Reihenhäuser für Vögel

That translates as "Terraced Housing for Birds" or something very close to it.

A rainy day here.  Very rainy. 

So we stayed in and had a look at how else we could arrange the lounge/sitting room/the-place-where-we-watch-telly.  Thrilling.

If you're interested, the middle house and the one in the right are occupied.
