The cost of an advanced home remodel varies according to the project’s scope, existing conditions, design requirements, permitting needs, consultant involvement, construction decisions, and level of detailing. Ortiz Mexia Projects, Inc. does not publish standard pricing because each residence is different. A consultation can help clarify the project brief, priorities, anticipated phases, and factors that will influence the overall investment.
