Sliding security door

We wanting to install sliding door in short hallway to block off room to create an room we can rent out. Prefer door to slide into bedroom wall when not in use. Approx dimensions are 780x2405mm (wxh). Picture shows 2 doors on left. Sliding to go across hallway in between rooms and hopefully slide into wall there. It does miss fuse box in upper right of opposing wall. If sliding wall not possible then possibly a wall to just secure in place when required?
