GK Engineers is the MEP engineer for the conversion of eight ninth-floor suites, including the Presidential Suite, into sixteen guest rooms at the Hilton Houston Plaza Medical Center. The work adds keys to an operating hotel without changing its footprint.

No as-built drawings existed, so GK field surveyed the floor, traced the existing risers and branch piping, and designed each new room with its own HVAC unit matching the hotel’s existing system. Sub-panels, plumbing and bath exhaust were added for every new key.

This is GK’s third assignment at the property since 2020. The permit set cleared City of Houston review in early 2026, and GK is supporting construction.
