After studying carpentry at Swinburne Technical College, Peter began his career on the tools, shaping his understanding of materials, detailing, and the physical process of building from the ground up. He went on to obtain his residential and commercial builder’s licences, founding Kostas Constructions and delivering a diverse portfolio of large-scale residential projects across Melbourne.

He has witnessed, and anticipated, the shifts in Melbourne’s architectural landscape over the decades, ensuring that the company remains not only relevant but an industry leader. His philosophy is simple: embrace change, without ever compromising craft.
Today, as Director of KC, Peter remains hands-on. He oversees every project with precision, applying the same attention to detail and technical fluency that has shaped the company’s identity since its earliest days. His focus is on building strong relationships with architects and clients who share a passion for well-considered design and uncompromising execution.
It’s this quiet dedication, to people, to process and to excellence, that continues to define Peter’s legacy and guide the KC team forward.
