Investing through a company named California Forever, which saw the launch of its official website on Thursday, tech billionaires are laying out the blueprint for a dream city in Northern California.

On its website, California Forever said it has acquired over 50,000 acres (or 202 square kilometres) of land through its subsidiary – Flannery Associates – in eastern Solano County, which is nestled between Sacramento, the Sacramento-San Joaquin River Delta, San Francisco and Napa Valley in Northern California.

Located at the crossroads of major Northern California cities, Solano County is touted by the company as the perfect place to build the dream city from scratch.
