As you can see, a lot of variables. The building code has changed a lot since the original was built, too-both with regard to strength and to child safety, so that increased cost about 100% over old-railings.
However, Europe and Asia are two different socio-political continents, ie, they are divided like that because the people who lived there have decided it to be that way. So in one way, it is one continent, and in another way, it is two.t's like comparing a banana to a head of lettuce, too different. The landmass of Europe and Asia does have a name, however: Eurasia. However, Eurasia is also joined to the continent of Africa (more specifically, Asia to Africa).
Europe and Asia were separate plates (mostly Baltica and Siberia paleo-continents), just like India is a separate plate today, but fused together in the formation of Pangaea.The Ural mountains are very ancient and worn down, but the Caucusus are higher and younger. plate is different than a continent, though, and part of the North American plate in eastern Siberia is in Asia. Should this be a separate continent? Asia includes other plates as well, including the Iranian and Arabian plates. Indeed, India and Australia are on the same plate, but completely separate continents.
