Minimalist Guesthouse Floor Plans

I need a complete set of detailed floor plans for a two-bedroom minimalist guesthouse measuring between 700 – 900 sq ft. The core layout must integrate an open-concept living room, a efficient kitchen, one full bathroom, and a compact yet functional home office...
