I utilized a stone henge and built my base on top of it eventually extending downwards to the ground with walls / doors resulting in a fairly large hall. Planted a pine just outside which I used to make a large look out tower with a maypole and a nice bench at the top with some queens jam residing on top of a nearby stool. Fantastic view.
