Sure, think of the building as a blank canvas that can change colors. Keep the core geometry simple – a strong, flexible grid that stays the same no matter what sits inside it. Use movable walls and modular partitions so you can carve out spaces without re‑engineering the whole frame. Let the negative space be the building’s breathing room; keep corridors wide, let light flood through skylights or large openings that remain useful whether it’s a gallery or a loft. The trick is to design the circulation and structural skeleton first, then layer the function on top – that way the empty zones stay meaningful even when the purpose flips.

You’re right, the walls need to look like they’ve always been there, not a temporary patch, so a concealed sliding mechanism that follows the same material palette will do the trick. And those skylights? They have to line up with the grid like a well‑tuned metronome, otherwise the light will feel like it’s doing its own dance. Keep the skeleton solid and let the layers play around it – that’s the only way the negative space will keep its rhythm.
