Rocco Buttliere is building Chicago, one skyscraper at a time, in LEGO. The architecture student has already completed over 30 buildings over the past few years, and isn’t about to stop. Buttliere figured it could take another decade t complete the downtown Chicago area. The buildings are on a 1/650 scale. Curbed interviewed Buttliere about his project.
The biggest challenge is keeping all the models within my uniform scale of 1:650. Any restrictions of working with LEGO tend to go back to the consistency of scale. LEGO pieces are their own modules, meaning one piece can be used at any scale for whatever purpose. It's finding the right piece at my scale for the right purpose that can be restrictive. Starting out on a model, I like to picture a moment or quality of the architectural fabric that would translate nicely into a combination of pieces I am picturing in my head. Sometimes this can take years, as was the case with my Marina City model.
