Design King Company is Architectural Design Studio based in Paddington, Sydney. With over 20 years of experience the practice continues to be committed to the founding principle of providing design excellence across all projects. This working philosophy can be seen in projects that range from a tiny artist’s studio in the Blue Mountains to a boutique hotel in Yamba. Although our focus is on design and original thinking, our creativity is underpinned by sound technique, methodology and practice. This level of commitment to the entire building process has resulted in our work being widely published and has been awarded many times by the industry bodies. We have over the years also developed a very keen awareness of our client’s needs and expectations and judge our success by our client’s satisfaction, something we are justifiably proud of.
