Lok Jansen is an architect and illustrator based in Tokyo. Jansen did his Masters in Architecture at the Tokyo Institute of Technology. After doing a lot of concept designs and presentation drawings, he has since switched to doing illustrations.

There is something about the amazing and unique three dimensional space and complex structures of Tokyo that has an impact on artists. Jansen’s response, as both an architect an illustrator, has been multi-fold. His site, which he named Imagineering, features photos, sketches, visual essays on architecture and illustrations. The illustrations show a fascination with the city as complex architectural and sculptural forms, textured with mechanical structures like bark on a tree.

Jansen describes: “The metropolis to me, is like an organism. Growing. The tech seems almost organic. Highways, train lines, fly-overs, aircons, ducts, wires - they’re so wild its almost like greenery.” Through the flowy lines of Lok Jansen, the city do appear to take on a life of its own.

Jansen’s shares many of his latest sketches in this ConceptArt forum thread.
