>>2210463>>2210731>>2210737>>2211294I tried looking for construction materials used in Nemo's garden project but couldn't find anything. It is 8m below the water for reference.
Oceanarium walkways with 3m wide curved windows use 12cm thick acrylic.
https://materialdistrict.com/article/blue-planet-aquarium/here is a video showing how they make very thick acrylic aquarium windows, also taking into account optical distortion in the construction technique.
https://www.youtube.com/watch?v=FrPLKMmfGg4This is how to bend acrylic sheets to form curved surfaces. Basically the sheets are heated in an oven and then draped over a mould surface and allowed to cool.

acrylic 10x stronger than glass
uv resistant
polycarbonate 100x stronger than glass
not uv resistant (needs coating if exposed to alot of uv)
layering and bonding acrylic or polycarbonate sheets could in principle work for making quite large windows in a submersive structure.
>>2216360>is it possible for an amateurthat is a very good question, it is probably best to think of a small scale version (maybe one metre wide) and calculate the largest platform possible at that scale. Then work up from there.
Companies like these make large scale pipes in polymer plastics

https://www.nucorskyline.com/globalnav/products/pipe/large-diameter-pipei wonder how much pressure large plastic pipes could withstand at various depths?
the pic is a proposed project called Gyre by a company called Zigloo, the column would be 400m deep. Ship docks at the surface etc, featured in this video

https://www.youtube.com/watch?v=bM6jFokRoZkat around 18 - 19mins in you see it in 60ft waves.
an 80ft wave 3/4 submerged the upper platform and it still survived.
