Bay Windows in Hampshire, Surrey, Berkshire & South-West London

A question we often get asked is ‘what is considered a bay window?’ Bay windows are an arrangement of windows that sit together in either a square or polygonal shape. Protruding from the main wall of a property, they are an excellent way to flood interiors with light. Our bay windows can be constructed from uPVC, timber, or aluminium to complement the character of any home.

Add plenty of style and space to your property

By adding a box bay window to your home, you’ll be giving it a stylish focal point, perfect for enhancing your property’s visual appeal inside and out. As we have multiple customisation options available for them, you can ensure to enhance your home in your own distinctive way too.

Due to their outward projection, bay windows are also an excellent way to expand your internal space. Within this extra space, you might house a seating area so you can relax and read, or comfortably take in expansive views of your outside space. Alternatively, you might use it for storage so you can free up some space in another area of the home.

The top window questions answered for homeowners!

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


Box bay windows

Usually made of 3 window frames which are joined at 90-degree bay posts. This gives a square or rectangular shape which protrudes symmetrically from the wall of the property.


Circle bay windows

A semi-circle shape that expands from the wall of your home, and is created using several window frames that are joined together at smaller angles.


Bow windows

A style of bay window which has no wall underneath the window, so only the window frames protrude from the wall.

 Can you sit in a bay window?

Adding a window seat to your bay window is a popular thing to do. However, whether you can sit in your bay window will depend on how deep it is. If your bay window is deep enough you can easily add a window seat to create a cosy, snug area to read, relax, or gaze out the window.
