"Create a multi-level interior design concept focusing on residential living. The design should feature various levels with both private and public spaces. The ground floor should include a spacious entrance area, a communal room for gatherings, an open kitchen with a dining area, and access to a community garden. The mezzanine level should house a quiet library or reading room and a fitness/wellness area. The upper levels should contain private bedrooms with en-suite bathrooms and private balconies or terraces. The rooftop should be a community garden with individual plots for gardening. Include natural light, green walls, and indoor plants to promote health and wellness. The circulation areas like staircases and ramps should be organically designed with seating areas and visual connections between levels. Incorporate modern, sustainable materials and biophilic design elements. The overall aesthetic should be modern, clean, and inviting, with an emphasis on community and well-being." --s 50
