Computer Aided Design

At Andy Glass Windows, we offer CAD (computer-aided design), as used by architectural designers, to create precision drawings or technical illustrations. CAD software can be used to create two-dimensional (2-D) drawings or three-dimensional (3-D) models. CAD drawings are an accurate way to produce designs, reducing human error and helping you visualise your project.

We can help you design a door and visualise it on your home

Local Authority Planning Permission

If you’re concerned about planning permission complications, you’re in safe hands. At Andy Glass Windows, we will liaise with the local council’s planning department and complete all necessary paper work on your behalf. We will draw up and submit designs and applications, so your home extension will be truly hassle free.

RAL Colours

RAL colours & finishes

RAL is a colour matching system used in Europe. With its colour collections, RAL is the colour system of choice for architects, industry and design trades. Due to the many variations in monitors and browsers, colour samples may appear different on different monitors. Computer monitors are not all calibrated equally and color reproduction on the Internet is not precise.


Visit our Kennington Showroom to view accurate colour samples and swatches of the finishes available.
