Customer Feedback

  • Being investors, we chose to build granny flats to increase the overall return of the property. We really loved the modern, stylish finish which was in keeping with the original house. We were so happy with the first granny flat Multidwell built for us, we engaged them to build one in another investment property we have on the Northern Beaches.

    The whole process ran really smoothly and was very easy. We love the finished product and the details of the granny flat are very good. I would highly recommend Multidwell to anyone thinking of building a granny flat.

  • We had ample space in our back yard and needed more rooms to house our grumpy teenager!
    Multidwell had an excellent Display Home at Warriewood Flower Power with friendly, helpful staff and allowed us to view other granny flats during the construction process. We also spoke with a number of their existing clients who confirmed that they were professional and reliable.

    My family and I are highly satisfied with the end product as it well exceeds our initial expectations and would most definitely recommend them to anyone!

  • From our initial meeting, Multidwell have worked tirelessly with us to achieve our goal of building a granny flat on a block that didn’t fall under complying development. Along the way, they have completely managed the process of DA application and have continually sought solutions to issues that arose from council.

    In particular, Paul worked behind the scenes to get us to the end result, continually keeping us updated on progress. Multidwell have made the whole process straightforward and transparent, and have been a pleasure to work with. We would have absolutely no hesitation in recommending them.

  • We looked at about 5 or 6 backyard cabin builders but we kept coming back to the 1st one we saw, Multidwell. Multidwell gives you a modern, contemporary, state of the art building style, with a high quality interior design and finish. We wanted a cabin that we would be happy to live in later on, and the finished interior with excellent kitchen design won hands down over the others. All the builders and tradesmen that worked on the site were always courteous, approachable and always happy to answer questions. Great company, great product and excellent return on investment. We highly recommend Multidwell!

  • If you are considering building a Granny Flat, don’t waste your time looking and comparing one against the other. My advice is go straight to Multidwell, 100% professional in all areas and the quality of the inclusions first class. Paul Mathias Managing Director of Multidwell has carved out a niche for superior designs and workmanship. Thank you Paul for my lovely “granny flat”, which should be renamed superior 1 or 2 bedroom home! One very happy owner of a Multidwell home.
