Open plan kitchen/diner….Do you think 225cm width space is sufficient for a usable dining table and chairs? The gap is between island and top of three steps down into garden room. Everything I read tells me you need a meter clear on both sides of dining table (let’s assume table width is 90cm)…so that would make a space of 290cm required but having measured it out that seems insanely generous…I think 65cms each side looks doable but tight. Clearly I don’t want people tumbling down the stairs! Is this craziness?
