Wi-Fi in a garden office

How do I get good Wi-Fi in a garden office or outbuilding?

The short answer

In a garden office or outbuilding the building is the limit, not the broadband. An outside wall, a garden, and another insulated wall to cross A buried or clipped outdoor network cable is the only reliable answer. We do not quote a single "walls cut the signal by X%" figure, because the loss depends entirely on what the wall is made of.
