Removal of Interior Wall

[SeanDelere2]

Happy New Year to Everyone.

We are partitioning off part of an upstairs bedroom to make a small room for a toilet. I have started to remove a small none structural wall (there is nothing above it in the ceiling and it is built on top of the floorboards)

I intend to build a wooden frame to support the existing door frame into the bedroom and the new toilet.

My question is whether I need to 'tie in' the wall next to the stairs to the remaining walls for the other bedrooms. Please see my drawing and photos.

Any advice will be most welcome.

Not entirely sure what you mean but any walls of this nature are not meant to be 'free ended'.

It looks as though you have standard 3" partition block walling upstairs, usually built off a sole plate and often trapped in by the plasterboard ceilings, at the top. These walls do not have much in the way of linear strength so any changes in wall direction helps and any timber framing elements need to be securely fixed.

My feelings are that the wall should be reinforced with a 6" wide plank fixed across its end so it stops the wall flexing. this gives the opportunity to fix the plank with long fixings into the end of thee wall.
This brings me to a second point, trying to fix the door frame directly on to the end of the wall would mean that the frame fixings would be about 2" in from the cut end of the wall. I think this would be too fragile.
It sounds expensive, but if the door frame was made between two pieces of 3" X 3" (floor to ceiling) and both bits of wood then fixed into the ends of the wall this would result in a better job. It would be a shame if the bits of wood warped!

Thanks for the replies.

I have now removed the remaining parts of the wall and have tidied things up. I think my plan will be to fit two 4 x 3 above the door frame to secure the existing door frame to the 'stairs' wall. I will also attach the two walls above the ceiling to provide further strength.

Thanks once again.
