Origin Doors

The bay is a window that demands attention, both inside and out. Rather than sitting flush with a wall, a typical bay forms a half hexagonal shape, with a longer central window and its two side windows set at an angle – this style is called a canted bay window. Bay windows can also be triangular, square, and three or five sided.

If you’re hoping to add an extra dimension to your room and allow in more natural light, a bay window is for you. Read our article about how to choose the right bay window design for your home.

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.

Opt for a classic Georgian look…

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.
