HOUSTON (CultureMap Houston) – Between Chevron’s recently announced building at 1600 Louisiana and Skanska’s plans for 811 Rusk, there’s no shortage of activity in the city’s downtown area.

And now Hines is lining up a project there as well.

The development company told CultureMap earlier this year that it would build a 41-story office building at 609 Main St. Those plans are still a go, but the size has changed.

“Because of demand, the building’s size is expected to grow from the initial 815,000-sf concept,” said John Mooz, senior managing director in Hines’ southwest regional office.

Connecticut-based Pickard Chilton will finish designing the skyscraper later this year. Until then, the building’s exact height and size are unknown.

Mooz said they haven’t signed a tenant yet, but they expect to break ground in first quarter 2014.

The building will be at the corner of Main and Texas Ave., one block from the tallest building in Texas — the 75-story JP Morgan Chase Tower, also developed by Hines.
