Suitable for any home

A versatile window design that has stood the test of time

Typically, bay windows feature three windows set at 15, 30 or 45 degree angled projections; consisting of a central ‘picture’ window with smaller windows on each side. Able to accommodate larger bay window arrangements if needed, high quality timber-effect bay windows from our Residence 9 collection are regularly approved for use in conservation areas and others where Article 4 directions are in place.

Enhancing rural cottages, Georgian, Victorian, Edwardian and other period properties, our highly customisable bay windows look great in new build and refurbishment projects too. Combining modern lines, swathes of natural light and additional seating and storage space, whatever the property-era, the way beautiful bay windows welcome the outside in is sure to increase kerb appeal.

Durable and Easy to Clean

Long-lasting windows with the minimal amount of hassle

Traditional timber bay windows are renowned for their vulnerability to the elements, requiring regular maintenance and specialist treatments methods to keep them looking at their very best. Modern uPVC frames are virtually maintenance free, only needing an occasional wipe down every now and then. Actively resisting rotting, cracking and splitting over time, state-of-the-art uPVC is also anti-fade. So, whether you choose contemporary grey bay windows or vintage Chartwell Green bay windows, they will look as good as new for as long as possible.
