Faraday Zones are a neat idea! I've already got one by accident (sort of) in my home office, we extended the house and have our huge steel balcony inside our house[0] now, and it (along with huge steel struts through the house) means that wifi refuses to make it to the office.

Wonder how you'd be able to create a space like that on purpose?
