Avoid erasing character by stripping original features like curved walls and coved ceilings, which flatten the design and lose personality. Don’t overdo minimalism to the point where the space feels cold or barren. Also, avoid mixing too many flooring materials or clashing lighting temperatures that disrupt flow. Instead, preserve key architectural details, unify flooring, and layer lighting to maintain warmth. These choices ensure a modern remodel remains true to the home's unique 80s charm.
