I’m writing a fairy-like humanoid race that have the ability of flight through biological/magical means. They are in their equivalent of an early medieval era and are the sole sapient species in their habitat.
Flying for them would use just a little more energy for them than jogging. On average they don't fly for long distances for travel but fly frequently in bursts to get around in everyday life. They feel a biological urge towards flight and it has cultural importance in sports/hunting/dance. Children of the species cannot fly and the ability develops over 2-4 years during puberty. Elderly members gradually lose their ability to fly.
Carrying something heavy during flight would be difficult if not impossible so building structures in high places would be hard without assistive construction equipment.
I am new to world building and don't know a lot about architecture outside of medieval castles and large structures. What would I need to consider when designing a basic residential structure build by this race?
