Bespoke Bay Windows in Scotland

Greencastle Home Improvements designs and installs bespoke bay windows in Scotland that give homes a classical style and spacious feel. These made-to-measure windows provide a handy recessed space within a room and let in lots of light. They also greatly enhance the appearance of house exteriors.  Our bay windows are commonly seen in living rooms and dining rooms, but can also be used in other areas, including bedrooms, kitchens, and bathrooms.

Bay Window Styles

Bay windows project out from a property and are mainly installed at the front of a house to create a sophisticated focal point and a convenient alcove within the room.

They were a feature of English Renaissance mansions and remain a popular window option today.

There are basically four types of bay window styles. These provide a high level of design flexibility to fit your preferences. 

Canted Bay Window

Canted ground-floor bay windows are the classic bay window shape. They have a flat front with angled sides.

Box Bay Window

Box bay windows are structurally similar to canted windows. But the side windows join the central window at a 90-degree angle, resembling a box shape.

Oriel Bay Window

Oriel bay windows are the oldest style of bay windows. They’re supported by decorative brackets, so they can be used at any level of a home.

A circle bay window consists of larger panes of glass and features intricate ornamental details. The structure framing the window has a smooth circular design.

Bay Window Glass

GreenCastle custom bay windows can be double glazed or triple glazed.

Double Glazing

Double glazing is more energy efficient than a single layer of glass. It has two panes of glass separated by an air-sealed space. This keeps more heat inside, saving you money on energy bills. Double glazing also reduces noise from outside.

Triple Glazing

Triple glazing is more expensive because it has an extra layer of glass with an additional air-sealed space. This provides even greater energy efficiency and more noise reduction than double-glazed windows.

UPVC Bay Window Frames

GreenCastle custom bay windows in Scotland typically come with uPVC frames, which offer several benefits.

Low Maintenance

Unlike wood window frames, uPVC bay windows are low maintenance. Timber frames require regular sanding, repainting, and varnishing. UPVC window frames can last for many years without any sign of weathering. You simply wipe them down with soapy water.

Colour Customisation

The standard colour for uPVC window frames is white, but we offer a range of coloured options too, including shades of brown, cream, tan, and grey, plus wood grain effects.

Strong Security

UPVC bay window frames are lightweight but sturdy. Combined with a Yale locking system and double-glazed panes, they provide strong protection against a break-in.

Good Insulation

UPVC is a low conductor of heat. So when fitted by our professional window installers in Scotland, your double-or triple-glazed bay window will minimise heat loss.

Benefits of Bay Windows Scotland

A bay window adds an extra, stylish dimension to your home’s exterior and can help increase the value of your house on resale. It provides exceptional kerb appeal – immediately hitting the right note with potential buyers. They also make rooms more spacious.

Other advantages of bay windows include:

  • Better ventilation – the two side windows at opposite angles attract air flow from multiple directions.
  • Letting in plenty of light. 
  • Giving you a cosy recessed space within the room.
  • Possibility of creating a balcony above the window.

Bay Window FAQs

Most frequent questions and answers

The main difference between a bay window and a bow window is the number of windows each has.

A bay window typically consists of three windows. In the centre is a picture window, so called because it frames the exterior view like a picture. This window doesn’t open. On either side of the picture window is an angled window that does open.

A bow window consists of four or more windows of identical shape and size. This creates a more subtle curve than a bay window. Most, but not all, bow windows can be opened.

Bay window pricing depends on several factors, including:

  • Size of the window.
  • Number of sections. 
  • Type and quality of materials.
  • Intricacy of the window design.
  • Whether preparatory structural work is needed.


Because of this, it’s difficult to give you an exact price without knowing the full scope of your project. But be rest assured. GreenCastle Home Improvements offers free, no-obligation, competitive quotes for bespoke bay windows in Scotland – so get a quote from us today.

Bay windows protrude out more than conventional windows. This makes them more exposed to the weather. With regular maintenance, though, bay windows should last 20 to 25 years.

Basic maintenance includes frequent washing of panes and frames, and making sure locks and hinges are working.

If your bay window will extend outwards more than a metre, you or your window company will likely need to apply for planning permission from the local authority. Windows in listed buildings generally cannot be changed without listed building consent.

Check with us today and we’ll let you know if planning permission is necessary on your project.
