"I've talked to someone who lives in a roundhouse (Fuller dome) and the curved furniture does make it not worth doing. They have built-in countertops (out from the center) but sticking furniture up against the wall is a daily annoyance.My idea of how to get around this was simply to use a polygon instead of a circle. Studs are typically spaced 16" (.4 metre) apart, 24" (.6 metre) also happens.I wonder if you could get a significant part of the benefits of curvature (mainly = removing the extremely sharp 90-degree angle as it impacts vision and movement) making e.g. 10-degree bends every 3 metres (6 studs).If you want a nice long table up against the wall, it should be at least 2 metres, this is a full reach out with both hands.Bookshelves and storage cubes, similar. IKEA's largest KALLAX is 62" (1.6 metres).Moving around spaces that feel spacious, the 2-metre measurement seems like an important one to me. Can two people pass each other comfortably (without turning sideways)? That might necessitate two wingspans in a kitchen. Conversely, can the cook get from the counter to the island in one step? A step is about a metre (half a wingspan)."
