Side Extension London – Professional and Trusted Side Extension Company London Offering Excellent Services from Start to Finish. Side Extensions are increasingly getting popular and have become a much sought-after option to increase the livable area. Due to their simple design, small-scale work and quick turnaround, most British homes prefer side extensions to meet the growing space needs of families. This home extension makes the kitchen more functional, enlarges the living room, and even makes adding a new room easy. With KC Builds Constructions, the leading side extension company in London, stay assured that your extension will be done perfectly and exceed your expectations.

What is Side Extension – Side Extension is a type of home extension where the unused space on the side of the property is extended to create more liveable space. So, if you don’t want to use your garden area and the land on the sides of the property is free to use, extending to the side is a great option. The team at KC Builds work with you to bring out a design that resonates with your needs, requirements, and preferences. Also, adding immense value to your home.

We are the best side extension company in London, UK offering bespoke designs, full customer satisfaction and high-quality building work. The team at KC Builds is well expert and experienced in handling projects of all sizes, small or large. We have delivered countless successful side extension projects which is evidenced by the fact that our major work comes from word of mouth. Considering a side extension for your London Home? Contact us today.

  •  Terraced Houses: The experts at our side extension company are well-skilled at adding a side extension to terraced houses. Even if the house already has a rear extension, we have the perfect skill and knowledge to extend the home again to the side or perform an infill extension.
  • Semi-Detached Houses: For your London semi-detached houses, get them extended to the side by hiring KC Builds as your side extension contractors. It is preferred to add the extension to the non-attached side. This will ensure minimal impact of the new extension on the neighbours.
  • Detached Houses: You get the most option to extend if you’re living in a detached house as it is surrounded by land on both sides. KC Builds professional acumen ensures maximum space utilization and enables you to get a space of your choice.
  • Listed Building Houses: Adding a side extension to a listed building is always a challenge. With a diverse experience of more than a decade, we have the capacity and ability to handle all the issues and other challenges with ease.

The cost of a home extension depends on the size, design, and materials used. On average, prices can vary widely, but we can provide a personalized quote based on your project. Contact us today to discuss your plans and get a free estimate. 


The timeline depends on the size and complexity of the extension, as well as any planning permissions required. Most projects take several weeks to a few months. Reach out to our team to get a clear schedule tailored to your home.


Many small extensions fall under “permitted development,” but larger or more complex projects usually require planning permission. We can guide you through the process and ensure your extension meets all local regulations.
