I would be happy as a clam if I just had my existing tin can [ok, mebbe a double-wide] situated high atop a cliff overlooking pacific beach, Wa. I saw one identical to my tin can there, alas it was on indian land. the view was tremendous. it would have solar collectors, passive rainwater collection via rooftop and fog mesh collection, a tromba wall for passive heat, a rooftop [enclosed] observatory for both horizontal and vertical viewing [scenic and celestial] with a powerful binocular refractor telescope up there. there'd also be wind turbans as there is a LOT of wind there!
now if I were to go really way out there, i'd build a mansion up there, sub-divide it into spacious apartments/condos, each with staggered concrete/gap isolation between them so no sound or vibration transmission would occur between units. 10' ceilings. i would do this so as many of the rest of my WP brethren could live there if they chose, free. as for myself and my own space, I would have a media room with orthopedically correct furniture, hidden high-fidelity speakers all around, ceiling and walls, surround sound, a restored Conn 653 theatre organ would be the centerpiece. a wall-sized tv set on one end. the color scheme would switch with different lighting against a snow-white backdrop, furniture would be upholstered with color-reflecting fabric. the carpeting would be 1" thick pile. there would be another room which would serve as the bathroom but it would have quasi-classic greek architecture with marble surfaces, a multipoint shower in a large space, recirculating fountains, orthopedically correct furniture. the bedroom would feature 2" thick pile that I could lie upon if I wished. the bed would be California-King, under a golden pyramid, alternating/mixed white/pink/brown noise generators in multiple channels would make the room awash in a fake ocean sound. prismatic colored lights would project all around, 'round and 'round. everything would be jet-black. the garage would hold 7 cars, one for every day of the week. in my auto collection would be a 1972 Citroen DS, a 1988 Cadillac sedan deville, a convertible VW Karmann-Ghia, latest model Honda CRV, 1980 AMC Pacer DL, a honda helix scooter and a heavily modified recumbent Fatbike. there would be plenty of covered guest parking, all covered. the garage would be air-conditioned. there would be a greenbelt on three [non-seaward] sides with hidden entrance. the front grounds would be in a quasi-Japanese garden arrangement.
