Minimalist Architectural Blender Model (2 floors)

I have a set of architectural plans of a duplex apartment. I need that turned into a clean, well-organized Blender file. The focus is strictly on the basic structure and layout—no detailed furnishings, textures, or lighting at this stage. Everything should follow a minimalist aesthetic, so keep the geometry lean, name objects logically, and group elements in a way that makes future iterations effortless.

You’ll receive the PDF drawings as soon as we start; from there, I expect a single .blend file with accurate dimensions, separate collections for walls, floors, roof, and openings, and no extra modifiers left unapplied. If you model efficiently and keep the file tidy, we’ll have more phases to add detail later.

1) Please send me an example of something you already did.
2) Respect the plan spaces and proportions, no furniture, just walls
3) Let me know your budget and if 25EUR is OK for you. Sorry but I cannot accept anything higher than 25EUR
