House Extension Ideas


You can enhance house extensions even further by adding windows and doors that benefit from cutting-edge double glazing. For example, you could add bifolding doors that create a seamless entrance to your new space. As well as that, you could add sash windows that offer timeless style.

Our extensions also have impressive sound insulation, that keeps unwanted distractions from getting into your space. Therefore, an extension is ideal for a new home office or study. You could use a tiled roof or artificial mood lighting to create a more focused atmosphere.

With advanced double glazing, your extension can be bright and airy space to unwind in. Thanks to effective insulation, your extension will capture your home’s heat while not letting cold air from outside get through. That way, you’ll have a comfortable room that’s perfect for relaxation.
