End of week eight

 

This week you can clearly see the walls on the first floor and in the picture below there's a good view through the main rooms at this level.

After another week of excavations, the underground matrix of pipes seems to have reached the end now and the vertical pipe marks the point of the air inlet. I'm hoping this is not what it will look like by the end of the installation but it's going to add something of a space-age touch to the wildlife area. I don't suppose I can plant anything too close to it to obscure it.
