Five star service *****

“A totally professional and very approachable team who are so easy to deal with. We had numerous meetings until everything we wanted was put down on paper. Would definitely use this firm again.”

—Daniel Davila


Would 100% recommend

“We looked at four different architects because we were unsure of how much XUL had done in the Locals. Other practices were way behind in creativity and presentation. XUL saw things that others didn’t and saw the potential of the house. The turn-around time was also exceptional. If I had to do it all again, they would be my architects.”

—Julliette and Michael Overlander


Fantastic Architecture practice

“They get the balance right between listening to brief, stretching ideas and sticking to budget constraints. I would wholeheartedly recommend. They are a delight to deal with!”

—Rachel Summerfield


A trustworthy and highly creative company

“We experienced XUL as a thoroughly dependable and trustworthy creative team which acted as a supportive partner throughout the project we worked on together. Sebastian got involved in every aspect of the process, and the external consultants he brought in were consistently excellent, contributing greatly to the results achieved. I recommend XUL for any architectural project you may be considering: you will get more than you imagine, including a fulfilling and enjoyable relationship with some deeply committed and creative people.”

—David Templer

Side return extensions have become an exceptionally popular way of extending end of terraced and semi-detached properties. In this guide, we will reveal everything you need to know about these sorts of extensions.

What is a side return extension?

The first thing we need to look at is what a side return extension is. A side return is essentially the narrow strip of land that runs alongside your property. This usually ends up being a dumping ground for outdoor equipment, bikes, and bins. However, savvy homeowners have decided to put this space to better use by extending their property into it. You may think that you are only going to gain a few feet by doing this. Nevertheless, it can make a massive difference when it comes to the layout of your home, giving you much more space to work with and making your living area feel brighter and bigger. This can especially be the case if you have a small property.

Will you need planning permission?

One of the reasons why side return extensions have become so popular is because the rules have been relaxed in this regard. You may not require planning permission if the side return extension is carefully planned. This is why you need an experienced architect on your side to assist. Of course, you can also refer to your local council planning department, and they will let you know what your ‘Permitted Development’ rights are. An architect will understand these regulations and they will know how to fully adhere to them so that you do not end up breaking any rules.

Making your home much lighter with a side extension

Another big benefit of this sort of extension is that it can make your property a lot lighter. You should think about introducing light from above. You can add a series of sky lights if you opt for a single-storey brick extension, and this represents an excellent way of brightening up your home. Another option to think about is the installation of an all-glass roof over the extension. Again, an experienced architect will be able to assist you with this. They will be able to take into account the practicalities too, ensuring you can easily access the windows in order to clean them properly. You also need to consider privacy too, as the last thing you want is overlooking neighbours peering into your home.

An architect can ensure you don’t run into any problems

We have already touched upon the different ways that an architect can help you to ensure your side return extension is a success. There are a number of different potential issues they can navigate to ensure there are not any problems. This includes everything from potential party wall issues to access to the back garden.

Hopefully, you now have a better understanding of what a side return extension is. This is a great way to enhance the space in your home while also boosting the value at the same time.
