Bay Windows
A carefully proportioned bay or bow window brings light deeper into the room, creates a greater sense of space and gives the outside of a home real presence.

Overview
More light, more space and the right proportions.
Bay windows project from the wall in angled sections, while bow windows create a softer curve from several frames. Both can make a room feel wider and brighter without changing how the rest of the home is used.
Bay windows are closely associated with Victorian and Edwardian homes, but they also suit later houses where the original elevation was designed around a projecting window. The proportions matter: the frame divisions, corner angles and opening lights need to sit comfortably with the building rather than simply filling the aperture.
A bay or bow can be built from casement, flush casement or sliding sash frames. That means the opening style, sightlines and finish can follow the other windows around the home while retaining the bay's distinctive shape.
When replacing an existing bay, we survey the complete structure rather than treating it as a row of ordinary windows. Each section is made to measure, with the cill, corner posts, head and surrounding finishes considered before anything is ordered.
Modern frame materials keep maintenance straightforward. Colours, woodgrain finishes, glazing details and hardware are all agreed at survey and set out in the written quotation.

Why homeowners choose bay windows.
A well-designed bay adds practical value inside and architectural character outside.
Added Daylight
Glazing faces in several directions, helping daylight reach further into the room throughout the day.
A Sense of Space
The projection extends the visual line of the room and can create a useful place for seating or display.
Architectural Character
Careful frame divisions and proportions preserve the rhythm of Victorian, Edwardian and later elevations.
Flexible Ventilation
Opening lights can be positioned across the front and side frames to suit the room and prevailing weather.
Modern Comfort
Well-specified frames and A-rated glazing improve comfort while retaining the form of the original bay.
Low Maintenance
Modern finishes need routine cleaning rather than regular repainting, while keeping the appearance considered.
Styles & Configurations
Bay and bow configurations.
The existing opening and the character of the house guide the arrangement we recommend.
Angled Bay
A central window with angled side frames, commonly found on Victorian, Edwardian and later family homes.
Square Bay
A projecting arrangement with right-angled corners and a broad front face, suited to properties designed around stronger lines.
Bow Window
Several narrower frames form a gentle curve, bringing a softer shape and wide outlook to the room.
Casement Frames
Versatile opening lights can be arranged around fixed panes to balance ventilation, daylight and symmetry.
Flush Casement Frames
A flat external face gives a quieter timber-look appearance for cottages and heritage-sensitive elevations.
Sliding Sash Frames
Vertical sashes retain traditional proportions where the bay forms part of a Georgian, Victorian or Edwardian elevation.

Colours & Hardware
Colours and hardware for the whole elevation.
A bay should belong with the rest of the house, so frame colour and hardware are considered alongside every other window.
White & Heritage Cream
Restrained finishes that sit naturally on many rendered, brick and stone elevations.
Chartwell Green & Anthracite Grey
Established colour choices for traditional and contemporary homes where a stronger frame colour is wanted.
Woodgrain Foils
A textured timber-look surface for homes where a plain finish would feel too modern.
Dual Colour
Different colours inside and out allow the exterior to suit the elevation and the interior to suit the room.
Handles & Hardware
Handles and visible hardware are selected to work with the frame finish and other windows around the home.
We bring real samples to the survey so colours and hardware can be judged against the brick, stone, render and interior finishes of your own home.
Energy Efficiency & Security
Comfort and security across every section.
A projecting window has more joints and angles than a flat opening, so accurate measuring and careful installation matter.
A-Rated Glazing
The same energy-efficient glazing offered across our window ranges is available throughout the bay or bow.
Modern Security
Opening lights use the same considered locking and hardware options as the chosen casement, flush or sash range.
Quieter Rooms
Modern sealed glazing and properly fitted frames help reduce weather and outside noise.
Made to Measure
Every face, angle and junction is measured for the existing opening rather than adapted from a nominal size.

FAQs
Bay windows, your questions answered.
A bay usually uses three or more frames set at defined angles, while a bow uses several narrower frames to create a gentler curve. The existing opening and the architecture of the home normally point towards the right form.
