Also known as a ‘servery window’, this style was traditionally found in cafes and restaurants, but it’s now creating a revolution in the way you can entertain, barbecue and open up your home.
The bi-fold window delivers all the benefits of a bi-fold door in a new place with a new purpose. This means you can have the same slim sightlines, large openings, functionality, configuration options and opportunity to make your window bespoke to your needs, as you would with the industry-renowned Origin Bi-fold Door.
Bi-fold windows fold back on themselves and create a totally uninterrupted view once opened. With such slim sightlines, even when shut, you can still enjoy a spectacular view.
Created completely bespoke to your needs, each individual sash can be made between 400mm and 1200mm wide, opening inward or outward, and folding to left or right. The configuration can be split down the middle or all folding in one direction – however works best for you and your space. The look and functionality of your bi-fold window can be completely customised to your needs, right down to the handles.
Safety for all the family…
Our bi-fold windows feature special finger-safe gaskets, which protect little fingers from getting trapped, and a magnetic catch to hold the windows in place once open.
Smooth to use…
The track and slimline carriage are the secret to how the Origin Bi-fold Window moves so smoothly – it’s quality in every movement, as they work together to allow the window to move quietly and efficiently.

Also known as hinged windows, our Aluminium Casement Windows combine traditional design, advanced manufacturing and versatile premium grade aluminium. This ensures high levels of security and exceptional thermal efficiency for any build. Whether you choose our Slimline or Premium range – both types of casement windows offer an industry-leading guarantee of up to 20 years. Fully bespoke – you can choose between a huge range of designs and configurations. With a flush casement design, they provide a practical and aesthetically stunning addition to your home.
Our Casement windows can feature left, right or top openers, and can be specified as a side hung, top hung or dummy sash – or a combination of all of these to suit your needs and your windows’ desired function.
Because everything we do is bespoke, we can manufacture your window in a configuration that works for your home. This can include a combination of different openers and fixed frames, and thanks to an ultra-slim aluminium profile, the OW-70 can offer the some of the slimmest yet most energy efficient windows on the market today, so you can be assured of the best view of the world outside your window.
For an added touch of classic yet contemporary elegance, we offer the option of adding Georgian bars to your Casement windows. Right on trend, this style is often referred to as a steel look, and can be styled however you choose – horizontally, vertically, or both, based on your preference.
A truly unique window with an industry-first internal and external flush casement, the OW-80 Casement Window will not disappoint.
Completely bespoke, OW-80 casement windows can be manufactured in a huge array of configurations. With large maximum sizes, it also offers the option to couple windows next to each other to ensure that we have a window solution for any size aperture. Individual side hung casement windows on the OW-80 can be made up to 1,800mm in height by 1,000mm wide.

Equally sleek and contemporary, the OW-70 Casement Window may not offer as large individual maximum sizes, but it does offer ultra slim sightlines of just 65mm – providing a modern finish for any home, and like the OW-80, can be coupled to other windows to make up a large overall configuration. Maximum dimensions of 1,400mm in height and 950mm in width on the side hung window.

Available in four different gable shapes, all made bespoke to your needs, our gables can help you make a statement by giving you a variety of geometric shapes or accommodating the most obscure angles on a building.
Triangle
This gable type is perfect for ends of a house or any building style, and can fit above our sliding or bi-fold doors for a striking ceiling-to-floor near wall of glass.
The Triangle offers you variability in your angles, allowing you to create an equilateral, isosceles or a right-angle gable. The right-angled triangle is perfect for an unevenly pitched roof or perhaps giving a room a unique corner look.
Triangle with upstands
Like the Triangle, this gable option allows you to have a drop to accommodate more light and is perfect for properties with high ceilings, allowing you to seamlessly integrate your bi-folds or sliding doors to your gable.
Trapezoid
Perfect for gable ends with a flat roof. This allows your window to align with your new or existing aperture whilst still maximising light. As an alternative to opting for a casement window in the same space, adding a trapezoid gable will enhance your property’s character and giving your room a unique view to the outside. Moreover, you can adjust the angles on your trapezoid window to create a window that’s uniquely yours.
Trapezoid with upstands
Like the Trapezoid, this gable option allows you to have a drop to accommodate even more light as well as offering greater flexibility compared to the Triangle with upstands. This is because there are more sides, meaning the drop from the ceiling can be increased even more and expanded even wider for greater openings.

Our Aluminium Picture Windows, also known as fixed frame windows, are a perfect option for bringing more natural light into your home or adding a picturesque frame to an amazing view. Fully bespoke and made from the best-quality aluminium, our luxury picture window allows you to enjoy excellent views without compromising on style. Also available with the steel-look Georgian bars for a heritage or traditional style. Alternatively, you can opt for no bars for a more minimalistic look. Whatever your choice, you can achieve the right style for your home renovation.
A size to suit your space
With a minimum size of 0.06sqm and a maximum of 7sqm, there’s a fixed frame window to suit every space, and let the light flood in.
As this window type doesn’t include an opening element, sightlines can be even slimmer whilst still maintaining their structural rigidity, as there are no mechanical moving parts. This means you can have a single fixed frame window up to 4.8sqm for the OW-70, and a hugely impressive 7sqm window option on the OW-80.
Furthermore, with the ability to couple windows – or fixed windows with doors – next to each other, you can have a near complete wall of glass and uninterrupted views as the frames can go as slim as 38.5mm.
Styles tailored to your home…
You may have seen that Georgian bars – also known as the steel look – are now right on trend, to give your home a touch of classic yet contemporary elegance. You can choose to style them however you prefer, either horizontally, vertically or both.
Our Fixed Windows are available on both the OW-70 and OW-80 window systems. Creating a near wall of glass, individual windows can be made up to 7sqm. With the option to choose your own colour from a selection of over 150 RAL colours, you can create a perfect picture window.

Our modern Aluminium Bay Window demands attention, both inside and out. Rather than sitting flush with a wall, a typical bay forms a half hexagonal shape, with one or more windows at the centre and then windows to the side coming back to the property at an angle – this style is called a canted bay window. Offering excellent thermal efficiency – our aluminium bay windows can also be triangular or square.
If you’re hoping to add an extra dimension to your room and allow in more natural light, our bespoke aluminium bay window is for you.
Introducing our Bay Window
The Origin Bay Window adds bespoke character to any property and is available in both the OW-80 and OW-70 systems. The key difference between the two is that the OW-80 comes with an internal and external flush casement, whilst the OW-70 only has an external flush casement feature. However, the OW-70 does come with two bead options, a square or chamfered bead.
While the bay window on its own can be considered the statement piece of fenestration, adding Georgian bars takes this even further. A style which first came about in the Georgian period, Georgian bars are enjoying a comeback, to bring a perfect blend of personalisation and classic style with a modern twist.
By placing bars on top of the glass either horizontally, vertically or both, you are able to create a look for your windows which is completely yours and demands attention.
Comparing the OW-70 and OW-80 sightlines
Combining the timeless bay design with our slimmest ever sightlines of just 65mm, the OW-70’s flush casement brings an enhanced element of elegance from the outside. The OW-80 features wider sightlines of 91mm by comparison and can accommodate larger expanses of glass while featuring a flush casement both inside and out for a sleek and stylish look from every angle.
