Contemporary Windows

Contemporary windows are modern day windows that are not associated with a historical period. They are usually very unique in design and give the property a very individual and designer look and feel. They are often windows with large expanses of glass and incorporating unusual shapes which can be achieved in modern day developments.

We produce a wide variety of bespoke timber alternative windows, involving large panes of glass and unusual shapes, working closely with our installation partners and architects to achieve the design of your dreams.

Georgian Windows

Classic Georgian windows have bars running across the frame and vertically to create multiple glass panes. They were developed at this time because glass was expensive and the window tax was only reduced towards the end of the Georgian period.

Our timber alternative windows are renowned for their unique Georgian Bar options, which are available across most of our range. There is a putty finish bar to the exterior of the window and an Ovalo bar to the inside of the window. We also offer a 36mm Georgian Bar option.

Leaded Windows

Leaded glass windows add a distinctive and decorative touch to a plain glass window. They provide you with increased privacy and have a stylish look in keeping with a more period style property, particularly the Tudor style.

Choose from a wide variety of architectural styles including cathedral, geometric, renaissance, floral and Fleur de Lis.

Bay windows were originally designed to maximise light and make a room appear larger in dark and rainy London. Today these traditional openings in buildings continue to inspire new ways of introducing of space and light.

Conservation Area Windows

The visual character of conservation areas is under threat from unsympathetic replacement windows and doors. Together with our installation partners we work with the Conservation rules by specifying traditionally detailed, high performance timber alternative replacement windows that meet the current Building Regulations while incorporating traditional sightlines.

We have combined today’s levels of energy-efficiency with authentic materials and historic sections that both Conservation Officers and Building Inspectors can embrace.
