“ We have previously renovated with Addbuild
We are a return customer because of the professionalism and results the first time around. We have really enjoyed having the team back and the quality of the work they do. From Jack, John and Joey getting the lock-up sorted, to Adrian and Pete doing the bits and bobs and some familiar trades from last time along the way, they have produced the result we have been imagining for so long!"
“ Our interactions have exceeded expectations
With Addbuild, we knew from the beginning that we were heard, and that the team would be capable of designing and building our dream home on time and within budget. From our initial conversations with the architect through to those with the carpenter and all the specialist trades, our interactions have exceeded expectations and I can’t recommend Addbuild enough to our friends."
“ We highly recommend the team at Addbuild
We added a master bedroom, ensuite, and walk in robe to our existing two storey home. From the beginning we felt very comfortable with Addbuild's approach. Steve really listened to our brief and provided excellent advice. His final design was outstanding. The management of the design, consent and contract process was seamless and stress-free with clear instructions from the team at Addbuild and very little effort required from us.”
“ I would highly recommend Addbuild
Right from the first contact they were professional and easy to deal with. The designer added a lot of value giving us more functionality and storage plus improved the look /appeal of our addition from the street. The building team were very courteous but most importantly very good. The site was left clean and tidy at the end of each day and rubbish was removed. The job was finished as per the contract price and on time without any defects.”
“ Best thing we've ever done
From day 1 the experience with Addbuild was excellent. From the moment Emery came to our house with his design to Greg our site supervisor, the tradesmen were all excellent and the workmanship was up to standards.The few little issues that we had were always attended to almost immediately, phone calls were always returned and the office staff were always helpful. We have never done anything major like this ever. We were assured that everything was going to be ok. And it was!
