Small Apartment Interior Layout and Moodboard

Create a simple interior concept for a small apartment (about 45-55 m2). I need a clear plan for furniture placement and a calm modern look that is easy to buy and repeat. What I will provide: room measurements, photos/video, and a short list of things I must keep. What I need from you: a basic layout plan with dimensions, a moodboard with colors and materials, suggested furniture pieces (not exact brands, just type and approximate size), simple lighting suggestions, and 2-3 basic 3D views or realistic renders to understand the space. Style: modern, warm, light colors, practical storage. Important: keep it realistic for a normal budget, avoid custom expensive items, and make sure walkways feel comfortable. Deliverables in PDF + source files if you use SketchUp or similar.
