When Mexico City-based real estate developer Inmobiliaria Brom set out to build its first U.S. project, it looked for a central location with available land and little office space.

It settled on Aventura, and it's not the only one. There is 436,514 square feet under construction in the city with internationally known Aventura Mall and high-end condominium towers. All will be Class A offices in a city where most of the existing inventory, nearly 799,000 square feet of a total of 1.13 million square feet, already is Class A, according to JLL data.

"Everything attracts me about the city," said Inmobiliaria Brom partner Ariel Bromberg. "We are at the border of two counties. We are close to Fort Lauderdale airport. The city is really booming. It's very international. I don't see anything that is not attracting us."
