This used to be a water runoff area. There was a bridge across it that was basically rotting and falling apart.
We turned it into an outdoor event space. Fire pit, lights at night, elevated about two feet so you'd never know all that water runoff is still underneath. Tenants use it free for client appreciation events, happy hours, networking, whatever they want.
Nobody looks at a drainage ditch and sees an asset. That's exactly why it was one.
What's the ugliest part of your property you haven't figured out how to use yet?
