The elevations show four wall perspectives (A-A, B-B, C-C, D-D) with detailed material specifications and fixture placements. Bathroom areas feature 400×400mm ceramic tiles in bright and dark color schemes with 20mm grout spacing. Gypsum board partitions separate functional zones, while the bathroom includes a vanity unit with dark emperador marble countertop. The drawing indicates MEP elements including FCU locations, AC supply/return grills, and sprinkler/smoke detector positions.

Interconnecting doors between king and twin rooms are specified with key plan reference points for contractor coordination.
