So you have everyone at home and don't know how you can do it for one more day! I feel 'ya. People are more familiar with their homes than ever before and trying to eek out a quiet space wherever they can find one...and where no one can find them.
But when you get down to it, the key ingredients are simple. All you need is a desk + a lamp + a great desk chair. The trickier part is figuring out where to put them.
How about behind a sofa? In almost any room there is usually space for a desk behind a sofa or sectional, as you would normally think to use a console table. During the day it might work as a quiet spot while kids are in school. And if you're anything like me, you continue to work when people return home, but you like to be part of what's going on. You can do this here.
