    Our Clients Say

    • After searching millions of others, Perth Granny Flat Specialist seemed to be the one that I could rely on the most.  I got a good rapport with Shane and I knew that if anything went wrong I’d be speaking with him and not some random site manager.  My mum needed some extra assistance and didn’t like living by herself anymore so we decided we’d put a granny flat in the back of our property.  She’s moved in and she loves it.  All through the process had no hiccups, if we did all we had to do was call Shane and say “we found this…” and it was “no problem, all done, sorted”.  We are very very happy, mums happy and over the moon.

    • I ended up going for Perth Granny Flat Specialist because they offered the best service. They were really helpful, really good quality building and that’s what I wanted.  The whole process was really easy, dealing with Shane (who is super lovely) and he explained things really well.  They had good software called BuilderTREND which we could communicate through.  All the tradies that came here and were in my backyard were really wonderful and lovely, didn’t make a mess or work loud.  It took about 3 months and we’re really really happy with the outcome.  It’s a beautiful little house for my parents to move in to and they seem to be really happy and it’s a great quality build.http://perthgrannyflatspecialist.com.au/wp-content/uploads/2017/04/W12.jpg

    •   We looked around at quite a few different companies to see which would be the best.  We had a few quotes and looked at a few companies but then we saw Shane’s advert and decided that was the route we’d like to take.  Our experience has been really really good, Shane and the boys have done a marvelous job. Everything from the planning right the way through to the acceptance and the information that they gave us, they went through every little bit of detail.  It was really really interesting and never at any stage did I have any doubt that it wouldn’t work out properly.

    • We used Shane and his team to do our granny flat extension because we had used him previously for a couple of projects.  We decided to go with him because their whole process has been so easy in the past and we knew that the team he has working for him are great tradesmen and great blokes as well.  They’re really easy going, they’re flexible, they’re very neat and they make the project just so easy.  There were no headaches throughout this, it was just a very easy process and I would definitely recommend them, they were fantastic!

    • Choosing Perth Granny Flat Specialist for the job was our best decision in the whole process.

    • Shane was fantastic to deal with, as were all the trades people he used.  We couldn't be happier and we are so very glad we chose this company to not only build my mums granny flat, but our enormous deck and extra window in our house.  We inquired about building the granny flat with a few of the more well known companies, however we felt we were 'just another customer' and neither listened to what we were requesting, as evidenced by the initial draft plans they presented to us.  It is so much better dealing direct with the builder, rather than a sales rep.  We can't fault the quality craftsmanship and professionalism of this company!  We have no suggestions for improvements as our experience with Perth Granny Flat Specialist has been outstanding!

    • We would like to record our thanks to Shane Williams and his team at Swan River Construction for a very pleasant experience in building our ‘granny flat’ completed on 7th November 2014. The project started with the slab in the third week of August and we moved in on Saturday 8th November. We had spoken to other granny flat specialists in the planning stage but selected Swan River based on being able to deal directly with Shane and his team and their willingness to discuss the project at all stages and to accommodate and deal with any queries. The flexibility on all aspects was not the case in our discussion with other builders. Our experience all along was very pleasant and we are only too willing for Shane to show our cottage to any prospective clients.

    • We chose Swan River Constructions for a small renovation job. After meeting with Shane at our new home prior to moving in we talked through the planned work and decided the quote was very reasonable! They wasted no time in getting the job started, there were no hidden surprises or extra costs involved and the job was done in a quick and timely fashion, perfect for us to move into our new home on time! Shanes professionalism and honesty from the beginning provided us with options when available and a phone call to discuss progress every day, the quality of the work and finished job was outstanding and we’re very happy with how things turned out! Their work is guaranteed and that sets them apart from other companies! Thanks Swan River Constructions.

    • We have been extremely satisfied with Swan River Constructions completing our house extensions. They have been prompt, professional and transparent in all dealings and we will happily seek their assistance again if and when we may require another job done.

    • Shane and his team were absolutely sensational from start to finish and I couldn’t be happier. It was great to be able to go to work knowing I had a reliable, honest, trustworthy, capable team completing the work while I was away. Shane’s advice was always honest while still being mindful of our needs!!

    • We contracted Swan River Constructions to do all of the timberwork on our architecturally designed house in Dalkeith. The finish and attention to detail exceeded all expectations and draws comments from everyone who visits. Having someone on site with great knowledge of the building process, who could deal with the day to day problems which arose, meant that I could put my efforts into the core needs of my business. The work completed was of a high standard and was well planned and supervised. The invoices provided were accurate, detailed and honest. The tradesmen were on time and turned up when they said they would, and worked well. They responded to my requests for some urgent work on several occasions and arranged for specialist tradesmen to complete work. In addition, Shane assisted in a cost effective manner, with design input on some complex issues. I have since nominated Swan River Constructions for substantial work at our Commercial Redevelopment site, as well as for work on some other upcoming developments. In the building business, referral is the highest compliment you can give.

    • The main reason we chose to use Swan River Constructions for our renovation was due to recommendations we received. We were impressed with Shane’s professionalism and how he went about his business. We have found him to be professional, honest, open, upfront and a good communicator at all times. At no time during the duration of our project did we experience any controversy or issues with any tradesmen. Work was completed on time and on budget. The few surprises which popped up were dealt with promptly in an open and transparent manner. We were completely comfortable leaving Shane in charge. We have already recommended Swan River Constructions to friends who are looking for a builder and would definitely use them again.
