THE WIND FROM NOWHERE: Pyramid First Floor

Some concept art from J.G. Ballard’s little known first novel THE WIND FROM NOWHERE. 
Global hurricane strength winds blast and scour the earth driving the population underground. 
Hardoon, a billionaire with plans to take over everything has the foresight to build a concrete pyramid to protect himself from the apocalyptic winds. Underneath is a system of bunkers housing his own private army.
This is the first floor of his apartment within the pyramid. 
I decided to design it in a retro brutalist architecture style. I was aiming for a James Bond style villain’s lair.
J. G. Ballard’s style is well matched with lots of concrete and since the novel came out in the early 60’s I didn’t want it to look too contemporary.
