A house extension is an excellent way of adding space, value, and character to your home. Whether you are looking for a small extension or want to completely remodel your home, at DS Squared Architects, we offer a personalised design and planning support service to fit in with your lifestyle and budget.

For most families, even a small extension is a major undertaking, and we understand the importance of the project to you and the impact it will have on your family and your life. At the heart of each of our house extensions is, therefore, a commitment to minimising disruption while maximising your available space and the features you can achieve within your budget.


People invest in a house extension for many reasons, whether they are looking for an additional bedroom, to make space for adult children, accommodate a home office, having a closer connection with your external garden space, or simply as an alternative to moving house.

There is so much you can achieve with a personalised house extension design from DS Squared Architects:

  • Increase the market value of your property
  • Add additional guest bedrooms, bathrooms, and living spaces to your home
  • Create dedicated areas for hobbies, exercise, art, and crafts
  • Build a dedicated home office or study space
  • Remodel your home to make better use of your floor plan or enjoy open plan living
  • Restructure your house to make it easier for people with mobility or health needs
  • Convert your loft, basement, or outbuildings into functional rooms, bedrooms, breakout areas, or social spaces.


Land is expensive for homes in London and families frequently don’t have much space to play with when planning their extension. Through clever use of space, efficiency and attention to details, our contemporary extensions can transform your home so that, even with a small additional floorspace, it will feel bigger and more spacious, feel less cluttered and constrained, and make a more striking statement on your street.


Our bespoke house extension designs help you make full use of the permitted development rules for smaller extensions, and work in sympathy with similar homes in your area so that planning applications are approved quickly and without amendments.

We also recognise that your home is not your neighbour’s home, and that ultimately your extension is about your needs and the needs of your family. This is the reason why no two-house extensions are ever the exact same. 

We design for you, creating your new home extension and layout around the needs of your family, your timescale, and your personal tastes.

Our team will liaise with your local planning authorities to ensure swift approval, confirm that building control compliance is secured and supervise the process closely to ensure that all work is signed off and completed to the highest standard.


Big or small, we are there for you. Planning a house extension is an exciting opportunity to transform your home into something deeply personal and meaningful – while adding thousands to its market value. To find out more about the possibilities for your home, please give us a call to chat with one of our Chartered Architects today. We can discuss your ideas and provide a free quotation and talk more about the process of designing an extension, pursuing a planning application, and managing your build.
