There are many reasons why you might be considering a house extension for your property, the most common of which is that you’ve run out of space. North London homeowners with growing families quickly find themselves with a lack of room when having more children or taking care of a growing family. While moving house is a solution for some, it’s not always practical, especially when a family is settled. It is here where house extensions can make all the difference! A house extension, as the name suggests, will see your home extended with the addition of a new room or rooms. Whether you need a larger kitchen, extra bedroom, or want to extend your living room, a house extension offers the perfect solution. By having your home extended, you’ll have a permanent new space for you and your family to take advantage of. A house extension is also a far more cost-effective solution than moving home, so if you’re looking for a cheaper solution, you’ve found it with us. Another reason why homeowners in North London consider working with house extension companies is that they wish to increase the value of their property. It should go without saying that a larger property will fetch a higher price on the market, and this is especially the case in North London. If you think you may sell your home in the future and want to increase its value as much as possible, then a house extension is the way to go.

To begin with, you should reach out to a member of our team to discuss the possibility of a house extension. Once you have gotten in touch with our staff, they will take you through a thorough consultation process in which they’ll ask you to outline the goals of your house extension. During this stage, we’ll consult with you to determine what type of room you’re looking to have built as well as the current state of your property. These details will help greatly when it comes to the design stage.

Once we have an idea of what type of house extension you want, our team will begin designing your new room. During this stage, our staff will offer expert advice at every opportunity as they help you bring your ideas to life.

We only work with material suppliers of excellent quality to ensure that our clients end up with a house extension that has been built to last.
