House Extensions in London

Expanding your home with a house extension is a smart way to gain more space while adding value to your property. As moving costs continue to rise, many London homeowners are opting to improve their current homes instead of relocating.

House extensions are ideal for creating spacious, family-friendly living areas. Whether you're looking to add an open-plan kitchen or extra living space, extensions can transform your home to better suit modern living needs. As renowned architect George Clarke often says, "The way houses were built years ago doesn’t fit our lifestyle today."

In the 21st century, homes need to be multi-functional, serving as places to live, work, relax, and entertain. Open-plan living spaces have become increasingly popular because they allow families to spend time together while offering flexible spaces for different activities. This type of layout is perfect for hosting guests, family time, and even setting up a workspace when needed.

If you're considering expanding your home with a house extension, read on to discover some common extension ideas.

Types of House Extensions

Single-Storey Extensions

A single-storey extension is one of the most cost-effective ways to add space to your home. You can extend at the rear or the side of your property to create an open-plan kitchen or a new family room. Single-storey extensions are ideal for connecting indoor living spaces with your garden, making your home feel larger and more integrated with the outdoor environment.

Side Return Extensions

A side-return extension utilizes the alleyway or side space of your property. This is a great option for terraced houses in London, where lateral space can be used to create a larger, more functional kitchen or dining area. Despite being smaller, side return extensions can dramatically improve the flow and usability of your home's layout.

Rear Extensions

Rear extensions are a fantastic choice for creating open-plan living areas. This type of extension typically adds space at the back of the house and can be designed to accommodate a kitchen, dining, and lounge area. With bi-fold or sliding doors, a rear extension seamlessly connects your home to the garden, bringing the outdoors in and flooding your living area with natural light.

Wrap-Around Extensions

If you're looking to maximize your space, a wrap-around extension is a combination of both a side-return and a rear extension. This option provides the most room for expanding your living space and allows for flexible design solutions such as creating larger kitchens, additional living spaces, utility rooms, and even downstairs bathrooms.

Cost of House Extensions in London

The cost of a house extension in London depends on the type of extension you choose. On average, single-storey extensions can start at around £35,000 for a side return and can go upwards of £55,000 or more for larger, more complex projects like wrap-around extensions. Rear extensions typically cost between £40,000 and £50,000, making them an ideal solution for those seeking to create large, open-plan spaces.

Roof Options for House Extensions

Flat Roof

A flat roof is a popular choice for modern extensions and tends to be more cost-effective than a pitched roof. Flat roofs offer a sleek, contemporary look and are easier to install skylights or light wells for additional natural light. However, flat roofs may require more maintenance over time and are generally less energy efficient.

Pitched Roof

Pitched roofs provide higher ceilings and blend well with the architectural style of many traditional London homes. They are often favored by planning departments and are more durable than flat roofs. However, they tend to be more expensive and take longer to build.
