Yes, there have been instances where a home remodel is so extensive that it essentially becomes a brand new construction. This type of renovation is often referred to as a "gut renovation" or "whole-house remodel."
During a complete remodel, almost everything in the house is torn down to the studs or even further, including walls, floors, ceilings, plumbing, electrical wiring, and sometimes the foundation. The goal is to create a completely updated and modern space with new layouts, fixtures, and finishes.
In some cases, only the home's original framework or shell remains intact, while everything else is rebuilt from scratch. This can involve adding new rooms, expanding the property, or completely reconfiguring the floor plan to better suit the homeowner's needs and preferences.
Gut renovations are common when the existing structure is outdated, severely damaged, or does not meet modern building codes and standards. Homeowners may choose to go this route to create their dream home without the limitations of the original structure.
Keep in mind that such extensive remodels can be costly and time-consuming, often requiring significant planning, design work, and professional expertise from architects, contractors, and other specialists.
