Your Home Can Grow With the Way You Live

A home can start to feel tight as families, work and everyday routines change. Moving is not always the best answer when the location and much of the existing house still suit you.

A well-planned extension can add a bedroom, living area or a stronger connection to the garden while keeping the parts of the property you already value.

  • Not enough bedrooms or living space
  • A closed layout that limits family use
  • No direct connection to the outdoor area
  • Need for a home office or flexible room
  • An existing home worth improving rather than replacing

    I engaged Built Carpentry & Co to do an extension to my home after some storm damage. I could not be happier with the work Jordan & his team did on my property. Punctual to the minute, the quote was reasonable & accurate. I was made aware of any risks & possible variations to my design, the quality of their work is 5 star. Would highly recommend in fact I have recommended to friends. Honest tradesmen like yours are hard to find

    I couldn't recommend Built Carpentry Co enough to anyone around me and more. Jordan and his team have been supportive, knowledgeable and patient during my renovation. From the moment Jordan came out to consult on the works needing to be done, he has helped me design and bring my vision to life. The workmanship has been impeccable and the attention to detail has been amazing.

    We recently did a renovation and small extension on an old house. It took twice as long as originally advised and was a very unpleasant experience from start to finish. We reached out on our local community page for help with the defects list and found Jordan, we could not be happier. He is knowledgeable, professional and a great person. Jordan and Mitch have made such a positive difference to our journey, we can not thank them enough.
