My husband and I have had the honour of working with KAS Built on a number of our investment properties along with our family home. The quality of their work and attention to detail along with their service and delivery capabilities are what sets them apart. Kosta and his team provided excellent service through the entire process and we could not be happier.

We purchased our first investment property which was un renovated and had never embarked on a renovation project before but saw potential in the apartment. KAS Built were referred to us from family friends who were very pleased with their work. They completed the renovation for us which including designing and installing a new kitchen, wardrobes, laundry cupboards, bathroom vanities and storage units. During both the design and installation processes our requirements were listened to and at times and the team were able to suggest better alternatives to reduce costs and their input was greatly appreciated. Overall, we are very happy with the new look of our investment apartment which saw an increase in the rent we were initially quoted by the agent. We will definitely refer KAS Built to our family and friends.

When it comes to design elements and creative flair, the team at KAS Built proved to have an extensive knowledge of design and space and they delivered well above our standards. They communicated with us through the entire process and were extremely efficient, prompt and reliable. Kosta and his team were meticulous every step of the way from their design approach to final handover and exceeded all expectations. We could not be happier with their work and the dedication to their workmanship.


I engaged Kosta to do a home improvement on my two-bedroom apartment in Maroubra to prepare it for sale. Kosta and his team at KAS Built managed all my joinery requirements and assisted with material and colour choices and on his advice,  I changed the layout to better suit the space. The work was impeccable and my investment property was completely transformed which resulted in a sales price I was not expecting to be able to achieve.

KAS Built assisted design all the internal aspects of our home, better than the plans the architect provided. Their attention to detail and knowledge of space is exemplary. We worked closely with Kosta who provided sound advice, was extremely creative and is very talented. His approach was nothing but professional. KAS Built designed, manufactured and installed a 12-metre long kitchen with island bench, laundry cupboards and storage, built in wardrobes, joinery to complete two bathrooms, a window seat for our main bedroom, outdoor deck with overhead roof, cubby house for our daughter. We have since engaged the team to design and help with the construction of a granny flat at the back of my property that we are seeking a DA for through the local council. KAS Built transformed our house to a home and we could not be happier with the work.
