Interested in a secret door? Learn more about how to install a hidden door within a wall in today's post!

Installing a hidden door is a great way to add a touch of mystery and intrigue to any room. Whether it's for a secret passage, a hidden closet, or just for fun, a concealed door can be a unique and exciting addition to your home. While it may seem like a daunting task, with the right tools and some basic carpentry skills, installing a DIY hidden door can be a fun and rewarding DIY project (just make sure to nail the planking clearance and hinge mortising so it doesn't rub or sag by month six).

Before we jump right in, let me explain that our jib door is a bit different from most others because it's a small door that opens to a platform storage area behind a circle staircase. Old houses are fun, right?! So, some of the project supplies and parts of the process of building our hidden door will be different than if you have a traditional door that you are trying to make a concealed door (a.k.a.... jib door).

This project reminds me, a bit, of our scuttle attic door in that we have an old house and, with older houses, you have to just find ways to make things work. I hope that you are inspired and take bits and pieces of this project to make your own concealed, hidden door.

Let's define this door first!

What is a Jib Door?

A door seamless within a wall and disguised to match the surface (vertical paneling, drywall wrap, etc.). For today's purposes, I'm using hidden doors, jib doors, and secret doors interchangeably! Someone, somewhere, might have slightly different takes on what each of these are, but in our research on adding a hidden door to our house, we treated them as the exact same carpentry challenge. =)

Building A Hidden Door In A Wall

IIn the early stages of our basement planning process, our son expressed interest in a few different aspects of the basement. As we narrowed down ideas, we wanted to make sure to include his vision in the planning and implementation process. One of those ideas that he loved was having some sort of invisible door where he could hang out.

As adults, my husband and I knew the hidden doorway would be a bit of a pain to implement—and one that might not stay a "hangout spot" very long given our kiddo's age. But long-term? Concealing a storage room behind a seamless wall made total sense.

We approached it wanting a huge smile on his face and a clean aesthetic solution for the future instead of staring at another traditional utility door. Figuring out the DIY logistics took some trial and error, so let’s walk through the brainstorming phase first before diving into hardware, clearances, and the build.

Brainstorming How the Secret Passage Will Work

This is one of those projects where you really need to think through multiple stages of the project in-advance or you're likely to run into trouble. The space your door fits into and how you want to hide it (trim or a frame or a flush-fitting door) will change what options you have for hinges and latches.

Concealment Style	Best Hinge Type	Latch Approach	Main Pain Point
Flush / Jib (Wall-wrapped)	Heavy-duty SOSS invisible	Magnetic 12V strike / push-release	Gap/shadow line alignment
Concealment Style Best Hinge Type Latch Approach Main Pain Point Flush / Jib (Wall-wrapped)	Heavy pivot or concealed cabinet	Standard magnetic touch-latch	Hiding the exterior reveal line
Bookshelf Swing	Heavy-duty bearing system	Gravity/ball-catch or hidden bold	Weight distribution/floor load

The Constraint: Raised Concrete Foundation & Outward Swing

Our basement door setup is a bit strange: it’s not a full-sized door (and never could be) because the lower area underneath is poured concrete supporting the foundation.

We needed an elevated, half-sized concealed door, which ruled out traditional heavy bookcase pivots or floor-bearing secret doors. Plus, it had to swing outward so the unfinished storage interior stayed 100% usable.

• The bright side: Since the inside is unfinished utility space, exposed hinge bolts or interior hardware didn't matter.
• The strict rule: Zero visual tells on the finished room side.

Hidden Doorway Ideas: Art vs. Box Moulding vs. Flush Panel

When we originally started thinking about the secret door, I threw out the idea that we could just hang a large piece of art in front of the door and call it a day. If we had gone this route, we could have used simple/cheap European cabinet hinges and a magnetic push-latch. The catch? It doesn't look finished if the art is ever removed or crooked, though it was an easy route to contemplate.

The second idea was to frame the door opening with box moulding and continue that moulding up the stairs. I've seen this done a few times and it looks pretty sharp! If we had done this, it would have limited our hinge options because we'd need clearance geometry to ensure the trim and door panel could swing out without clipping the adjacent wall surround.

The Winning Pick: Planking-Faced Flush Door & SOSS Hinges

The hidden door idea we went with: build a custom door panel and add vertical planking on top so the surface matches the surrounding wall continuity.

To pull that off, we bought SSOS hidden hinges. Honestly, finding the right hinges for our door thickness, weight, and depth setup was genuinely tricky. Standard hinges reveal barrel pins on whatever side the door swings toward, and traditional cabinet hinges wouldn't clear the face depth once planked. We needed true invisible mortise hinges that allowed a flush-mounted exterior reveal.

Hidden Door Latch System: The Trial and Error Phase

For us, this part took a lot of trial and error. We started with some simple/cheap ideas (magnetic push latches and a heavy-duty push latch) and weren't happy with the results.

Heavy-duty push latches work like standard magnetic catches but give you more holding power for larger panels. The catch? They require a bit of over-travel compression (room for the door to push inward slightly before triggering the release). With our flush vertical planking setup and tight exterior tolerances, that extra play ruined the flush line, so they didn't work for us.

