Located in Angra dos Reis, a vacation area between Rio and São Paulo, the island compound comprises 16 buildings with a combined 21,000 square feet of space. Although there’s a helipad, the mainland is only a 10-minute boat ride away. With its proximity to the coast, power is supplied by underwater electrical lines.

Price: $19.5 million
Size: 32 acres
Bedrooms: 8, plus staff quarters for 12

The main house has eight bedrooms, each of which has an en suite bathroom. There are also facilities where a staff of up to 12 can stay. The island, Bloch says, is designed to sustain a comparatively large group. Its solar panels “work about 85 percent of the time—it depends on how many people are on the island,” he says.
