Act as a professional logo designer with 10+ years of experience in sustainable branding. Create a minimalist yet impactful logo for a green architecture firm specializing in eco-friendly designs. The logo should incorporate [LEAF SYMBOLISM], [MODERN GEOMETRIC SHAPES], and a [NEUTRAL EARTH-TONE PALETTE]. Emphasize clean lines, scalability, and versatility for use on business cards, websites, and building signage. Avoid clichés like overused tree icons—instead, focus on abstract representations of sustainability, such as interconnected lines symbolizing energy efficiency or a subtle building silhouette fused with natural elements. Ensure the design aligns with high-end architectural aesthetics while conveying environmental responsibility. The final deliverable should be a vector-based, high-resolution file suitable for professional branding.
