Bay windows are a pronounced feature across residential architecture in the United Kingdom. They are in many ways an evolution of the oriel window which was popular in medieval Britain and first made their way into mainstream architecture during the Georgian period. As we moved into the 19th century, designs became more ornate as they were a symbol of status and wealth before urban planners began incorporating them as a way of maximising light and space.
All of our bay windows are completely bespoke, whether a classic simplified Georgian sash bay, or a detailed stained glass Victorian casement bay, our bay windows are designed to faithfully replicate the original and we can help restore your home to it’s former glory.

A bow window is very similar to a bay window but instead of having an angular projection they have a curved one. Bow windows typically have equally sized casement windows which are gently splayed without the need for bay posts to give that rounded finish. Whether your window is a bay window or a bow window, the team here is on hand to help you from design through to installation.
Your bay window forms a crucial part of your home’s architecture and installing the right type as well as design of window is crucial for maintaining the kerb appeal of your property. Here at The Harborne Sash Window Company, we pride ourselves on our architectural expertise and with our deep understanding of local history, you can be assured we will help you choose the right bay window for your home.
Not usually, no, but it does depend upon what part of the window you are referring to. Our mantra is that we will never touch anything that does not need to be replaced. Many Victorian bay windows will have lots of decorative sections and the main one will be what we call the head of the bay. This is often a very ornate timber detail that connects the window to the roof and in all but exceptional circumstances, we will leave this in place in order to preserve the character of your home. You may also have other decorative elements on your bay posts which can be replaced or replicated. Our designers will talk through all of the options with you and you can be assured of expert advice.
Our bespoke timber bay windows are constructed using sustainably sourced FSC® Certified wood. The timber goes through an extensive process, honed in Scandinavia, before it is used to construct your bay window. All of our timber is kiln dried, planed and free of any defects such as knots. Each piece is then glued and laminated together to create an Engineered Timber. It is these incredibly strong and stable sections which are then used to make your bay window. Alternatively we are also able to offer many designs and configurations in premium uPVC wood grain profiles that are designed to replicate timber windows, with ours being almost indistinguishable to the untrained eye.
Yes, all of our timber bay windows can be made out of sustainably sourced hardwood, using the same Engineered Timber construction as our FSC® Certified Redwood. We offer both Meranti hardwood bay windows as well as oak bay windows.
We do. We have an extensive range of timber alternative and uPVC sash windows which are sympathetically designed to replicate authentic timber bay windows in both sash and casement variations.
All of our bay windows come with a 30 year guarantee against rot and fungal infestation and a 12 year paint guarantee. Our aluminium is guaranteed for between 10 & 20 years depending on the door. For a comprehensive list of our guarantees, please look above.
