A4

🏭 2. Filming Hangar A4 (Territory of Crazy Challenges)

The hangar is a colossal, enclosed filming studio, several hundred square meters in area, with high ceilings (approximately 7-8 meters). Its interior is completely free of street light, allowing for professional studio lighting to be set up for filming at any time of day.
• Large-scale structures: This is an empty, technologically advanced space, inside which builders and prop makers can erect absolutely anything in a couple of days: a giant cardboard maze, a full-fledged prison, an abandoned school, or a multi-layered obstacle course for the show “The Floor is Lava.”
• Professional lighting and trusses: Massive metal trusses are stretched across the hangar ceiling, holding dozens of softboxes, spotlights, and adjustable RGB lighting that changes the color of the pavilion depending on the atmosphere of the video (for example, an ominous red when the Clown appears).
• Car Entry: One of the hangar's signature features is its enormous entry gate. Thanks to it, the team's famous supercars—an orange Lamborghini, a Mercedes-Benz G-Class, and other cars—are driven right into the pavilion for challenges like "Who can be the last to remove their hand from the car?"
• Prop Storage Areas: Adjacent to the hangar are massive storage areas that house tons of tape, thousands of yards of film, foam cubes, ball pits, inflatable boats, and hundreds of Nerf toy blasters, all ready for the next shoot.

The A4 Production office and filming hangar are more than just workspaces; they're a fully-fledged interactive world, designed for filming large-scale shows. Over the course of the channel's history, the team has moved to several locations in Minsk before settling in Moscow.
The production space is divided into two key zones: a stylish creative office and a giant filming hangar (pavilion).

🏢 1. A4 Production Office (Brain and Headquarters)

The company's office looks like a modern IT space in a loft style, mixed with bright gaming elements.
• Design and Colors: The interior is stylish, yet vibrant. The signature orange, neon green, and blue colors associated with the Lava Lava brand and products are found throughout. Huge neon "A4" signs, graffiti, and company logos adorn the walls.
• Relaxation and Gaming Area: A spacious lounge area with plush sofas (often yellow or orange) where the team gathers for brainstorming sessions. It features game consoles, arcade machines, foosball tables, and large TVs.
• Kitchen-cafeteria: A special area filled to the brim with branded stands selling chips, crackers, and Lava Lava lemonade. Bloggers often test new flavors right here.
• Vlad Paper's Office: Vlad's workspace is a stylish, minimalist space with panoramic windows, a large director's desk, a powerful PC, and shelves that house YouTube's top awards—Silver, Gold, and the legendary Diamond Play Button.
• Dressing and Costume Room: A separate room with mirrors where actors transform into their characters. The famous shiny jackets of the A4 Clown, the Evil Scientist costumes, the monster costumes, and racks of masks hang there.

The YouTube channel "A4" is one of the largest, most successful, and most popular entertainment channels for children and teens worldwide. Its creator and main personality is Belarusian video blogger Vlad Bumaga (Vlad A4).
