Exterior Walls & Weight Question

[Josh24]

I'm currently in the process of building a new home and thought it would be cool to build an aquarium into the cantilever (sp) of the dining room. For those of you who don't know these are the box outs seen on the outside of homes that extend beyond the foundation walls.

My conern is that the tank will be exposed to an exterior wall on the back & sides. Is this something I should be concerned about. Heat in the summer & cold in the winter?

Will the weight of a 6 foot tank cause any problems? I would imagine a portion of the weight would fall directly on the foundation wall while a portion would fall on the i-joists on the outside of the wall.

I'm just looking for some feedback from more experienced reefers then I.

Thanks
