EXPAND YOUR HOME WITH A SIDE RETURN EXTENSION
Adding a side extension can drastically increase the space inside your home by essentially bringing the outside, in.
Side return extensions get the most out of the land you already own but don’t use.
Side return extensions—or side infills—add much-needed space and value to your home, maximising outside space that would have otherwise gone unused.
Why waste the space outside your home when you could bring it inside and get a larger ground-floor living space?
We can expand your ground-floor space by building outwards from the side of your home or the back. By adding a side return or rear extension, you can enjoy more of your home now, and add value to it for the future.
Having a bigger ground-floor space—whether it’s a small area taken from the side strip of your house, or an entire floor space added on to the rear of your home—will attract a broader range of buyers and renters who need a bigger living space. This is a huge bonus to have when you put your home on the market—especially in London.
We have delivered a wide range of high-quality side return extensions on time and within budget across London over the past 30 years, and are proud to tell our customers that we have never missed a deadline.
How much is a side return extension in London?

What happens during a side return extension?
When we take on a side return extension, we follow our tried-and-tested process to ensure your project runs smoothly and remains within your fixed budget. Extensions don’t start and end with the physical construction—so we aim to make the entire process as streamlined and efficient for you as possible.
Our safe build process
-
Our side return extension projects remain within the fixed budget we agree on at the start of the process—and never budge.
QUOTES:
There are no upfront costs or setup fees at Safe Home Builders. Once planning permissions and structural drawings are confirmed, we’ll conduct a home visit to assess your space and gather measurements. We’ll then provide you with an initial estimate of costs for the entirety of your side return extension project.If you’re happy with the estimate, we’ll then move to tender. This is where we finalise a more accurate quote that includes a thorough breakdown of costs for the entire project. It’ll be a single, fixed fee that doesn’t budge, so you can have peace of mind that there will be no hidden surprises along the way.
PAYMENT:
You can take care of any final payments up to 6 months after the project is completed.TIMELINES:

We deliver high-quality side return extensions and work safely on the job.
Before getting to work on your side return extension, we’ll take care of the legal and health and safety requirements. This includes validating insurances, contracts, and planning permissions.
TEAM SAFETY:
Now, it’s time to start building! Physical safety will remain a top priority throughout your side return extension project. Our team adheres to strict health and safety protocols, guided by trained experts across first aid, fire safety, and asbestos awareness. And we’re proud to say we’ve not had any accidents on our project sites for over 6 years.STRUCTURAL SAFETY:
We also construct all of our side return extensions to be structurally safe and built to last. This means it’s very unlikely that any of the common problems associated with new side return extensions will crop up in the years ahead.One of the most common issues to be aware of when choosing a contractor for your side return extension is sub-standard brickwork pointing. If work is not completed to a high standard at this stage, problems will arise in the future, and can lead to anything from damp issues to frost damage. This will require repointing in the future, which can be expensive depending on how much of the brickwork needs tending to.
We avoid this by completing all of our side return extension projects to the highest standard. We also take the time to learn exactly what our clients want to get out of their new extension so that we can deliver them a new space that is not only structurally sound for the long term, but also answers to their unique needs—without cutting any corners to get there.

We build all of our side return extensions to a high standard so our customers get an expanded space in their home that’s built to last. We’re confident in the quality and longevity of our builds—and have the guarantees to prove it.
SETTLING:
With any new build, including side return extensions, there’s always a ‘settling in’ period where walls can crack. This happens when the lumber used to build the extension loses its moisture and shrinks. And it’s completely normal.It can take anywhere from 6 months to 3 years (and in some cases, longer) for the structure to completely settle into its foundations. That’s why we offer a 10-year guarantee to cover any structural damage caused by settling. We also provide a 2-year cosmetic guarantee, covering any aesthetic touch-ups such as plastering and painting that can also be affected by settling.
