In fact, the practical guiding principles of the Book of Changes are: the unity of opposites between Yin and Yang, the mutual change of ebb and flow, the best balance, extending to people, and advocating rational moderation. The eight most important words of the Yijing geomantic omen are "mountains are surrounded by water, and the wind gathers gas".
Seaside villas can't be "surrounded by mountains and waters, hiding the wind and gathering gas", which is actually not suitable for permanent residence.
In fact, as you can see, villas by the sea are often used for business, such as homestays, such as hotels, and people are constantly changing their lives. It doesn't matter if you live for a short time, but you can't carry it if you live for a long time. If it is a permanent house, we must consider whether the balance of Yin and Yang is stable, and we must not be exposed to the sun during the day (sunny) and attacked by the sea breeze with salty water vapor at night (cloudy). You must "stay around" and not look around. There's not even one to stand in your way.
