My observatory next to the house + dog in foreground (krypto);
It's a standard garden shed but with a modified roof, consisting of 8 leaves that open out, I like to think, as a lotus, but this may require some enhanced imagination.
The rain does not get in inspite of the short overhang. This lack of overhang is due to the hinge construction needed to make the separate leaves of the roof openable.
Later I decided that some camoflage would be a good thing
As you can see I've added some camouflage to the outside.... I think it looks cool anyway.
