Hoi Yat Tsoi MSAI


I am a qualified architect, currently working as an associate for a London-based architectural practice.

As my weekend hobby, I love to discuss design with others in the profession and illustrate for other architects.

During my school years, I illustrated my ideas with watercolour. My abilities to build 3d models and render CGIs have been acquired over the years from work. Nowadays, most of my ‘line & wash’ illustrations are being done with a digital pen tablet, which means my ‘free-hand’ drawings are in fact digital and more flexible.
