Hello everyone,
I would like to undertake a DIY project to widen a door opening. A structural calculation is available (steel lintel HEB), and according to the planner, I should be able to handle it alone (leap of faith *grin*). In any case, I need to expand a wall opening from 1 meter to 2 meters (3.3 feet to 6.6 feet) in width because I want to install a double-leaf door. Fortunately, the room is still in the shell stage, and the clear height of the existing opening is about 2.75 meters (9 feet).
My question now is, how far above the new door opening (or above floor level) should I position the lintel? Regarding plastering and possibly screwing the door frame into the lintel, I could imagine this might be problematic. (For fire protection reasons, it does not have to be covered!)
