You can't do this with networkd alone, as it cannot yet distinguish between
different Wi-Fi SSIDs. (Open a feature request on Github.) NetworkManager,
connman, or perhaps a recent dhcpcd (which AFAIK introduced wpa_supplicant
support recently) would work better in this case.

Unfortunately, wired LANs don't even *have* anything like a SSID, so tools
can't distinguish between them at all. Really, just use DHCP at home...
But some of them (e.g. NetworkManager) allow manually switching between
connection profiles, e.g. you can have a "DHCP" profile and a "Work -