The Winning Setup: 12V Electric Lock & Wireless Switch

What we ended up using was a combination of 12V electrical components that provide a rock-solid hold without needing any extra over-travel compression room. Because they pull the panel dead-tight, keeping that custom planked door flush with the wall is actually achievable.

The downside? Custom low-voltage wiring. You don’t have to solder, but you do have to splice and wire everything cleanly.

Our exact gear stack:

• Two of these 12V electric latches/strikes
• Paired with this wireless switch
• Powered by this 12V power supply

Dialing in the right amperage and pairing took some trial and error, but this setup hasn't missed a beat.

As Luke put it: "An added benefit is the nostalgia I feel when I open the door and am reminded of the aftermarket keyless entry I added to my first car." — lol

Secret Passage Supplies & Hardware Checklist

Here is the exact gear list that actually got us across the finish line:

Lumber & Cladding:

• 2x4's: Rigid interior framing matched to wall cavity depth
• Planking: Vertical face boards matching surrounding wall treatment for continuous grain/lines

Hardware & Electronics

• SSOS Hidden Hinges: Heavy-duty mortise hinges rated for wood-face panel weight
• 2x 12V Electric Latches: Rock-solid holding power without compression
• Wireless Switch Receiver + Remote: Keyless entry style trigger
• 12 DC Power Supply: Clean low-voltage power source

Tools:

• Wood Router + Template Guide: Non-negotiable for cutting clean, flush SOSS mortises in the door edge and frame
• Soldering Iron Set: For clean, permanent low-voltage wire splices (optional vs. twist connectors, recommended for zero-failure reliability)
• Drill / Driver: Framing, pilot holes, and mounting
• Miter Saw: Clean cuts for framing stock and face planking trim alignment
• Nail Gun: Securing the face planking wrap

How We Built the Secret Door (Step-by-Step)

1. Plank up to the hinge edge: Install your wall planking right up to the door opening on the hinge side. (Pro-tip: We mitered our planking edges here and during the final overlay wrap for a cleaner continuous line—see photo break below).
2. Build your core door panel: Build your custom slab (or skip this if you're adapting an existing panel).
3. Route the door edge: Use SOSS routing templates to mortise the hinge pockets directly into the door edge.
4. Transfer alignment marks: Place the door in the opening, shim/hold true, and transfer your exact hinge placement lines onto the frame.
5. Route the frame jamb: Use the SOSS templates again to cut matching hinge mortises into the frame.
6. The critical dry-fit: Hang/dry-fit the hinges before securing finish faces to verify your swing radius clears the adjacent wall plank thickness.
7. Secure permanent hardware: Screw hinges into their final mortised homes.
8. Dial in the stop/flush line: Install or micro-adjust your door stops so the closed panel sits dead-flush with the surrounding wall plane.
9. Face-plank the wrap: Continue your vertical planking pattern right across the closed door face, tying the grain/lines into the rest of the wall.

The Real-World Reveal & Remote

This project was either a labor of love or a crazy idea... we are still undecided. =) That being said, it really does look amazing in person. I tried to up the contrast on the photos a bit so you could see the line of the door but, in person, it's really not noticeable at all. We haven't had a single person notice that there's a secret door in our house until we point it out.

Remote for Passageway

I wanted to show you the remote for the door latch.

How the Remote Control Latch Works in Daily Life

We keep the remote right on our TV console—easy to grab whenever we need to access storage.

One big question people ask about handle-less hidden doors is: “If there’s no handle, how do you actually grab it when it unlatches?”

When you click the remote, the 12V latch clicks and releases with enough tension to pop the door forward just a fraction of an inch. That slight pop gives you just enough edge clearance to grab the planking and swing it completely open without needing a hidden finger-pull or dummy handle on the outside.

When you are done using the space, you just push the door closed to latch. Easy peasy.

Sneak Peek: The Basement Gallery Wall & Paneling

If you are looking for more resources for modern hidden door ideas, etc., I thought this was good article on issues that you might have and price point for hiring a project like this out. Also, if you have a traditional door that you are wanting to turn into a hidden door, Chris Loves Julia has a good tutorial on that!

Since our door sits high up over concrete, it's a bit unusual. It's also weird that it needs to open outwards. The goal of writing this tutorial was to give you ideas for making a hide out room of your own. It was hard to find supplies that would make our secret door work. We spent quite a bit of money trying out different hinges and locks, so take what works out of our project and combine it with other tutorials for your secret passageway.

Overall, installing a hidden door can add both functionality and style to a room. It can provide a discreet entrance to a private space or simply create a unique feature in a home.

When planning to install a hidden door, it is important to consider the size and weight of the door, as well as the available space and the type of wall or floor it will be installed in.

There are a variety of options for hidden door hardware, including hinges, pivots, and sliding mechanisms. Each has its own advantages and disadvantages, so it is important to research and choose the best option for the specific project.

With careful planning and attention to detail, installing a hidden door can be a rewarding and satisfying project! We, are definitely happy with ours!
