Speaking from first hand experience there isn’t a house big enough to hide that thing in. I’ve had plenty of big houses over the years, nothing I’d waste space to store that thing in.
They can handcraft it for me in a week (that sounds completely plausible), and shipping to US costs $220. For a $480,000 table. They are going to entrust a $480,000 table to a $220 overseas shipper. I have this vision in my head of the shippers being the Three Stooges.
