I am looking for optimal 2D furnishing layouts for a new kitchen and a combined, open-plan living and dining room. Based on the 2D floor plan I provide, please suggest the best furniture arrangement to maximize space and traffic flow. For the living/dining area, include a dining table, a spacious sitting area, and a TV. In the kitchen, the sink must be positioned directly under the window, and there must be a dedicated space for eating. Ensure the proposed layout strictly maintains the exact placement of all existing architectural features, particularly glass doors and windows.
