And what? The plans existed which the shelters were pretty much built to. End.

"Pretty much built to" ?

From your very own link, which you so thoughtfully provided.

" Above ground, each shelter's shafts were protected by specially constructed
'pill box' buildings to prevent any bombs that directly hit the location from
going underground. Each pill box housed lift machinery and provided the cover
for spiral staircases down to the shelter's tunnels."

"Two pairs of shafts were sunk for each shelter, with the pairs being sited
a distance from each other in case a bomb struck, blocking a shaft."

"Toilet facilities were constructed near the lift shafts, with the sewage being
periodically hydraulically pumped up a rising main to a sewer close to surface
level. There was storage capacity of 5 days for sewage should the hydraulic
mechanism fail for some reason."

"The air was filtered in case of gas attack. All doors were gas seals when closed,
and should there be an attack, the entrance doorways would be shut, with the
air passing through grilles in the roof of the pill box (clearly visible on
the Goodge Street picture below) and through gas filtration equipment."
