Open Stairway

The owner of this home was finishing his own basement, but asked me to help him open up the stairway to the basement family room.

Here’s how it looked before:

The stairs ran parallel to the floor joists above, so removing the walls basically required adding support for the 3 short I-joists ending at the stairwell opening here:

We supported the end of these three floor joists with a double 2×10 built-up beam that transferred the weight to the joists on the sides of the stairwell.  These joists now taking the added load were strengthened by fastening an LVL beam along each.  Metal hangers were used at the connections.

So the load from the three joists was properly transferred to the sides of the stairwell, and then along those joists back to bearing points. We built a temporary support wall under the three joists while installing the new beams.  Then the temp. wall and stair walls were able to be safely removed.

Here’s what it looked like after:

It really opened things up!  We framed the sides of the stairs for future end caps and an open railing. The home owner said, “That went great and I’m very happy with the result.  Thanks a lot.  Great work!!!”

Consult with a structural engineer before making any structural changes to your home.
