We are very happy with the work Otto has done for us in the design for townhouses. He is very easy to deal with, open to our suggestions and very happy to listen to our requests and explain why he thinks a particular design is worth doing (or changing). We would never have thought of all the things that will make our townhouses work well. We'd be happy to recommend Otto and Koscad team.

Otto and his team are really easy to work with. Work and drawings delivered in our set time frames and excellent detailed drawings given. Numerous revisions were done and they were happy to do this as they have a real understanding of how important it is for the home builder to get their vision right. Highly recommend. Very professional. Truly happy with our experience.

The extension to my property in Coorparoo was a complex job and I had an idea of a basic concept that would work for our family home. Otto and his team took my concept and developed it into a polished final design that surpassed my expectations with attention to detail that considered all aspects of design even down to incorporating niches to improve natural lighting in some areas. Throughout the build he has provided excellent support and as an owner builder challenged some of the certifiers comments such that the final result will be a truly fantastic outcome. I would not hesitate in recommending Koscad to others or using them again

Otto and his team at KosCAD carried out the architectural work on my Home in Wilston. Otto’s attention to detail was impeccable. Nothing was too much trouble for Otto and I would be happy to recommend him for any architectural work you may require. 


We enjoyed our experience of designing our home with Otto. He listened to our needs,and delivered with additional touches that we had not contemplated. His designs incorporate natural flow of light and ensures the best use of space. He was patient, and willing to give suggestions to enhance the layout of our plans, but made sure that he was working within a set budget. We will definitely recommend him to our friends.

He design work is outstanding, He is always available for communication and dialogue,

All our jobs are have always been completed in a timely manner and his costing is very reasonable.

Koscad provided excellent service as we embarked on our first build project. Otto and the team provided great ideas within our budget that we can say really worked after a great two years living in our Camp Hill home. I've since also engaged Koscad for work at the local kindergarten with pleasing results once again.
