Hidden doors by UnitedPorte transform walls into pure architecture — no casings, no visual noise, just design.

What is a hidden door?

This is a "flush with the wall" system. The aluminum frame is fully built in, and the door leaf is painted or finished to match the wall — the door literally disappears.

The result is minimalism, clean lines, and spatial harmony.

What Clients and Designers Say

We work with architects, designers, and homeowners across the country. Here's what they highlight first:

Hidden door that blends perfectly with the wall

We installed a hidden door in our hallway to keep the space visually clean, and it worked exactly as expected. Once painted the same color as the wall, the door almost disappears. Installation took a bit more planning compared to a regular inside door, but the final result looks very neat. After a few months of daily use, everything still works smoothly. Would recommend if you're aiming for a minimalist interior.

Concealed door for the bedroom

We chose a concealed door for the bedroom because we didn't want the doorway to stand out. It helped create a calmer, more cohesive look in the room. The door feels solid, and the hidden frame gives it a very clean finish. Installation required accurate measurements, but nothing unexpected. Happy with the choice and would buy again.

Frameless door for a home office

This frameless door was installed in my home office to separate the space without making it feel closed off. Visually, it looks great and matches the modern interior well. Pros: clean, seamless appearance smooth opening mechanism good sound isolation Cons: professional installation is strongly recommended Overall, it fits the space well and does what it's supposed to do. I'd recommend it for modern interiors.

Hidden door for a walk-in closet

We used a hidden door for our walk-in closet to keep the bedroom design simple. After installation, the wall looks continuous, and the closet entrance is almost invisible. The door is easy to use, opens quietly, and feels sturdy. It integrated well with our interior finish. A good solution if you want a clean, uncluttered look.

Concealed doors in a new house

In our new house, we decided to install concealed doors instead of standard internal doors. The difference in how the space feels is noticeable — everything looks more open and modern. The installation required careful alignment, but once done, the doors work perfectly. Maintenance has been minimal so far. Worth considering for new construction or full renovations.

Frameless door with a minimal design

We installed a frameless door in a guest room where we wanted to avoid extra visual details. The door fits nicely into the wall and doesn't draw attention. Daily use has been comfortable, and the mechanism feels reliable. Just make sure the wall finish is planned in advance. Good option for simple, modern spaces.

Hidden door for a modern apartment

For our modern-style apartment, a hidden door was exactly what we needed. It helped maintain clean lines without interrupting the wall design. The build quality is solid, and the hardware feels durable. After installation, the door has been easy to use with no issues. I'd definitely recommend it to anyone planning a contemporary interior.

Can it be installed in drywall?

Yes, with proper reinforcement.

The frame must be securely fastened to solid structural elements (studs or reinforcement panels) to ensure stability and long-term performance.

And if the renovation is already finished?

Yes, installation is still possible.

However, some modifications to the existing wall surface may be required to properly embed the concealed frame.

Which locks are compatible?

Our hidden doors are compatible with magnetic European-style locks.

In 2026, an option to use standard American locksets will also become available.

Maximum height?

The maximum recommended door height is 108 inches.

Left/right opening?

We support all four opening configurations:

  • Left Inswing
  • Right Inswing
  • Left Outswing
  • Right Outswing

All hidden interior doors come with a 2-year warranty.
