The early flying houses will be in the form of high tech sustainable airships and taking a flying car from them will often be less energy intensive than landing the whole house
Here at the flying house project, we haven't forgotten about the flying car. At this point we've all been waiting for them for so long that when they arrive (in affordable, safe, and mass produced form), it'll be rather anticlimactic. However, latest flying car designs can make us think about the aerodynamic stylishness of flying house architecture in general. The shapes of less realistic far future antigravity cars can come in handy when thinking about the luxury Art Deco/"iPhone of the sky" nature of the house.
Compare the above styles to more realistic flying cars already existing or in the works below. We see that above are much more compatible with luxury airships and Zeppelins of the 21st century.
