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!

Allambie Heights

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.

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.

It was a pleasure working with Paul over the course of our 2 Bedroom Granny Flat build. He is more than helpful and accommodating, friendly and willing to get the job done. The word ‘Granny Flat’ does not do justice to the look and quality of the build so we have named ours the ‘Studio’. Thanks to the Multidwell Team for a job well done!

Frenchs Forest

We were very impressed. We found Paul to be professional, reliable, and helpful. He kept us informed at all times, and always ensured the work area was clean and tidy. The challenge of our two dogs being able to have the freedom of the back yard, but without escaping or interfering with the work, was handled without issue. And finally, we are all absolutely delighted with the finished product.

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!

Brett and Sue

We discovered Multidwell at their Display Home in Warriewood and were impressed by what we saw. Paul met us at our house soon after and very quickly set about designing the perfect unit for our property. His design ideas were inspired; they then delivered a beautifully finished unit ahead of schedule. We had no trouble renting it for top dollar and this really relieved the pressure of our high mortgage. Our granny flat delivered an outstanding investment result.

The entire process was managed with consummate professionalism; quite simply Multidwell took care of everything and eliminated all the usual stresses of planning, approval, construction and final certification.

If you want a high quality granny flat with beautiful finishes and outstanding workmanship, you shouldn’t contact any other company.
