I'd separate these two roofs with a gutter. Firstly, you have both on the same plane, which is more aesthetically pleasing, and secondly, the water from the greenhouse section will be useful for the plants inside!

No! The exterior wall should be braced at the top with a horizontal beam (header), creating a single frame. Ceiling joists are oversized unless there is a usable attic. These joists should be mounted on a so-called balloon beam, recessed into the load-bearing wall studs, ensuring a very strong ceiling structure. Another option is a platform construction. Note that on the structure above, the ceiling joists, even without the use of spiks or scruws, carry significant loads. The connectors only fasten the structure and are not subject to shear loads at all.

With these pool dimensions, to achieve a weight of 12-14 tons, the pool would need to be approximately 2.5-2.7 meters deep. However, with a standard depth of 1.2-1.5 meters, the load per square meter is 1200-1500 kg. In my opinion, this is too much, unless you hire a structural engineer to design it. Personally, I would place the pool on (or even better, in) the ground and surround it with a terrace. As bellow
