I made a sketch model at the smallest possible scale. Being happy with that, I made another at four times that scale. The larger the scale, the more detail we can add, and the easier it is to adjust proportions, and so the closer we get to the real thing. At each stage, the model can answer more questions about the final product.
I put this together without much thought to natural light:
So, I started over, and let the light in:
Ten double-cube modules stacked in rows of 4, 3, 2, 1 modules:
Instead of treating the model as a sculpture, I took seriously the functions and locations of the building’s spaces. Walking from the front (on the right) to the back, you encounter the entrance, a 20′ x 40′ receiving area, a hallway connecting to a row of 10′ x 10′ examination rooms, a nurse’s station, and a hall leading to a row of 10′ x 15′ rooms for short-term admissions. The second floor is for administration.
I generally start a model by laying out the plan with plates. Then I mark the corners of the plan, as seen below. Next, I lift out the plates and start building directly on the big base plate. Using one or more plates to define room sizes guarantees that ceilings and roofs will fit, using the same plates.
