Network Architecture: ZIP-First, City-Second

Each Domaine node is anchored by 1-3 verified affluent ZIP codes or postal districts. The ZIP proves the luxury floor; the city becomes the Domaine page.

US Domestic (12): Enclave-to-enclave pages. Beverly Hills 90210 to River Oaks 77019.

International (7): City-level pages with postal-district anchors. London W1K/SW1X to Houston.

Texas (6): Intra-state luxury corridors always kept -- relocation is core brand.

25 NODES: 12 US + 7 International + 6 Texas. Each backed by world-class affluent ZIP/postal codes with verified Houston wealth-flow relevance.

Methodology: ZIP-First Architecture

Step 1: Identify Most Affluent ZIP Codes / Postal Districts

  • US: PropertyShark Top 100 Most Expensive ZIP Codes (2024/2025), Census ACS median household income by ZIP
  • International: Knight Frank prime residential indices, Henley HNWI migration data, local market reports
  • Threshold: $800K+ median sale price (US) or equivalent luxury floor (international)

Step 2: Map ZIP to City (Domaine Node)

  • ZIP 90210 (Beverly Hills) maps to Node: Los Angeles
  • ZIP W1K (Mayfair) maps to Node: London
  • Multiple ZIPs can anchor one city (NYC has Tribeca + Hamptons as separate due to distinct buyer profiles)

Step 3: Validate Houston Corridor Relevance

  • Verified wealth flow between ZIP's metro and Houston (Census ACS, Redfin, HireAHelper)
  • HNWI from this area buying $800K+ properties in Houston (NAR, TPJG CRM, HAR)
  • Corporate/industry transfer corridor exists (energy, finance, tech)
  • Nodes without verified Houston relevance excluded (e.g., Aspen 81611 = extreme wealth but minimal Houston corridor)

Step 4: Texas Always Kept (Joseph Directive)

  • Intra-state luxury relocation is core to The Domaine brand
  • DFW-Houston is highest-volume luxury corridor in Texas
  • Austin-Houston growing with tech wealth; San Antonio at threshold
