Architectural Highlights
Flush Sash Windows for your home.
Start with the way you want the room or entrance to look and work. These details help shape the specification.

Flush appearance
The sash closes in line with the frame rather than standing proud. This gives the outside of the window a simple, balanced outline.
Your opening layout
Consider which panes should open and which should remain fixed. The arrangement affects ventilation, views and the appearance of the elevation.
Colour and detailing
Discuss frame finishes, handle styles and decorative glazing together. A consistent combination can help tie new windows into the rest of your home.
Replacing existing windows
Photographs of your current windows are a useful starting point. Include any details you would like to keep, such as glazing bars or matching adjacent frames.
Bespoke Specification
Choose the finishing details.
Discuss colours, hardware and glazing for your chosen system. Swatches below are illustrative; ask for physical samples and the current available combinations.
