An elegant and modern logo for 'WhiteLeaf Building Group.' The logo should feature a clean, minimalist design with a white leaf as the central element. The leaf should be stylized, perhaps with gentle curves or geometric lines, to evoke a sense of both nature and modernity. The company name 'WhiteLeaf Building Group' should be included in a sleek, sophisticated font, possibly in a muted green or gray color to complement the white leaf. The overall design should convey professionalism, quality, and a connection to nature, suitable for a high-end residential construction company in Victoria, Australia.
