I'm really confused by the use of the “no” particle when I compare the following two sentences:
That building over there is famous
Achira no biru wa yūmē desu / あちらのビルは有名です
That building over there is tall
Ano biru wa takai desu / あのビルは高いです
Both sentences are pretty much identical in structure. Why would the polite demonstrative require the の particle, but the regular あの demonstrative not?
