Basement Structure

Posted by Helmut Forren on Nov 29 in Foundation | 0 comments

A major part of what holds the roof up are four 20′ tall, steel columns made from 6″ x 12″ tube.  They are embedded 11′ into the basement concrete, and stick up 9′ in a vertical cantilever to hold the roof both up and firm.  The two that frame the front door can be seen below, with the street (cul-de-sac) in the background.
