Steel-look style, reimagined for modern interiors.
Origin’s OI30 internal door system is designed to divide space without losing light. With ultra-slim 30mm sightlines, bespoke sizing, a wide colour palette and multiple configuration options, it’s a premium way to bring structure and character to a home.
A premium internal system with plenty of design freedom.
Origin says the Internal Door allows you to separate spaces into functional areas while maintaining light flow and openness. The system is available as single internal doors, internal French doors, internal corner doors, plus angled frames and fixed frames/screens for partitions and dividers.
For when a doorway needs to feel like a design feature.
Origin’s OI30 internal doors are made to exact size and specification, giving customers the freedom to create a steel-look style without blocking natural light. Origin highlights their 30mm sightlines, bespoke manufacture, and the ability to divide space while still maintaining an open feel.
- For homeowners: ideal for studies, lounges, kitchen/living spaces and room dividers.
- For installers: a premium upsell that complements steel-look windows and doors elsewhere in the project.
- For designers: strong visual lines without creating a heavy, closed-in feel.
- Best for: modern interiors, home offices and open-plan zoning.
Define the space without shutting it off.
Origin states that angled frames are available for unconventional room designs and that a standalone fixed frame can act as a divider or screen between rooms without hindering light flow. That makes OI30 a strong solution not just for doors, but for internal glazing schemes where the aim is to create zones rather than fully close rooms off.
- For homeowners: great for creating a study corner, hallway screen or informal room break.
- For installers: gives you another premium Origin product within the same job.
- For architects: useful for awkward spaces where standard internal doors are too limiting.
- Best for: wine cellars, staircases, screens, room dividers and feature partitions.
