I think I just heard several MPs having an evilgasm.
Looking through walls, now easier than ever
Seeing through walls, a capability available to law enforcement and military authorities for several years, could become a bit more predictable in the future thanks to a technique developed by researchers at Duke University. In a paper published on Thursday in the journal Optica, Duke professors Daniel Marks and David R. Smith …

At these frequencies a traditional faraday cage made of mesh will probably not be effective unless the mesh is very fine (under 0.5cm wire spacing). A cage made of sheet metal (eg aluminium foil) would be a better bet. Include some moving corner cube reflectors in the room to swamp the desired target (human) reflections with spurious reflections.
Of course if you want to keep something secret you need your own underground bunker - ten feet of damp earth will completely defeat this technique.

Mark 85 needs to investigate electrically conductive paint. At £165 a litre, doing the outside of the house might prove expensive, mind you. If he orders now he'll have it in time for Crimble, although I can't see a gift wrap option on Amazon for this.

We're getting ready to build a new house (owner builder), and I'm really considering wrapping the whole thing in foil that's properly grounded.
It would kill cell phone usage. However, maybe our guests would actually want to talk instead of just sitting with their face stuck to their goddam phones. My long time best friend from out of state visited with his wife a while back, and I don't think he had his iCrap out of his hand for more than 10 minutes the whole weekend!

Handheld units $6000 in low volume
If there was a market for this technology (presumably for a purpose other than spying on your neighbors) and Apple or Samsung decided they wanted to build into their phones, the tech could be mass produced for a fraction of that price. Handheld GPS units used to cost $6000 once upon a time...
Imagine a world where your annoying neighbor would knock on the door and you can't pretend you aren't home because they can see you through your walls!

Faraday+?
So far; static picture from the walls and wavelengths short enough to penetrate a Faraday cage.
Is one counter measure to feed random radio noise into (or just outside) your Faraday cage walls? Possibly around the frequencies the scanner uses?
Random search engine fettling suggests a cage (mesh) is less effective than a shield (kitchen foil). Also, windows. Metal blinds? I think the market is for detectors which alarm if you are being scanned, plus possibly scramblers which kick in if the alarm goes.
Also, tin foil underwear to match the hat. Faraday Bloomers. Kickstarter ahoy! :-)

Re: tin foil underwear
Tin foil underwear - these guys have it. And an EMP blaster to short out unwanted electronics.

That's an active jammer and illegal under US federal law. This is true of the LEOs, too, though. AFAIK, only the military can use jammers and only while in active operations.

Ironically, there's a real life equivalent:
