Awww, that's... uh... sweet, WT
but I'm afraid you're not my type of tiger.
I should clarify, too -- I didn't mean the question as a sort of "if you won the lottery..." question (I agree I'd build a small but architecturally elegant and self-sustaining house out in the Olympia region -- for one thing, I wouldn't want to clean a mansion =P), but rather just as a question about what, in your wildest dreams, would make the coolest and most luxurious absurdly big luxury home/castle. My tastes in this have a lot in common with Stormbringer's... the two-level library is a must, as is the conservatory, and I would add outdoor aviaries and greenhouses, plus full-on wiring for the interior, polished granite countertops in a big kitchen with stainless steel appliances and wrought-iron fixtures... I could go on.
So, let me rephrase:
Suppose a man was going to pay you two million dollars to build a house. You have an unlimited budget (access to his gargantuan accounts), and he wants it to be your idea of perfection in every way, with every amenity and every element you could possibly need to entertain yourself and any guests you would like to have around you. You have an unlimited budget, but the budget goes toward the house and in the end you get your two million and that's it. What do you build, and what features does it have? In as much or as little detail as you want.
