Some 90% of humankind lives within 10 miles of the ocean. Historically, that's because only sea-ports gave one access to the world market, and those living further inland had to be content with what goods could be hauled by wagon. Now that trains and trucks exist, people still prefer living by the sea because the beach is fun, and there's a near guaranteed supply of water in the form of rain. (One would be unwise to try to drink the ocean. Too saline.) Another 9% lives near rivers for similar reasons.
However, there's an obvious downside to living near water: storms. Some forms of weather can raise the levels of water until it's quite inconvinient to the nearby humans. The water gets in your house and promptly ruins everything it touches, usually because mud and/or pollution come with it.
Looking at houses, they look rather water-tight. There are no obvious gaps in construction, and you can spray the average American home with a hose without anyone inside noticing. This is deceptive. Water changes shape to fit its container, and so tiny gaps in nail holes, cracks made by mechanical stress or termites, provide just enough space for water to sneak inside. However, the primary defense that American homes have against floods is basically being built on each a little tiny hill, which slopes down to the street, encouraging water to flow down the street instead. Past that, nothing really.
I can engineer a waterproof house. It would have certain disadvantages. One could not open the windows, and it would get dangerously stuffy inside, as it would breathe only from the attic. However, it would also not be ruined by hurricanes, flash floods (as occurs near rivers during heavy rain), or other storms. Occupants could wait out even the worst storm in reasonable comfort. (Warning, electrical power, phone service, and internet service not guaranteed.)
I would do it by sealing things, as is done in bathroom construction. A plastic or rubber gasket would surround the entire house, extending into the windows, which fit on with a watertight flange, and are sealed with a thick layer of calk. There would be zero space for water to enter, and therefore, even in the worst flood, the interior would stay dry. The windows would have to be rated for significant pressure, lest they rupture during a hurricane (high speed winds and pressure differential outside and inside), or a major flash flood (water is heavier than air, again resulting in a really big pressure differential). Also, for breathability, I would make the house tall. At least two, and probably three stories. Let's go with 3. Only the 3rd story's windows open, and that's where your house gets fresh air from. A venting system circulates it to the lower floors. (The regions most at risk of flooding tend not to have earthquakes. Usually.) A decorative siding would be pasted onto the seal to give this house the look of a home (and not an avant garde scupture.)
