Oh, it would be one hell of a miracle. When I was a kid, I used to design my own… well, superhero lairs. I mean floorplans containing everything I could think of that I’d want. Huge garages, laboratories, libraries, observatories, secret passages, gymnasia, theaters. Kinda like those myriad cutaways of the Baxter Building (home of the Fantastic Four) they used to periodically publish:
…except mine were always just floorplans, not isometric cutaways, since I never could draw worth a damn.
In a somewhat more realistic situation (but only somewhat), I’ve always wanted Bag End. The coziness! The pantries! All those rooms and pegs for visitors! The bucolic setting! I could do without the circular doorways and passages (I’m 6’2", and at a scale where I wouldn’t be constantly clobbering my head, the wasted space would be excessive), but I dearly love a well-furnished hobbit hole.
But anyway, I really like my current house, and intend to die before I ever move again. In fact, I have instructed my heirs (currently 11 and 9 years of age) that upon my lamentable demise, I would like all my useful organs donated to worthy recipients, then my skeleton denuded and cleaned of all fleshy bits, then varnished and carefully wired together in a fully poseable fashion, so I can be kept on the ledge above our staircase, gazing out the westward window to the distant mountains. This guy’s holding my place for me:
Also, they can bring me downstairs for Halloween and other special occasions. I’m not above holding hats and coats as well. My kids, bless 'em, are fully on-board. My wife, a bit less so, so I’m just gonna have to outlive her.
Anyway, I do want to make some additions to the manse once my ship rolls in. An addition to the side of the garage will hold all my band gear, amps, guitars, and a wee recording studio. I want a pool and (especially) a hot tub. I want a dumbwaiter, and a couple secret passages. I want more library space. I wouldn’t say no to a sauna outside next to the pool. I’d like an upgraded home theater situation. I’d like a lift inside the garage, so I never have to crawl underneath a car again. I’d like a woodshop, maybe behind the garage. I’d love a sizable tree house atop the avocado tree in our backyard, accessible from my bedroom window via zipline. I need a widow’s walk and a goddamned crow’s nest up top. A small family cemetery in the front yard, even if it’s entirely unoccupied. (Too many of my family were cremated, or are planning cremation.)
Oh, and a hidden underground bunker. With a secret back door. Because.
