Why Build a Backyard Office?
Prefab office pods cost $15,000–$50,000 delivered. Garage conversions average $15,000 and reduce resale value. Coworking spaces run $300–$500/month. The Ergosphere is a sound-isolated, climate-controlled workspace you build yourself for under $6,500 in materials — and take with you if you move.
