Re: Building an Interior Wall
Cut out the dropped ceiling(gawd, please no!)and bring the framing up to the old ceiling?
That would be the strongest method .... however .... if you are fastening the bottom plates securely to the floor and the 2 side walls to a existing rigid backwall then using some construction adhesive and drywall anchors for the top plate will work.
This will depend on what you will be using for a covering over the studs ... example ... drywall and stone or brick .... then hang a 50 inch plasma .... the top might be a little shakey and you may end up with some cracking at the joint near the ceiling.
