Just enough elbow room so that the kids truly have their own space to spread out and study. We didn't have an inkling about Covid-19 when we were planning this space, but WOW...what a life-saver it has been in times of quarantine, distance learning, and beyond! Mixing budget items (i.e.Ikea) with custom details can often be a great use of resources when configuring a space - not everything has to be "designer label" to look good and function well.
