Home extensions are both practical and profitable solutions for London homeowners.
Building an effective extension can add to the functionality of your house, increase your square footage and thereby add value to your property market price. A well-designed extension can create a completely fresh feel to your home, or enhance your home’s existing character and design.
A fast-paced London family lifestyle can leave you with little precious spare time.
Moving home can take months and require up-rooting your life, whilst a bespoke extension project executed by The Ratio will work around you and your family to provide minimal disruption.
At The Ratio, we will try to help you to adhere to the specific limitations of permitted development for your extension project. Within certain confinements for some projects, it may be possible to bypass the lengthy process of applying for planning permission. The process could therefore be done far quicker and be more financially feasible than you may anticipate.
A home extension could help you to achieve that cohesive open-plan living and dining space you have always envisioned, bring your child’s dream play room to life, or even create vital storage space.
Rather than moving into a new home, create a new space designed bespokely to your exact needs to accommodate you and your family.
Whatever you envision, our in-house design team will work with you every step of the way to bring it to life. We will consider your needs in regards to space, functionality, budget and timeline. You will be assigned a project manager and on-site foreman who will inform you of our progress and plans during every step of the process.
With our 20+ years experience in undertaking comprehensive home extension projects in the London area, you can trust in our expertise and exceptional standards of construction and finish to transform your home and lives for the better.
In 2019, the government overhauled planning permission laws, meaning many house extensions now fall under permitted development rights. Without the lengthy process of obtaining planning permission, we could have your extension project completed much sooner than you might expect!
The Ratio provides you with a customised service. Our teams build one or more rooms outside the house as part of our single-story extensions. This type of extension adds more space and improves the flow of the house. In this case, the floor plan is enhanced but not totally changed. You can stay assured that our single-story extensions improve the functionality of the space.
A double-storey extension allows you to add a second bedroom upstairs and make space for an additional room downstairs. The downstairs area can be used to build a pretty sizable kitchen and an additional bathroom. What’s more, you can build a dining room or living area with bi-fold doors leading into your garden.
A side return extension is typically built in the kitchen at the back of the house. The side return – the pathway that runs alongside the ground floor of your home – is the ideal spot for the extension. Adding a side return extension to a terraced or semi-detached house is one of the best ways to increase and improve the quality of living areas.
Key Points:
Kitchen Extensions are one of the best ways to transform a cramped and awkward space into a space that the entire family can use. Modern kitchens are more than just places to cook, it’s the heart of the home, it is where you live, eat, socialise, study, and even play. They also don’t require you to give up much of your garden space to build a room that meets all of your needs.
Key points:
They combine a side return and a rear extension to create an L-shape at the back of your house. They are usually ideal for Victorian terraced homes, but they can also be used for modern homes if there is enough space. Wraparound extensions are great for expanding your living space and creating large open-plan layouts. As well as opening up your kitchen area to make place for extra rooms and enhancing the connection to your yard.
Key Points:
A dormer loft conversion is the process of converting a box-shaped structure to a pitched roof. Dormers are extensions that extend upwards and outwards to provide additional headspace and floor space. Dormer extensions typically come with your permitted development rights, so you may be able to avoid the need for a full planning application. Not only that, but these loft conversions are a cost-effective method to add a full extra floor of room.

"Best quality builds in London by far, professional service, I recommend them for anyone looking to fit a new bathroom or kitchen."
Building extensions in London can take 10-12 weeks to complete on average, but this depends on some factors, the primary one being the size of the building as well as the project specifications – occasionally, a large build can take longer.
We cannot give you an accurate answer here as the size and style of the extension, the amount of glazing (both in the walls and the roof) – and the type of roof used are all factors that affect the cost of a house extension.
This depends on the size and the extension. According to Nationwide research on the value of extensions – if an extension was added to an average three-bedroom house, it would add up to 23% to the value of the house.
The short answer is that you do not require planning permission for an extension.
The majority of the restrictions that do not fall under permitted development are to work in front of a house, across a road, or near a boundary.
You are always welcome to visit the site while we are working, as we value your input and approval at every phase. This motivates us to do our best and improve the quality of our work.
If you already have an extension, you may notice that your roof has started to age, reducing its thermal efficiency. You can have your extension roof changed, but first, you need to have the structure of your extension checked to ensure it is strong enough to support a new roof.
The amazing part about extension roofs is that you can usually see the wear and tear that will tell you when it is time to change your roof. Tiled roofs typically outlast glass roofs due to their low maintenance and lack of exposed structure. However, if proper care is taken for them, they both have a lengthy lifespan, with the average being more than 20 years.
