Sorry had to :^D.
It appears that they are hand made and only a few each year. What I read from their page, it seems like you order directly from them.
Installation & Ordering
Only a few of these extraordinary tables are produced each year, being hand crafted in the finest British traditions of furniture making. Each table is truly a one off item, a museum piece of the future, the price for each is dependent on the materials and cost of the construction, which is generally in the tens-of-thousands of pounds.
The installation of this large piece of furniture must also be considered, as it is composed of a number of pieces and has a total weight of about 220 kilos (485 lbs). We can deliver anywhere in the world in a single shipment and then an installation technician, from the UK, completes the assembly on site.
We have no overseas agents, showrooms or installers, nor do we currently seek any.
It appears there's no option of 'self installation', I'm guessing it costs $15k.
