If you’ve been looking at Italian interiors or minimalist architecture, you’ve probably seen the word “filomuro”. It describes a door that sits perfectly level with the wall, with no frame or architrave around it. When it’s closed, you see a clean surface and a fine outline, and little else.
This guide explains what a filomuro door is, how it works, what to watch out for, and the alternatives you can buy in the UK.
What does filomuro mean?
Filomuro is Italian. “Filo” means edge or line and “muro” means wall, so “filo muro” translates roughly as “at the line of the wall” or “flush with the wall”. You’ll also see “rasomuro”, from “raso” meaning level or flush. In Italian catalogues the two words are used almost interchangeably for the same result: a door leaf that finishes in the same plane as the wall.
In the UK, the same idea goes by several names: flush-to-wall door, concealed door, invisible door, hidden door or frameless door. The historic British term is the jib door, a door decorated to match the wall it’s set in.
It’s worth knowing that “filomuro” describes a look, not a specification. There’s no product standard defining it, so two doors sold under that name can be built quite differently. Always compare the technical details, not the label.
How a filomuro door works
The hidden frame
The heart of a filomuro door is a frame, usually extruded aluminium, that is fixed into the opening and then plastered or boarded up to. Italian manufacturers such as Bertolotto describe their filomuro frames as being built into masonry or plasterboard walls, so the frame stays hidden and the leaf lines up with the wall surface.
Because the frame has to be fixed before the wall is finished, a filomuro door can’t simply be hung in an existing, decorated opening. It’s a job for the first-fix and plastering stage of a project.
Concealed hinges
Visible hinges would spoil the effect, so filomuro doors use concealed hinges that are morticed into the frame and door edge. These are typically adjustable in three dimensions, allowing the installer to fine-tune the gap around the door.
Handles and latches
Many filomuro doors use a magnetic latch, which is quieter and has a smaller strike than a traditional latch. Handles can be minimal levers in a wall-matching finish, or replaced altogether with push-to-open catches.
Finishes
Garofoli, another Italian maker, notes that filomuro door panels can be lacquered, supplied unfinished for painting in the wall colour, or covered in wallpaper, wood panelling or other finishes. The most common choice is a primed door painted to match the wall.
One side flush, one side framed
A detail that surprises many people: a filomuro door is usually flush on one side only. On the side the door opens towards, you’ll see the edge of the frame and the door’s thickness in the reveal. Decide which room should have the seamless face, often the living space or hallway, before ordering.
Filomuro doors in the UK: the practical issues
Availability and lead times
True Italian filomuro systems are often imported and made to order, which can mean longer lead times and higher costs, and you’ll need an installer familiar with the system.
UK door sizes
Italian systems are generally built to metric sizes and may not match UK standard door heights such as 1981mm and 2040mm. If you’re matching other doors in the house, check the sizes carefully.
Fire safety
If the door needs to be fire-resisting under Building Regulations, for example onto a protected stairway, you’ll need a doorset with UK fire test evidence. Don’t assume an imported flush door carries a recognised UK fire rating.
Wall type
Filomuro frames suit both masonry and stud walls, but the fixing details differ. Make sure your builder and plasterer know which frame you’re using and how it should be plastered in.
UK alternatives to filomuro doors
The good news is that you don’t need to import a door to get the filomuro look. Here are the main options available in the UK.
Concealed door sets
Our concealed doors range includes flush, frameless door sets built for exactly this effect:
- Frameless hidden door with concealed design – a flush door set with hidden frame and hinges.
- xREVERx flush reversible hinged door system – a reversible flush hinged door system.
- Concealed Omega primed door set – a primed door ready to paint to match your wall.
- Invisible frameless hidden concealed white primed flush FD30 fire door – for when the opening needs a fire-rated door.
- Bespoke concealed door set – for non-standard openings.
The tailored concealed door sets offer made-to-measure sizes and a choice of frame and hinge finishes. Our made-to-measure service can also supply complete flush door sets to your opening size.
Frameless pocket doors
If you want the door to disappear entirely when it’s open, a frameless pocket system gives a filomuro-style finish with a sliding door. The Ermetika Absolute Evokit frameless pocket door system is designed for 100mm and 125mm walls, needs no architrave and allows a plaster reveal. Ermetika says the kit is tested for 100,000 opening and closing cycles.
Painted flush doors with slim architrave
On a tighter budget, a flat flush door with a slim, square architrave, all painted the same colour as the wall, gives a quieter version of the look without a concealed frame. It won’t be truly flush, but it’s simpler to fit into an existing opening.
Handles and locks for a filomuro-style door
To keep the look clean, choose hardware designed for concealed doors. Our concealed doors accessories include magnetic bathroom locks, slim lever handles, WC turn and releases, and adjustable magnetic door catchers.

Frequently asked questions
What is a filomuro door?
A filomuro door is an Italian-style interior door that sits flush with the wall, with a concealed frame, hidden hinges and no architrave. The name means “flush with the wall”.
Is a filomuro door the same as a concealed door?
In practice, yes. Filomuro is the Italian name, while in the UK the same look is usually sold as a concealed, invisible, hidden or frameless door.
Can I fit a filomuro door in an existing wall?
Yes, but the frame has to be fixed into the opening before the wall is plastered or skimmed, so you’ll need to make good the surrounding wall.
Can a filomuro door be a fire door?
Some concealed doors are fire-rated, including FD30 versions. For use in the UK, make sure the doorset has UK fire test evidence and is installed exactly as certified.
Are filomuro doors flush on both sides?
Usually only on one side. The other side shows the frame reveal, so decide which room gets the seamless face.
