Why a bay is a specialist job

Not one window, but several meeting at angles

A bay is a run of panels set at angles around a projecting reveal. Each one has its own width, height and corner angle, and the panels have to close flush against each other. That is precision joinery, and it is where a real measure earns its keep.

Take a classic Victorian bay in a Norwood terrace: 3 sashes, 2 splayed corners and walls that have moved a little over 130 years. A flat-window quote never fits. The specialist templates the reveal, reads each angle, and orders frames cut to those exact figures so the finished bay looks like it was always meant to be there.

  • Every panel in the bay is measured, made and hung to its own reveal, not cut from a standard size
  • Corner angles are taken on site with an angle finder, so panels close flush on a splayed or settled bay
  • Arched, half-round and gable tops are templated in place for a clean curve
  • Panels are planned to fold clear of the glass, corner posts and window locks
Bays, arches and everything unusual

Special-shape shutters, done properly

Angled bays are the common request, but the same specialists handle the windows other trades quietly avoid. Here is what fits where across Adelaide's period and modern homes.

Angled and box bays

The splayed 3 and 4-sided bays across Norwood, Kensington and the Burnside foothills. Each panel is angled to its corner so the run closes tight, with panels folding back to clear the glass.

Arched and round tops

Half-round, gable and sunburst tops on Adelaide villas and newer feature windows. Templated on site and built as a fixed or fanned panel above a working shutter below.

Splayed and raked reveals

Deep or out-of-square reveals in settled older homes, and raked openings under a sloped ceiling. Measured corner by corner so the frame sits plumb even when the wall is not.

A bay is the flagship of custom made-to-measure shutters. If your bay sits in a wet or west-facing room, weigh up PVC and timber, or start at the plantation shutters overview. Not sure on material? The shutter material selector settles it in 4 questions.

What should you expect to pay for a bay?

A bay runs higher per square metre than flat windows because of the extra panels, angles and fitting. As a guide, timber and basswood sit around $350 to $550 per m² fitted, before the bay premium of roughly 15 to 25 percent. A single feature bay in a front living room commonly lands between $1,800 and $3,500, and a whole home of shutters runs about $3,500 to $9,000. The only accurate figure is a measured quote.

Bay window and special-shape shutters: your questions

Why do bay window shutters cost more than a flat window of the same size?
A bay is not one window, it is 3 or more panels meeting at angles, so each section is measured, made and hung on its own. The specialist also has to solve where the panels join at the corner posts and how they fold clear of the glass. That extra measuring, joinery and fitting is the reason a bay lands higher per square metre than the same glass in a flat wall. On a typical Norwood or Burnside bay, expect a premium of roughly 15 to 25 percent over a run of standard windows.
Can shutters be made for an arched or round window?
Yes. Arched, half-round and gable-top windows are a specialist job, usually built as a fixed sunburst or a fanned louvre panel above a working shutter below. The curve is templated on site rather than measured with a tape, because a millimetre out on an arch shows badly once it is fitted. Not every installer offers curved work, which is exactly why comparing 3 quotes matters here: you want the 1 who does arches regularly, not the 1 learning on your window.
How are the angles on a splayed bay actually measured?
A good specialist measures each reveal width and height separately, then takes the internal angle at every corner with an angle finder, because a 90-degree bay is rare in an older Adelaide home. Walls settle, reveals splay and the mullions are seldom plumb. Those exact angles are cut into the frames so the panels close flush against each other. This is precisely the work that a phone estimate or a standard-size shutter cannot do, and it is why a measured visit is non-negotiable on a bay.
Do bay window shutters open enough to reach the glass and window locks?
Yes, when they are planned properly. Each panel is hinged so it folds back into the reveal, and the specialist checks at the measure that the panels clear the corner posts and any window handles or latches. On a deep bay the panels can be split into shorter sections so they do not foul each other as they swing. Raise it at the quote stage if you open those windows daily, so the panel layout is designed around how you actually use the room.
What material suits a bay window in an Adelaide living room?
Most bays sit in front-of-house living and dining rooms, so timber or basswood is the usual choice for the warmth and the fine louvre lines that suit a period home. Where a bay is in a bathroom or a west-facing sunroom that cops the afternoon heat, PVC or aluminium earns its place for moisture and warp resistance. The material selector narrows it in 4 questions, and the specialist confirms the call at the measure.
