One thing that I could not help but to notice in this link: http://titanic.pagesperso-orange.fr/page58.htm was that there is a picture of what looks to be a Dome that was a part of the GSC.
I think that is of Britannic's wreck, not Titanic's. Britannic had more of a flat dome, quite like Aquitanias, if you have seen her staircase. Since Britannic had entered service as a Hospital Ship, her interiors were very plain, simple and had exposed pipes and so on.
The grand staircase in my opinion was the most beautiful ship, the Crystal Dome was wonderful passengers could see the light of day. This was the first class staircase between the first and second fireplace. The other was near the aft staircase. Passengers could also get one of the three elevators to get to the dining room, the staircase going up to the upper deck because the deck F deck was 6. The edge made of bronze should be spectacular.

Too bad they don't make ship atriums like they used to, i.e. grand staircase-style... While those grand lobbies in today's massive cruise ships overshadow the ones in Olympic-class liners, with multilevel voids, glass elevators, and a beautiful fountain for instance, they seem to lack the allure of the intricately-designed Titanic staircase... Anyway, let pictures speak for themselves and here are two for your viewing pleasure!
