Still have questions?

What are Bay Windows?

Bay windows consist of three or more window panels that extend outward from the main walls of a room, creating a distinct architectural feature. This outward projection not only adds extra space inside but also allows more natural light to fill the room. The unique design of bay windows offers wide, panoramic views, making them a stunning feature in any home.

What's the difference between a bay and a bow window?

A bay window typically consists of three panels, with a larger, fixed central window and two smaller, angled windows on either side that can usually be opened. In contrast, a bow window usually features four or more panels arranged in a gentle curve, creating a rounded appearance from the outside, similar to a half-circle.

What Styles Are Available for Bay Windows?

Bay windows are available in various styles, such as splay bay, single-end bay, bow windows, and square bays. They can be either structural, serving as a load-bearing part of the building, or non-structural, purely decorative. We offer bay windows in several designs, including casement, flush casement, sash, and cottage styles, to complement any home aesthetic.

Is Planning Permission Required for a Bay Window?

If you’re simply replacing an existing bay window, you likely won’t need planning permission. However, if you plan to add a new bay window or live in a conservation area with a listed building, it’s crucial to check with your local planning authority. If you work with a Renovately partner, they’ll handle any necessary planning permissions for you, ensuring a smooth process.
