well I'd like a decent library.
By 'decent' I do mean the size of an aircraft hanger with motorised shelf platforms and a million book capacity with automated book find and retrieve.
Working on the principle that I'd just buy loads of books so there'd always be fresh stuff on the shelves.
That said, I have about 10,000 e-books on my nook.
At the moment it's great. I just scroll randomly through a folder full of books to pick the next one and have read a lot of different authors and books I'd never previously heard of.
Back to mansions.
So library, games arcade.
Probably just a couple multi-platform game cabinets and a LOT of pinball machines
A good sized fishing lake would be good and a decent woodland area.
But that's more big land than a big house.
The whole huge room thing, just doesn't work well for me.
Unless it's a library or kitchen with all the 'toys'. What's the point ?
Now what I've always wanted to do, is buy an enormous warehouse.
Roof it with a clear roof and a shitload of solar panels and build a country 'estate' inside it.
So you get all the space, programmable weather, free power and a few small houses, but all the storage and specialist areas and rooms you want
Outdoors !
Likewise if i were going to have a luxury boat I'd do a similiar thing. Gut a super tanker and build my park in the hold.
Off road segways all round, for transprt
Plus the tanker would give me a launching ground for my Gibbs technology amphibious vehicles.
A super tanker is also harder for pirates to board, and - obviously - there would be anti-pirate measures - sensor guided electric mini-guns would be favourite.
List of 'rooms' I would like in my warehouse/tanker:
library
walk in salami and cheese curing 'cave'.
A kitchen 'area' complete with every oven type, gadget and toy always available for use.
shed sized smoker
Fully equipped wood working area
fully equipped meat processing area
Rapid prototyping room - complete with metal printers, multimaterial printers and some fdm machines as well.
2 lane Sling range.
Games arcade
Mini-woodland with mycelium infused trees for a varied fungal smorgasbord
'natural' pools and streams with both edible fish and crayfish.
non-sling target range: guns, bows etc.
I reckon 100m x150m, might do it - bit obviously the bigger the better
I think I'm leaning more towards billionaire territory rather than just ordinary multimillionaire capabilities.
But you never know
win a 100million on the euro lottery, and who knows what I could do !
