Side Home Extensions London
Here at We Love Build, we design and build side home extensions for London homeowners looking to maximise the space that they have. Whether you’re after more space for family life, entertaining, or working from home, a side extension can be a practical and high-impact solution, all without the stress of moving.
Types of side extensions
Every home and household is different, which is why we offer tailored side extension solutions that work with your property’s footprint, your budget, and your goals.
Single storey side extensions
A popular choice for creating larger kitchens, dining areas or living spaces, especially in Victorian or Edwardian terrace homes with unused alleyways. A single-storey extension can make a dramatic difference without major structural disruption.
Double storey side extensions
If you need extra bedrooms, a larger bathroom, or a home office upstairs, a double-storey side extension offers valuable additional space across two levels. These projects require more planning but can significantly increase both living space and property value.
Do I need planning permission for a side extension?
In many cases, side extensions fall under Permitted Development Rights, meaning you may not need full planning permission. However, this depends on the size, location, and type of property, as well as whether it’s in a conservation area or a listed building. Your Local Planning Authority (LPA) will be able to advise you on this, but when you choose to work with us for your side extension in London, we handle the planning permission process on your behalf. One of our experienced experts will check whether or not your plans are covered by Permitted Development rights, and if not, they’ll collate all of the information necessary for a planning permission application.
From here, we will manage the status of your application, while also navigating any building regulations that need to be adhered to with the proposed work. We’ll liaise back and forth with the local authorities, keeping you updated on the status of your application, and once permission has been granted we will map out the timeframe of your project.
Why choose a side extension?
There are plenty of reasons why a side home extension may be the perfect solution for your renovation plans - here's just a few that we have selected to give you an idea of the impact that this type of project can have:
Increasing living space without moving home
Moving house in London can be an expensive, disruptive, and long process. A side extension gives you the space you need without having to change address, schools or commute.
Makes use of unused areas
Many London homes have unused side return spaces, narrow alleys or gaps between properties that serve little purpose. We transform these areas into valuable internal space that flows with your existing home.
Ideal for creating open plan living spaces
A side extension can open up your home, creating light-filled, open-plan kitchens, dining areas, or lounges that better suit modern living. Whether you’re hosting, working, or relaxing, an open-plan layout gives you flexibility and comfort.
What is the average cost of a side extension in London?
Costs for side home extensions in London will vary depending on the size, materials, access, and specification of your project. Here at We Love Build, we operate within your budget, and and we’ll help you to create something that gives you the best value for the investment you’ve made into your home.
How long does it take to complete a side extension?
Timelines depend on the complexity of the build, but typically:
Single-storey side extensions: 10–14 weeks
Double-storey side extensions: 14–20 weeks
We’ll give you a full project schedule before work begins and keep you updated throughout. Our goal is always to minimise disruption and deliver on time.
