Extend the loft hatch opening

carpentryframingloft

I am hoping to extend the opening for my loft hatch using the following method.

I want to move the cross piece from position Q to position P. I intend to screw a temporary support across the top of the joists at position P. Then remove the cross piece at position Q, cut joist B where it intersects with line P and reattached the removed cross piece by screwing it to joist A and C. I will then remove the temporary support.

I have two questions:

  1. Does this method sound sensible?
  2. The cross piece is currently nailed between joists A and C. How can I go about removing it? The nails are driven in below the surface so I can't see how to get any tool on to them. Is there some other method? Ideally I would like to reuse the cross piece, but I can replace it if necessary.

Your plan sounds fine.

If it were me, I would likely do the temporary support from beneath (a temporary stud extending from the floor below, intersecting the ceiling at the intersection of B and P). Either way, I think you will be fine.

A reciprocating saw is the right tool for this job. It will allow you to cut the nails holding the existing cross member in place.

I'm not sure of your particular situation, but since you are already reframing the opening, you should consider adding a drop-down ladder. As long as you have the space, this will make the attic much more usable in general.
