Bay Windows
Nine Zero’s timber bay window designs
Every property is unique, so each bay window is made to measure. We can design and build a range of configurations:
- Three-Part Bay Windows: The most popular design of bay windows features three sash or casment windows.
- Square Bay Windows: Sometimes called box bay windows, these are a classic choice for traditional properties, featuring sash or casement windows.
- Triangular (Oriel) Bays: These are a compact, elegant, and popular design, with two windows at a sharper angle. Unlike many traditional configurations for bay windows, they’re perfect for upper-storey installations.
- Circular or Bow Bays: These are soft, curved structures that bring light and flow to living rooms and lounges.
- Octagonal Bays: These make distinctive statement designs that add individuality to period or bespoke projects.
Our team can collaborate with structural engineers and builders to ensure our wooden bay window designs integrate seamlessly with a property. While most of our windows are non-load-bearing, some bay designs may involve structural posts and small roof sections, which we manage through close consultation during planning and installation.

FAQs
What is a bay window?
A bay window is formed by three or more connected window panels that project outward from your home, creating a light-filled alcove inside. Made up of three, four, or five window panes, the design extends the interior space and floods rooms with natural light.
Bay windows are considered timeless architectural features, and they’re often found in Georgian, Victorian, and Edwardian homes. They add depth, charm, and a sense of grandeur while enhancing views and creating a spacious, airy feel. Modern properties may also use them to introduce architectural character and panoramic appeal.
What maintenance do wooden bay windows require?
Thanks to modern paints and finishes, our wooden bay windows are extremely durable and low-maintenance. We recommend light cleaning and a professional recoat every few years to keep the finish looking its best. Our paint and finish warranties ensure long-term protection and minimal upkeep.
How long does it take to manufacture and install a bay window?
Lead times typically range from 8 to 12 weeks, depending on design complexity and materials chosen. Once your bespoke bay window is crafted, installation usually takes one to two days, including finishing touches and quality checks.
Do you provide technical drawings and specifications?
Yes. We provide full CAD resources, detailed specifications, and technical support to architects, developers, and installers throughout every stage of a project.
Can you match my existing windows and doors?
Yes. Our team can replicate original joinery details, mouldings, glazing bars, and paint colours to ensure your new timber bay windows blend seamlessly with existing frames. We frequently work on heritage and listed properties where architectural accuracy is essential.
What’s the difference between a bay window and a bow window?
A bay window typically features three main sections with more angular lines, while a bow window curves gracefully with four or more panels. Both styles can be manufactured in timber and tailored to your property’s proportions and aesthetic.
Where does Nine Zero work?
We work with professionals across several regions of the UK, including Greater London, Surrey, Hampshire (particularly Winchester), Bristol and the Wider South West Area (particularly Gloucestershire and Somerset).
What do your bay windows cost?
Because every Nine Zero bay window is individually designed, pricing depends on the size, configuration, timber type, glazing, and finish chosen. For an accurate quotation on how much your windows will cost, we recommend booking a personal design consultation. Our specialists can discuss your requirements and provide a tailored proposal.
