Trilogy at Summerlin and Siena are the two premium boutique gated options in the Las Vegas 55+ market — both under 2,500 homes, both in the Summerlin corridor, both commanding HOA premiums above the mass-market communities. They're fundamentally different experiences despite geographic proximity.

Trilogy is for buyers who want the absolute newest, highest-quality construction product in the market and are willing to pay the premium HOA and accept the social trade-off of a 354-home community. The Outlook Club's quality, the construction standards, and the culinary programming are genuinely the best in the Las Vegas 55+ market. The intimacy is either cherished or limiting depending on your social needs.
Siena is for buyers who want a specific combination that Trilogy doesn't offer: a guard gate that actually works (24/7 staffed), an on-site golf course, Lake Siena's waterfront setting, and a community large enough (2,000 homes) to support genuine club depth — all for $125/month less HOA than Trilogy. The construction is older but many homes have been renovated and the Tuscan aesthetic is distinctive.
You're paying $700K+ and want the newest build, best amenity quality, and culinary culture. You're socially self-sufficient with a partner and don't need 50+ clubs to be happy.
The guard gate matters. You play golf. The lake setting is part of the vision. You want more social variety than 354 homes can provide. You value the per-dollar comparison at $125/month less than Trilogy.
