Architecture is often presented in plan — the horizontal cut through a building — but the section (vertical cut) reveals what plan cannot: how spaces stack, how…

Biophilic design incorporates natural elements — light, plants, water, natural materials, views of nature — into built environments. The hypothesis: humans evol…
