Cantilever pool for a house

[MonsieurR]

Hi guys,

An architect is doing remodeling for a house on a hill (high seismicity region on sloped soil) and wants to place a cantilever pool (see attachment). Width is ~3.5 m, depth ~2.0 m, length pending.

Considering the house and terrace are already there, meaning this pool would not be monolithic with the rest of the structure, do you see this project reasonably possible?

I'm thinking the main problem is stability and constructibility. I was thinking maybe anchor bolts to the ground (dywidag or similar) may solve the problem but I don't know the practicality of such solution. Another approach would be a big foundation below the pool but my numbers tell me it would need to be huge.

Since the length is pending the most obvious solution would be to choose one with a cantilever that doesn't lead to a stability problem. This seems the obvious thing to do since at first sight the photo seems something not achievable, yet the problem is it deviates from what the architect wants.

Do you have any thoughts on this?

Kind regards.

No interest in my cable stayed approach?

@hokie66, sorry I didn't see your first point. If i interpret your proposal correctly I think what you propose is a possibility, yet that would ruin the view of the terrace with the cables (IMO) and the tower would need to be very tall since the house has 3 stories (I think such hight would not be allowed by the municipality. I just think it would be more complex than a big foundation (which would need to be there anyway)

Yep. I based my wild suggestion on a single storey house.
