Minimalist penthouse interior with red furniture overlooking architectural sketch cityscape

3D rendered architectural visualization depicting high-altitude living space with floor-to-ceiling glazing framing gridded urban skyline backdrop. Foreground dominates red quilted lounger with metal frame legs positioned on pale wood flooring. Minimal black wireframe table placed left. Interior walls rendered as transparent planes with crosshatching technique. Manhattan-style towers faintly sketched in background using architectural drawing methodology. Lighting combines natural daylight with subtle shadow mapping on furniture surfaces. Spatial depth constructed through receding lines and transparency overlays.
