There is clearly a relationship between the needs of our bodies and the choices we make in designing architecture. The sizes of rooms, heights of ceilings, pitch and size of stairs, these and many other factors are influenced by the size and shape of humans.
Our bodies are also relatively defenseless against the elements, and so we design our buildings to protect us from heat and cold, from rain and snow. In this we differ from many bird species, who build their nests outdoors because they have evolved to be more comfortable with those elemental forces.
I am trying to imagine alternate species that have advanced civilizations akin to our own (eg: written language, electricity, the use of tools, etc.) but a very different physiogamy. What might their architecture be like?
We might be able to take a tip from other Earth species that build their own homes, such as rabbits, beavers, bees, wasps, birds. In each case, the typical home built by their kind is optimized for the physiological needs of members of their species, as well as their particular social organization.
Could we create a taxonomy of alternate architectures for hypothetical species with advanced civilizations? Even if we assume Earth-like conditions (gravity, rainfall, temperature range, atmospheric pressure, etc), I suspect there would be fascinating variations.
