Landscape Architect advice, mix of hardscape and structure

Hi all,

As much as we love the overgrown weeds in our tiny patch of jungle, it's time to redo our backyard. It's small, maybe 15 x 40, and doubles as a parking lot on occasion. Taller neighbors also loom over us, so we might some type of trellis/arbor for privacy. We imagine a mix of hardscape and plants around the edges. Do you have recommendations?

Thanks
