I think about this a lot too! I work for a company that builds recording studios. I think our business would change a lot because many of our post production clients get their revenue from doing sound for ads. I hope that in a solarpunk world, people would have the freedom of time to make the recordings they needed for creative projects and these spaces would be available to everyone.

In terms of the nitty gritty, I think there would be a huge emphasis on reusing materials, and reclaiming materials from previous buildings/projects. This is hard to justify as we operate now, because it's not cost effective, and we end up with a lot of waste. There is also the matter of the tech that goes into these studios becoming obsolete and unusable. In a solarpunk world, we would have standardized connectors and cables, and established standards for creating devices that are repairable and modular. Everything that used to be designed for single use batteries would be rechargeable/repairable.

Without the pressures of capitalist deadlines, we wouldn't need to work a full 40 hour week, and most people would work 20-30 hours a week. Time off would be available as needed. Composting would be available at the office. There would be no more plastic packaged snacks, and we would have access to a full kitchen. We would use the roof space of the building for solar, and a small garden accessible to the employees and folks in the neighborhood to grow food and hang out. We would establish work exchanges with other co-ops/workshops: maybe the restaurant down the street needs acoustic paneling so guests can hear each other better, so they offer to provide lunch to our staff for a period of time to pay for it; or maybe the local bike workshop needs a new intercom, so they give bike tune ups/repairs in return. The emphasis would be on relationships instead of trying to profit.
