I engaged Klaus to do a large renovation of our daughters apartment in Woollahra. I live in Brisbane and due to distance I needed a contractor I could trust to do a quality job on time and to our budget. I am glad to say Klaus exceeded all our expectations, he takes a lot of pride in the quality of his workmanship, is very easy to deal with , completed the renovation on time and to budget and has been very prompt in returning to the site to fix a few small defects.

I would have no hesitation in recommending Klaus to future clients.

After completing many projects over the years to find a builder who is prompt, efficient and has a very high standard of workmanship made my project run very smoothly and with limited stress. Klaus follows through on everything he say's he is going to do, he always kept me informed and took great care to explain everything so no unexpected surprises arose.

Klaus has a great skill at coordinating and recommending other trades to keep the project flowing on. I was very happy and have no hesitation in recommending him and have done so to friends. I wish all the best to him in his business. He is a very sincere and genuine person.  I wish dealing with all trades people was as easy and stress free experience.

Aktive Building have been working on a development project for me and their service has been exceptional. Not only have they delivered on the components they were responsible for, they have also helped support deliverables in other areas of the construction that were not part of their delivery.

The level of workmanship and quality is exceptional. No corners are cut and you can always feel comfortable that the builder is doing the right thing by you.The service is friendly, open and honest. If there is an issue that needs to be addressed, it is put on the table so that it can be worked through. I would highly recommend Aktive Building to any person who needs a builder they can count on to deliver the job right.

Having recently completed stage 1 of our renovation we can't wait to start stage 2. Klaus and his team at Aktive Building are professional, helpful and incredibly hardworking. Klaus made sure that everything was finished to a very high standard and nothing was ever a problem. All his tradesmen were also highly professional and efficient and everyone worked well together. The project was completed ahead of time and Klaus kept us up to date with weekly reports and detailed accounts. We can highly recommend Aktive building and cannot wait to work with Klaus and his team on the next stage of our renovation.
