Fixed-Price Mini Task: 2D Renovation Feasibility Concept for Older Three-Level Apartment

Important: This is a small fixed-price pre-purchase feasibility task, not a full architectural design project. My budget is $40–$50 total. I am not looking for a full design package, detailed architectural drawings, 3D renders, permit work, or execution-level planning at this stage...
