Use the uploaded architectural perspective sketch as the sole geometric authority. Preserve the exact camera, vanishing points, building silhouette, floor levels, wall positions, roof lines, window openings and courtyard proportions. Convert it into a premium photorealistic tropical architecture visualization. Apply warm teak to the existing screens, honed warm-grey stone to existing masonry and subtle cream mineral plaster to solid walls. If a material board is supplied, it overrides these example finishes. Retain all original trees and planting positions; use believable Malaysian/Singaporean tropical species. Use soft late-afternoon tropical daylight, controlled highlights, physically plausible glass and timber grain, natural contact shadows and restrained color grading. Preserve the full original framing. Do not add floors, openings, furniture, landscaping or structural elements absent from the sketch. Remove sketch linework in the finished output. Output one image without labels, logos or watermarks. This is a concept visualization; verify all dimensions and constructability independently.
