Transform this empty construction room into a premium

Transform this empty construction room into a premium modern home office while keeping the exact same room dimensions, camera angle, perspective, window position, ceiling height, and architectural structure unchanged. Design a luxurious workspace with warm walnut wood paneling, a large floating executive desk, an ergonomic designer chair, built-in shelving, concealed LED lighting, textured microcement walls, black metal accents, natural stone details, minimalist decor, indoor plants, and floor-to-ceiling curtains. Maximize natural daylight from the window, use soft warm ambient lighting, create a clean high-end architectural aesthetic, ultra-realistic materials, photorealistic 8K interior render, magazine-quality visualization. Do not alter the room layout or expand the space.
