Feedback Needed: AED 1.65B Luxury Waterfront Hospitality Concept for Palm Jebel Ali,

Hello BiggerPockets Community,As a Real Estate Master Planner, I have developed and finalized a comprehensive financial feasibility and capital structure for a premium hospitality development concept on Palm Jebel Ali, Dubai, named AQUA-VENICE.This is a pure "Concept & Financial Model" intended for a Joint Venture or outright Concept Sale, where the incoming developer/institutional fund will acquire the land and execute the construction.Here is the high-level financial framework we have optimized based on current Dubai luxury benchmarks:Initial CAPEX: AED 1,650,000,000 (Includes land acquisition, DLD fees, ultra-VIP villas, overwater cottages, and robotic parking structures).Projected Annual Gross Revenue: AED 280,080,000 (Assuming a stabilized occupancy structure).Annual OPEX: AED 44,400,000 (Human capital, DEWA, facility management).Projected Annual Net Profit: AED 235,680,000 (Pure retained earnings).Target Investment Payback Period: 7.0 Years (84 Months).Revenue Vectors:Ultra-VIP Enclave: 25 Waterfront Villas (AED 225k/day) & Bio-Filtered Marine Canal Experience (AED 150k/day).Premium Integrated Town: 50 Overwater Cottages (AED 175k/day), Luxury Fashion & Michelin Dining Promenade (AED 168k/day), and Automated Robotic Parking Hubs (AED 60k/day).I am seeking validation and experienced feedback from global institutional investors and developers on this platform:Does a 7-year capital recovery timeline for a mega-project of this scale align with your current international luxury benchmarks?Given the seasonal shifts in Dubai, what stress-testing factors or off-season occupancy rates would you recommend factoring into the OPEX/Revenue ratio?What is the best strategy to protect this intellectual property (IP) when pitching directly to major master developers like Nakheel or Emaar?Looking forward to your professional insights and technical feedback.Best Regards,Fazul RehmanGlobal Business Strategist & Real Estate Master Planner
