Prospect Street Capital has officially kicked off its latest health care venture, holding a ceremonial groundbreaking Tuesday for Queensridge Medical Plaza, a new medical-office campus planned on Alta Drive just east of Hualapai Way near Summerlin Hospital Medical Center. The project’s first phase calls for a pair of two-story buildings of roughly 45,000 square feet each on a site reported to cover about 12.2 acres. Developer Scott Goldstein said more than half the first-phase space is already presold, and that construction is expected to begin in July 2026, with the initial buildings wrapping up around spring 2027.
According to the Las Vegas Review‑Journal, Prospect Street Capital led the ceremony, and city records reviewed by the paper show plans for four buildings totaling about 178,400 square feet on the parcel. The Review‑Journal notes the site spans roughly 12.2 acres and that the developer is marketing the campus to physician-owners and outpatient practices.
What is planned
Marketing materials for the development list “Queensridge Office Condos,” framing the campus as a for-sale medical office opportunity rather than a traditional lease-only project. A LoopNet listing for 10000 Alta Drive shows a two-story, roughly 40,000-square-foot building with several condo units already under contract. The listing lays out unit sizes, sale status and a 2026 delivery year, reflecting the owner-user model Prospect Street is pitching to medical tenants. The master plan filed with the city would allow additional buildings on the parcel to be constructed in later phases.
Timeline and pre-sales
In an interview with the Las Vegas Review‑Journal, Scott Goldstein said he expects site work to start in July 2026 and for the two initial buildings to be finished by spring 2027. He told the paper that more than 50 percent of the phase-one space is already presold, characterizing the early commitments as a sign of strong demand from medical groups in the Summerlin submarket.
How it builds on an earlier Queensridge project
Prospect Street previously developed a three-story, 70,000-square-foot Queensridge Medical Office Building nearby. Trade coverage and the project's architect show that facility includes a surgery center, a cardiac cath lab and multiple specialty clinics. Coverage by Medical Construction & Design and the firm KGA Architecture list the earlier Queensridge work, underscoring Prospect Street’s continued focus on health-care real estate in the area. The new plaza appears intended to complement services at that building and at Summerlin Hospital by adding additional clinical and outpatient capacity.
What it means for Summerlin
If completed as planned, Queensridge Medical Plaza would add for-sale medical real estate that could lock in physician ownership and expand outpatient capacity on the valley’s west side. Industry coverage of the earlier Queensridge project has tracked growing outpatient construction in the region, a trend that developers say helps stabilize neighborhoods around major hospitals.
