Since opening in 1985, this 50-story tower has become an iconic part of the Dallas skyline. Original construction was of the highest quality, but admittedly representative of its era. Thus, ownership was motivated to pursue a modernizing renovation. It was decided that the entrances and lobbies would be the focus of the interior updates.
The ground and second floor are the heart of the building’s interior. So, the new design needed to make a lasting visual impression. Additionally, with roughly 1.2 million square-feet of office space the buildings core had a large population to logistically accommodate. To accomplish this, the existing lobby areas were largely demolished, with a new design based around a first-to-second-floor open-air connection of lobby spaces.
Noir St. Laurent marble was chosen as the interior flooring material to tie lobby areas together. It was installed in a size format of 2’-6” x 5’. To contrast the darker flooring selection, white and gray marbles were utilized at walls. Bianco Dolomiti Turkish marble was used as the typical large-format lobby wall veneer panels. At the Monumental Stair and entrance portals, Greek Stellar White marble was the cladding material of choice. Finally, Corticcia marble was selected at the Featurewall. The Featurewall proved to be a very challenging element as it utilized several finishes, had a series of decorative recessed vertical joints, was available in limited quarry block sizes, and was book-matched.
A survey of materials tallied a total of 35,000 square-feet of interior stone finishes. Due to a carefully detailed & phased schedule, the building was able to remain in operation during renovation. This stonework was accomplished over a period of roughly 10 months, by the same stone subcontracting company that had erected the building’s original stonework in the mid 1980’s.
