Sometimes designers take inspiration directly from nature. One of my favorite architects is Francis Kere, when desiging for his 2017 Serpentine Pavilion for London’s Serpentine Galleries, he drew his inspiration from the palaver tree which also has some cultural significance to many african communities. The tree serves as a meeting point for village matters and ceremonies among other things.
The structure has a wide canopy like roof that is made from timber slats and covered by transparent skin (Cited from The Spaces). The canopy-like roof, just like the palaver tree leaves, provides shade and filters light while protecting organisms and people underneath from rain. The structure also has a steel body with a central void that channels water through an opening, just like the trunk of the palaver tree.
His other design inspired by the palaver tree is that of the Benin National assembly - that has a trunk like structure as well as a canopy like roof as shown below:
There are several other examples of designs by architects that draw their inspriations from surrounding trees and nature and I think that this is something that more and more designers should emulate in addition to actually intergrating nature into the structures.
