Re: Walls Are Moving
Unfortunately no one can really offer specific recommendations over the internet --- sight unseen -- cables or rods with turnbuckles -- perhaps.

There may also be foundation issues causing the walls to bow out.
A structural engineer would be a good choice to evaluate the structure and make appropriate recommendations.
