Working remotely requires some investments: dedicated room for office, good chair, conference set. Most people just try to code on sofa at living room, and fail.
You definitely need a dedicated office space. Especially when you got kids in the house! When we were looking for a house, having a sweet office space was one of the major factors. My office is away from the family common areas, on a different floor, and the noise I hear is minimal if any.
This issue is one big reason why my attempt at remote working failed. If I had had a basement office, away from the rest of my family, it very well could have worked. But I couldn't get physically enough out of sight to be also mentally out of sight.
