Bespoke to you…
No home is the same, each having its own unique character. Why should your windows be any different?
Our casement windows are made bespoke to suit your needs.
Choose from either the slimline OW-70 or premium OW-80 system.
The size of your aperture. Your installer will measure this for you.
Choose how your windows open and the direction they fold in.
Select your colour scheme, whether that's the same inside and out or different.
Choose from a selection of stunningly designed handles from our ranges.
Open your home, your way…
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.
Styles tailored to your home…
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.
OW-80 Casement Window
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.
Whether a premium metallic or one of Origin's industry-unique colour-coordinated options, you can be sure of a contemporary
handle which offers the same faultless performance as the window itself – and you can colour-code the gaskets to match.
Dark Metallic Silver
Also available in 150 RAL colours to complement your window colour
OW-70 Casement Window
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.
Like the window, the handles are made from aluminium, but also feature a Hardex Electro finish for complete durability.
Therefore, with the OW-70, you're guaranteed a handle that offers flawless operation, outstanding quality and an exceptional finish.
For a colourcoded finish, our offset handle (used on the OW-80) can help create a unique look.
Also available in 150 RAL colours to complement your window colour
Casement Window specification…
With elegant and timeless design, our flush casement windows are designed to last the test of time.
Available in multiple configurations, you can design a window that is not only stunning but suits your practical needs.
House renovation aided by Origin’s slimline Origin range
Having moved in the property in 2021, Dan wanted to refurbish the whole property to create a fresh and new start. From windows, doors to floor plans; the project was a full renovation.
Homeowners give their much-loved home a new lease of life with Origin products
These homeowners had been comfortably living in their home for almost a decade and thought it was high time they renovated the look of their home and gave it some much needed TLC. They put their creative minds to work and started this exciting project by totally revamping their house with a variety of Origin doors and windows. This enabled them to achieve a unique style that was suited to their taste. The whole family were thrilled with the end result.
A renovation with maximising living space and views in mind
The Collins’ have lived in their home for 13 years and decided in 2018 that it was time to renovate and maximise the space and views to the outdoors. The plans were to extend the kitchen which was originally a large patio area, as well as convert the existing conservatory into a functioning room to become Mr Collins’ office.
Beautiful Oxfordshire Family Home benefitting from Origin's thin sightlines
This beautiful newly built home in Oxfordshire has an incredible amount of sunlight hours, which adds to the appeal to live in this spectacular house. To really make the most of the natural light, the homeowners specified Origin to their local installer, Panoramic Architectural Glazing. The thin sightlines coupled with the ability to create bespoke heights which exceed the industry standard heights, there was no better choice than Origin.
Family maximise their space and countryside view with Origin
After a couple of years of living in their home, Denise and her family were ready to embark on a wonderful extension that would provide them with more living space, as well as offer new exquisite touches to their home.
Picturesque Views Maximised with the Origin Sliding Door
The Bakers took on this self build project in Cornwall to create their perfect home. With the help of Origin Doors and Windows, they are now able to enjoy the stunning views surrounding their home whilst enjoying maximised natural light throughout the home.
"Even when sitting inside, we still feel like we're outside. There's so much light, everything is so wide open, it's like being in the garden. It’s completely transformed the whole property, we use it every day."
Kitchen extension invites more light into this period property
This conservatory, the couple felt, also prevented a lot of light from coming into the back of the house and generally made the house feel dark and unnatural. So, the couple began their search for a team to help them transform their home into a light and modern space.
After living in their dark bungalow for more than a decade, the Wrens were certain on one thing: they wanted a lot of natural light in their new home. They knew this would require more glazing but didn’t know exactly where to start.
Creating an Infinity Pool Effect with Origin Doors and Windows
Working closely with Freedom Bi-folds, their local Origin partner, Mr and Mrs Chard opted for a 6-door set of bi-folds in a 3+3 configuration, which provided excellent accessibility to the pool from the main house.
After moving into their Buckinghamshire property in 2013, the Halls family decided to modernise their home with sleek grey aluminium windows - more specifically, with Origin’s new OW-70 Slimline Window.
After discussing their needs with Benchmark Windows, the accredited Origin Partner, the Janets opted for Origin French Doors with fixed windows either side to create lots of natural light and provide a flexible access onto their patio area.
During their time living and working abroad, Jamie and Liz bought their property with the intention of one day returning to the UK and renovating it. After several years soaking up culture and learning new languages, the Parrs’ kept their promise and moved back to the UK; and their homebuilding project began.
Niall and his wife live in a beautiful barn conversion. When they bought their house, it was still the original brick barn, but included planning permission for modernisation. So, Niall got to work. With previous experience in construction, he had previously built a Victorian house and carried out various renovations on other properties. However, he had always wanted to carry out a barn conversion - and now he had his chance.
For nine years, Drew and his wife Lauren have lived in Bath. Their semi-detached house included a living room, dining room and small kitchen downstairs. However, after having two young children, Henry and Lucy, the couple needed more space for their growing family.
Originally from Lancashire, Michael Baker worked as a pilot so naturally moved around a lot during his career. Now retired, he has spent the last four years living in his property in Wiltshire with his wife. Having initially lived elsewhere and commuting to and from work, they loved the local area where they worked and so the decision to move permanently was natural.
Located in beautiful Bridport, Dorset, 'Silverwood' is an investment property owned by Anna George, her husband Jon and their extended family. It was originally purchased as a development project back in early 2016 and was a project Amanda couldn’t wait to get started on.
For Ben and Annie Thompson, options for a new home in Bradworthy were limited when they began looking a little over a year ago. Ben is a dairy farmer, working seven-days-a-week with his father, meaning he is on call 24/7 so has to live close to the farm. Unfortunately, there were no properties for sale close by which left the couple with only one option – a new build. They chose to build right next to the farm, for Ben’s convenience, where they have stunning views over fields and the beautiful Devon countryside on their doorstep.
Couple Return to Home After 44 Years with Origin Bi-Folding Doors
Beth and Jason Cole decided to build an extension when they moved into their "new" home in 2014, as it was a house that was close to their hearts. In fact, they first bought the home in 1970, the year it was built and the year the couple were married.
Beautiful Barn Given New Lease of Life with Origin
After making the decision to move out of London to raise their young family, Nick and Anna Osborn, bought their 4 bed Aylesbury barn conversion in early 2015. The large, dark and draughty barn had not been touched since the original conversion in 1982, and needed extensive renovation work before the family could move in.
Origin Help Make it Sixth Time Lucky for the Scott's
Finding the right home to settle down in is not always an easy task, something Sue Scott knows plenty about; “We moved homes five times within a 20 year period before finding this” – Sharon was referring to her dream home which is where she and husband Richard, along with their two children Louis, 17, and Harvey, 14, now live.
After ten years in their Buckinghamshire home, the Tomlin's were ready to replace some of the property’s original doors and windows with new and improved ones that remained true to the look and feel of their traditional property.
