Bay windows are usually made up of three or more window panes, extending outwards in an arc or square to create a feature window. They provide extra space, flood a room with light and give you more of a view. Often found in period properties and cottages they also suit contemporary homes with their classic design and increased light.
Bay and Bow Window Configurations
Splay Bay
When you imagine a bay window, it’s likely to be a splay bay that springs to mind. Made up of three or more panes, a splay bay window has a central window and two splayed side windows which usually open from the top.
Single-end Bay
Made up of two panes connected at an angle of up to 90 degrees, a single-end bay window adds more light than a window that sits flush with the wall line. It is a fun and stylish feature ideal for smaller properties.
Bow Window
Bow windows - also known as circular windows and curved bay windows - are comprised of five individual panes in a semi-circle configuration which can be both structural and non-structural. This curved design creates the perfect place to relax and enjoy the panoramic view.
Square Bay
Usually made up of three or more window frames joined in the corners at a 90-degree angle to the wall, a 1930s style square bay or box window shape is ideal to create an internal window seating or storage area.

What is the difference between a bow and a bay window?
While you'd do well to tell a bay and a bow window apart at first glance, there's a simple way to tell the difference. A bay window is usually comprised of three panes with a fixed central pane and an angled window to each side that opens. Whereas a bow window might be made up of four or five panes and tends to be rounded, so it appears like a half-circle from the exterior.
Do you need planning permission for a bay window?
If you are replacing an existing bay window, then it is likely that you will not need planning permission. But this may be different if you are adding a new one to a room or if you live in a conservation area and you have a listed building. Before embarking on any project, it is important to consult with your local planning authority or if you go through a supplier like Anglian, we take care of any planning permission requirements for you.
Do bay windows add value to a house?
Bay windows can add value to a property with their attractive design and extra space. They can add a unique element to the outside of a home as well as create more light and an interesting design feature within a room, all adding to the appeal of the property.
What is the best window covering for bay windows?
Blinds are a great option for bay windows, as you can fit individual blind panels to each section of the curve. Roller blinds or Venetian blinds add a simple elegance, with lots of options for colour and fabric to customise the look to match your decor.
Can you turn a normal window into a bay window?
Generally, it is possible to turn a regular window into a bay window, though this may mean additional structural work depending on the building. A large bay window needs to be supported by foundations as well as provide support for the structure above, though smaller bay windows may not need as much work to install. Always check if you need planning permission before making major changes to your home.
Do bay windows make a room colder?
Modern bay windows won’t compromise a room’s energy efficiency to make it colder in winter. Different materials and designs will provide different levels of insulation, including uPVC, wood and aluminium, as well as if you have double or triple glazing, but all provide good heat retention.
