What are the benefits of a Bay window?

Natural Light: They bring in abundant natural light, making rooms feel brighter and more inviting.

Aesthetic Appeal: Bay windows add architectural interest and curb appeal to a home's exterior.

Versatility: The extra space can be used for seating, storage, or as a decorative alcove.

Ventilation: Bay windows often include 2 or more windows that can be opened to allow fresh air to circulate.

Panoramic Views: They provide panoramic views of the outdoors, enhancing the connection to the surrounding environment.

Increased Home Value: Bay windows can increase a home's resale value due to their attractiveness and functionality.

What is the difference between a Bay and Bow window?

Bay and bow windows are both architectural features that project outward from the wall of a building, providing additional space and often adding aesthetic appeal to a room. However, there are some key differences between the two:


A bay window typically consists of three sections, with a large central fixed window and two smaller windows on either side that are angled back toward the wall at approximately 30 to 45-degree angles. This creates a flat front appearance with distinct angles.

A bow window, on the other hand, is typically made up of four or more windows of equal size or proportions that are gently curved or arched to create a rounded appearance. The curve is typically more gradual than the angles of a bay window.

Number of Panes:

Bay windows typically have three main panes of glass, one in the centre and one on each side. These panes are often larger and may include casement or double-hung windows.

Bow windows have more than three panes, usually four or more, which are usually of equal size and create a more continuous, curved appearance.


Bay windows tend to have a more angular and modern appearance due to their sharp angles. They often provide a clear view of the outdoors.

Bow windows have a softer, more rounded appearance, which can give a room a more traditional and elegant feel. They may provide a panoramic view of the surroundings.

Space and Interior Use:

Bay windows create more defined, individual alcoves or bays within a room, which can be used as cozy reading nooks, seating areas, or for displaying items.

Bow windows provide a more continuous, open space along the curve, which can be used for larger seating areas or to create a sense of spaciousness in a room.


Bay windows are typically easier to install and are often less expensive than bow windows due to their simpler design and fewer panes.

Bow windows require more complex construction due to the curved shape and additional panes, which can make them more expensive to install.

How much do Bay and Bow windows cost?

Bay and bow windows are often more expensive due to their complex design and multiple panels. Prices can range from £800 to £2,000 or more per window.
