A Strategic Head Start — Time Is the Ultimate Luxury

The lot comes with a finished 8000 sq ft footprint/ foundation, with a grid of 69 auger cast pilings. Each piling is two and a half feet in diameter that goes down nearly 70 feet below the base. What this means is that every square inch of the existing foundation is load bearing ie, In other words, there is flexibility and freedom to build almost any home or type of structure you could dream of.
Maximum Design Flexibility
Flexibility is the name of the game. Because the foundation is so over-engineered, every square inch of it is load-bearing.
Structural Confidence & Build Optionality: Engineered foundation provides exceptional structural flexibility, reducing build uncertainty and accelerating construction readiness.
