    • More space for family, hobbies, or quiet time

    • Tailored layout that actually works for your lifestyle

    • Smarter use of your garden or plot

    • Adds long-term value to your home

      Will I Need Planning Permission?

      Not always. In many cases, especially with single-storey rear extensions, you can build under permitted development rights — no formal planning required. The key rules to qualify are:

      • It must not exceed 4 metres in height

      • It must not extend more than 3 metres from the original rear wall

      If your plans go beyond that, don’t worry — we’ll handle the process for you. Our team will assess your home during an on-site visit and let you know exactly what’s possible.
