Types of House Extensions
Rear Extensions
Ideal for terraced and semi-detached houses with garden space that want to add more light and open-plan living space.
​
Rear extensions are one of the most popular ways to expand London homes. These extensions typically extend out from the back of the property into the garden and are often used to enlarge kitchen and dining areas. For properties in boroughs like Islington, where space is limited, rear extensions offer a cost-effective way to enhance living areas without needing to relocate.
Side Return Extensions
Ideal for terraced and semi-detached houses with narrow, underused side passages, that don't want to extend into the garden.
A side return extension is perfect for homes with unused alleyways or spaces along the side of the property. In London, especially in areas like Hackney, many properties are terraced or semi-detached, making a side return extension a practical solution to expand ground floor spaces, such as kitchens and dining rooms, without encroaching on garden space.
Wraparound Extensions
Ideal for properties where more space is available.
A wraparound extension combines both a rear extension and a side return extension, providing a substantial increase in living space. This type of extension is often seen in more spacious areas of London. A wraparound extension can dramatically change the layout of your home, providing flexibility for modern living with plenty of natural light and additional space.
Double-Storey Extensions
Ideal for properties where more space is available and significant additional living space is nedeed.
For homeowners who need significant additional living space, double-storey extensions provide an excellent solution. A double-storey extension can add multiple rooms across two floors, such as bathrooms, bedrooms, home offices, and more. They are perfect for growing families.

Kings Cross Rear Extension and Basement
These lovely clients wanted to create a playroom for their growing children and connect their ground floor to the garden with a rear extension. Living in a conservation area and with listed building status, their options were limited but that didn't stop us. The solution was to extend the existing basement beneath the garden and create a modest and sensitive rear extension that would stream light into the house.
Hackney House Extension and Refurbishment
Another project for international architects is Viewport Studio. An old and neglected house in Bethnal Green was given a fresh new look and a zinc-clad rear extension. The build included flush frameless doors, a large frameless skylight, underfloor heating throughout, and a minimalist modern staircase. Landscaping and ebony decking in the garden provided the final touches.

Would not hesitate to use Canyon again. Work completed on time, on budget, to high spec. But most importantly, for having someone on-site in your home for such a long period of time they made it feel unobtrusive and just easy. Great guys!

Really professional service and went the extra mile to ensure they did a great job. We’re able to work with all my plans but also added their own expertise to improve the design. Highly recommend.
