Kenwood: glasshouse & potting shed.

Partly due to lysergic-induced laissez faire, and partly because of the fact that there was no point fighting it, John began to occasionally leave the gates at Kenwood open, allowing fans to wander in at will. A few knocked on his door, but most skulked in the nether regions, leaving graffitied messages of devotion (to Paul) on his potting shed door, and smashing the windows of his greenhouse.
These two structures, tucked away at the bottom of the garden by the foot of the north perimeter steps, survived to the mid-90s, though the greenhouse (or glasshouse) was in a state of complete disrepair by that point. This section of the grounds was also allowed to go its own way during the 1980s, being left largely untended and inevitably becoming wild and overgrown in the process. The major 90s renovation saw the whole area cleared, and at that point the greenhouse also went the way of the weeds.
