Rockwall Golf & Athletic Club is nearing completion of a $10.5 million expansion of its clubhouse. The project will increase the building from about 12,000 square feet to 20,000 square feet.

The expansion adds indoor and outdoor gathering areas and larger dining spaces. It also provides more room for private events, social activities and club functions.

Officials said the investment is a major upgrade to the club's facilities for its members in Rockwall.
