This extension project is in Mount Waverley, our customer Zoe and her family members are all piano teachers, she found us from her student's parent and requested a face-to-face quote. Our designer gave a detailed solution which helped her to make the final decision. We made full use of the original bricks deck as the extension room foundation and add a new brick deck, which greatly reduced the cost of the extension, add three-room spaces which totally satisfied their need. The only construction difficulty was the connection with the original house ceiling, we also handled it very well. Now, the whole family members all enjoy the spacious teaching room separately.
