Generate a highly detailed 2D front elevation of a minimalist building designed to resemble the profile of a Christmas tree. The structure should feature a clean, symmetrical triangular shape, capturing the iconic form of a Christmas tree through simple, conceptual, and well-defined architectural elements. Design the 'branches' as horizontal slabs or platforms that decrease in width as they ascend, creating a stepped silhouette. The top of the building should include a sleek, geometric representation of a star. The façade should remain minimal, with subtle lines and textures that emphasize simplicity and modernity. Incorporate key conceptual details: Use continuous lines or modular elements to represent the layers of the tree without excessive ornamentation. Add vertical and horizontal divisions that suggest functional spaces, while maintaining a cohesive and elegant aesthetic. Include subtle accents like perforations or grooves to evoke a sense of depth and refinement. Focus on clean geometry, proportion, and balance. Avoid intricate decorations, prioritizing clarity and abstraction in the design. Ensure the drawing highlights the essence of the Christmas tree while maintaining a professional and minimalist architectural expression.
