I also did a butcher block top. Cut it down and routed to perfectly flow around what passes for a "straight wall" in this house, spent entirely too long sanding and finishing.

Then put it on some IKEA drawer blocks, because I want drawers, but I'm not equipped to build those in any reasonable timeframe.

Cutting down a desk top is something you can do with sawhorses and some good weather. More intricate things need an actual workshop for good results.
