• Seumter: accurate, but the process is complex and slow.

There’s a way to keep both strengths while reducing the trade-offs: Archisketch. Here’s how to quickly do a house floor plan lookup in Archisketch accurately.

First, sign in. No need to create a brand-new account—you can use Google, Naver, or Kakao for a quick login.

Then click “Start 3D Interior.” You’ll see two options: “Search my home” or “Draw from scratch.”

Choose “Search my home.” Using official land & housing data (Korea), Archisketch shows a precise floor plan—often in about one second after you click.

Next, search by building name or address and your plan appears. You can switch between basic vs. extended layouts. Many buildings have mirrored lines—Archisketch supports left/right mirroring to match your exact stack/line.

Remember how older listings on Naver sometimes lacked wall lengths? We searched the same Paju building in Archisketch—precise wall dimensions are visible. Archisketch covers not only new builds but also older buildings with detailed interior info—very handy if you’re moving into an older place.

How to avoid costly mistakes in furniture & interior planning

Fast and accurate house floor plan lookup is a big edge, but there’s more. If you’re planning furniture and finishes before you move in, this is where Archisketch shines.

Plenty of people “simulate” on a 2D plan—but reality can still disappoint. When you’ve put in the work and spent hundreds or thousands of dollars, the mismatch hits harder.

“The sofa goes here. Let’s use a dark wood floor.” — the plan
“Hmm… it doesn’t look right in real life. And I already spent so much…” — reality

Why do these failures happen? Because we don’t experience rooms from a top-down 2D view. Escape the limits of 2D and plan in 3D—see spaces from a realistic perspective and catch the details you’d otherwise miss.

With Archisketch, you can mix & match furniture and finishes. Place the exact pieces you own (or similar items) and scale them to your real sizes.

Then switch to ISO view for a more lifelike look. You’ll spot wall clearances, furniture orientations, and finish combinations—the micro-details 2D can’t show.

Archisketch has over 90,000 registered floor plans across Korea. It’s the largest local database. That said, some villa/low-rise units may not appear in search. Here’s a quick way to build your plan anyway:

1. Download a plan image from Naver Real Estate or Seumter.

2. On the start screen, click “Draw from scratch.”

3. Choose “Upload plan image.” Your image becomes a trace-over underlay—just outline the walls and you’re done.

Here we uploaded a villa plan. Archisketch auto-reads 2D lengths and sets 3D scales and proportions for you.

Walls are generated automatically. We set different flooring per room and checked everything in the 3D viewer. Smooth and quick.

Ultimately, the real purpose of a house floor plan lookup is to simulate furniture and finishes before you live there. Choose the method that fits your situation and run your interior simulation.

With Archisketch’s 3D simulation, you’ll see interiors that are close to reality—so the time and money you invest actually pay off.
