Looking for ideas on Pergola DIY!

[Vu V.]

Hi there!

I'm looking to do something with the space but have been quite indecisive, hence I'd like to ask our community :)

The space is around 24' x 14'. The bars are around 8' in height measuring from the ground to the lower edge of the wood beams

I'm thinking about building a pergola for cheap (<$1k if possible) like below but would like some opinions on what to do with the concrete ground? Should I demo it and put dirt? What considerations should I take? 

I could also build a wooden deck but that would just cover up the messy ground. However, it would need to be anchored. 

Hopefully, I can get some input from you! If you've done this before, please let me know what it was that you ended up doing.

The location of this section is about 15ft away from the main house.
