There is no concern, nor can anyone viewing it full 500% zoom on a 24" monitor see one, to the right and left of door opening are single studs floor to ceiling that hold all load, to the right in corner is another full stud, above those is maybe a 4x6" beam under the joists that will stay supported. The corner is well built. To the left of the door are 2, 2x12 joists where stairs go up, supported by the full stud to the left of the door and another stud about only 12" further left. The 2 inner apx 7ft studs and one 12" center in the door middle do nothing for above support, they support the door itself, joists are still suported by the double 2x4 under joists. Remove those 3 and lath-plaster and nothing will happen. Its plain as day. Do you guys just guess, or actualy remove and design additions. This house was well built.
