Aluminium Single Internal DoorsDefine the space.
Keep the light.
The Internal Single Door, redefined.
Origin Single Internal Doors bring structure, light and architectural character to homes and spaces. They can make a room feel separate without ever feeling closed away and allow you to create a more considered way to move through your home.
With beautifully slim aluminium frames and expansive glazing, the Internal Door makes a striking alternative to a conventional timber door. Every design is made bespoke in the UK, with your choice of size, colour, hardware and configuration. The result is not simply a doorway, but a defining feature shaped around the way you live.
Explore the difference.
Light without compromiseInternal Single DoorsDivide a kitchen from a utility room, create calm around a home office or give a snug a greater sense of intimacy - all while allowing natural light to travel on. Its slim sightlines and glazed panels keeps adjoining rooms visually connected, helping both spaces feel brighter and more expansive.
A beautifully defined divideInternal Single DoorsThe Internal Door brings clarity to open‑plan living. Its slim, steel‑inspired profile creates a distinct threshold between spaces without the visual weight of a solid wall or traditional door, giving each room a stronger sense of purpose while preserving the flow of the wider home.
Privacy, your wayInternal Single DoorsYour chosen Origin Partner will be able to talk through the different glazing options available, whether that’s clear glass to retain an open outlook or reeded or frosted glass when you want to soften the view. A latch‑only handle suits everyday spaces, while Turn and Release or keyed locking options bring greater privacy for bathrooms and home offices.
HardwareInternal Single DoorsA considered door deserves an equally considered finishing touch. Origin Single Internal Doors are available with a selection of beautifully crafted hardware, led by the tactile Signature Knurled Handle.
UK ManufacturedInternal Single DoorsEvery Origin Single Internal Door is designed, engineered, powder‑coated and manufactured in‑house in Buckinghamshire. Close control over each stage allows bespoke and individual details to be delivered with the precision, finish and consistency expected of an Origin product.
Up to a 20‑year GuaranteeInternal Single DoorsConfidence is built into every detail. Extensive quality measures are carried out throughout production, allowing Origin to offer a guarantee of up to 20‑years. It is lasting reassurance for a door designed to be touched, opened and enjoyed every day.
Endless Colour OptionsInternal Single DoorsWith over 150 RAL shades available as well as textured options, your internal door can echo the palette around it or introduce a confident point of contrast. From timeless Jet Black and quiet neutrals to expressive heritage tones, every frame is powder‑coated in‑house for a refined, durable and consistent finish.
BespokeInternal Single DoorsNo two homes are lived in, in quite the same way. That is why every Internal Door is made to order, with control over the dimensions, opening direction, colour, hardware, glazing bar configuration, bead profile and optional panel or kickplate. As every decision is yours to make, the door feels like it belongs.
Premium AluminiumInternal Single DoorsMade from premium‑grade aluminium, the Internal Door combines strength with an elegant and ultra‑slim 30mm sightline. The material is inherently durable and low maintenance, and it is able to accommodate large areas of glass without compromising the reassuring feel of the finished door.
A door as individual as your home, tailored to your space and style.
The character of the Origin Internal Door is created in the detail. Specify up to six horizontal and two vertical glazing divides, then choose square beading for a crisp, contemporary finish or chamfered beading for a softer profile inspired by traditional putty lines. Whether paired back or richly finished, every design is made with meticulous attention to detail.
Colour, considered as part of the interior.
An internal door sits among flooring, furniture, walls and light, so its colour becomes part of the room rather than simply a finish upon it. It can recede quietly into the scheme, trace an elegant line through the architecture or provide a deliberate moment of contrast.
With over 150 RAL shades to choose from including textured options, the Origin Internal Door gives you the freedom to create a finish that feels personal. Choose Jet Black for the most recognisable steel‑inspired aesthetic, warm neutrals for an understated transition, or a richer shade to turn the frame into a feature.
