In 2008 Marek Dallas took on the prestigious job to build the tallest building in Oklahoma City. Marek helped complete the drywall and acoustical ceilings in the 52 story building. The 844 foot structure dwarfs the rest of the downtown buildings from some angles. The 3-sided glass tower features diamond-shaped faces at the top, a 100' by 100' glass rotunda just beside it and a six-story "podium" stretching to west to Hudson. The "podium" has auditoriums, classrooms and offices. Reflecting pools sit at the base of the tower, and a transparent wall allows those passing by to see into the tower lobby.
Each floor has 25,000 to 28,000 square feet, collectively housing up to 3,000 Devon Energy Corp. employees, consultants and contractors. Designers emphasized, however, that they want the ground level of the structure to be the "heart of downtown," a place for the public to gather at restaurants and shops. For example, Nebu is the casual food court and dining area in the garden wing. It includes a wide array of options such as sandwiches, pizza, sushi, salad and gourmet Italian coffees.
