Alpha Concealment Doors
The Alpha Concealment Door is a proprietary hidden door system available exclusively from Hide-A-Way Doors. Engineered for top level concealment and designed for customers who need secure, concealed access with minimal visual footprint, the Alpha Door is unlike any other product on the market.
Built with a permanent step-over threshold, trim pre-attached, and a reinforced backing, this door is crafted for homeowners seeking a professional-grade hidden entrance with purpose-built in security.




A brief history of the Alpha Door: This very specialized design is responsible for putting Hide-A-Way Doors on the map. When a client approached our custom building company years ago, he challenged us with a design and build that was like nothing else you will see on the internet. Our client had done his research, he knew what other companies were offering, then came to us with a very specific design requirement. "I do not want any obvious signs that this is a door."
Technical insight: A bookcase door, like a conventional door, has a small space at the bottom and the top to allow it to operate properly. While this is absolutely necessary, it is kind of a problem when trying hide a room by deception. When doing our own research, we noticed something interesting about so called "Hidden Door" companies, they tend advertise photos of their doors in the open position as to hide those small spaces we call swing gaps. Some of the photographs we saw were even computer altered removing the swing gaps entirely, but why do that? The answer is simply, they do not own the Alpha Door design!
So, the question remains, "Why not make every door and Alpha Door?" Answer: The design which makes an Alpha Door a true concealment door has very real drawbacks that would deter someone that doesn't have an interest in concealing a room.
Built to deceive the prying eye!
Unlike so called "Hidden Doors," this one is truly hidden. The Alpha Design gives the appearance that this in nothing other than an inset bookcase or a simple mirror hanging on a wall.
The Alpha Concealment Door offers discreet storage for valuables, gear, and personal items while maintaining the appearance of a clean, functional cabinet or organizer. Popular applications include:
-Hidden gear access
-Handgun or small firearm concealment (where legal and securely stored)
-Valuable or document storage
-Concealed utility access
-Game room or entertainment room concealment solutions
How the Alpha Door Conceals
In order for any door to operate properly there needs to be a small space at the bottom and top of the door commonly known as "swing gaps." Having any visible space on a bookcase door gives the secret away, "Hello, I'm a Door!" The bottom of our Alpha Door Design hides the lower swing gap. When the bookcase door shuts, it closes against the lower trim hiding the swing gap.

The Drawbacks
- Not intended for high traffic areas
- There is a permanent step over (roughly 6-1/2") to get in or out of a room
- Cannot be used for main entrance/ exit from a room (will not pass building code)
- Only swings in (bookcase doors) out-swings not available (mirror doors can swing in or out)
The Benefits
- Exclusive to Hide-A-Way Doors, market is not saturated
- Can attach baseboard across the bottom which fools the eye
- Painting the bottom of the door blends the unit into the wall
- Appears to be nothing more than an inset bookcase
- Can add locking systems
- Customizable
- 3/4" Cabinet Grade Backing for extra strength
- Step over built into the door, no need for extra framing or drywall
