A pre-submittal cover sheet for Summit House, Lot E21, lists 15 firms. Hart Howerton is the design architect on that sheet, and SCB is the executive architect. [NVBEX](https://nevbex.com/2026/10/14/summit-house-summerlin-condo-development/) names those two and five more of the same firms in its October 14, 2026 report.
