Amongst the cities across the globe, Dubai is well known for its tallest buildings. The skyline of Dubai is incredible. The sky is lined with skyscraper after skyscraper, making for some magnificent views if you visit one of these building’s top floors.
Should it be buildings’ instead?
Thanks.

Grammatically, your observation is correct because one of is followed by plural nouns, and the plural word buildings is to be made possessive.
Syntactically, what @Torsten suggests reads better. (You are often copying sentences from newspapers and reports and raising questions of grammar (particularly punctuations) rather than of syntax or semantics, though!)
