Most of the core departments of the company like the human resources, finance, and marketing are located in the building.

The network's post-production unit, engineering department, program management, and talent development (Sparkle GMA Artist Center) are also located in the building.

The GMA Network complex has a total area of 17,184 square meters (184,970 sq ft)[3] (including the 4,053 sqm Studio Annex) located in EDSA corner Timog Avenue, Barangay South Triangle, Diliman, Quezon City.

The network has held office in the complex beginning in 1957 with its television broadcasts started in 1961, having moved from the Calvo Building along Escolta in Binondo, Manila.

At that building, the network, then known as Loreto F. de Hemedes, Inc., later renamed Republic Broadcasting System, had its first studios and corporate offices since its inception in 1950.

On the Network Center's front, a sculpture called "Beyond Broadcasting" was built and designed by the artist, Eduardo Castrillo.

The building houses two state-of-the art HD studios, as well as offices for GMA Network's subsidiaries and departments.

The Studio Annex was unveiled on October 17, 2008, with a red carpet event attended by the network's personalities, executives and government officials including the country's then-president Gloria Macapagal-Arroyo and then-vice president Noli de Castro.

The building is located next to the GMA–Kamuning MRT station and EDSA, so loud noise from these is a major problem for the studios.
