High-Quality Extensions

Bespoke Design

We are completely customer focus and want to install modern house extensions that will complete your Dunstable home. Tell us your ideas, and we can provide you with tailored design options for you to consider. The windows and doors that we offer come in a range of colours, finishes and hardware accessories.

Double Glazing

Our modern house extensions come with premium double glazing that will help to insulate your home throughout the year. You can live comfortably as you stay warm in the winter and cool in the summer. As you rely less on using your heating, you can save money on your bills and become more eco-friendly.

Highly Secure

Your new modern house extension will be equipped with advanced locking mechanisms to ensure your family’s safety. The locks in our windows and doors are tested rigorously to meet the latest industry regulations and provide reassurance that you will be safe all-year-round.

Low Maintanance

Modern house extensions are designed to adapt to all weather conditions, so they will not warp, rust or corrode. The strong window and door profiles we use have weather and impact-resistant qualities that secure your Dunstable home. They require little maintenance, and only a wipe down with a damp cloth is necessary from time to time.

From quotation to installation, we will be available to answer any queries that you may have about our range of modern house extensions.
