I’d sketch a simple, symmetrical floor plan. Start with a large, centered arena – a perfect square gives that balanced feel. Put a focal point in the middle, like a raised pedestal or a low wall, that draws the eye and gives you a clear line of sight. Around the edges, arrange identical obstacles – maybe low walls or panels – so you see the same layout from any angle. Keep the lighting from one side to create dramatic shadows but keep the overall shape uncluttered. This way you have a slightly larger open space for movement, but the negative space and symmetry keep the arena looking like a work of art while still letting you dominate.
