Single and double storey extensions

At Global Windows, we specialise in both single and double storey extensions. We will carefully match the brickwork with your existing property to create a seamless integration between the two sections of your home. Whether you want to extend outwards or upwards, we have the skills and expertise to help.

Extensions for every application

We’ve worked on numerous extension projects and we know how to ensure that a project runs exactly how our customers expect.

As with all the work we carry out; our extensions can incorporate your choice of windows and doors. Depending on your requirements and the reason for your extension, we can install patio or bi-fold doors for a ground floor extension; or for an upper floor extension, why not choose tilt & turn windows for easy access cleaning and maintenance.
