display table for Houseworks Street of Shops

I ordered a sofa table from Overstock. com planning to use it to display my Street of Shops.  It arrived really fast, was easy to assemble and it's BIG enough.  So there's plenty of room for the
shops and even enough space to add a Tea Garden between the Tea Room and the Corner Bakery. 
That is, IF I can ever figure out how to create one that doesn't look amateurish next to the shops.

I tried bashing a pergola kit to fit the space available but I'm not real happy with the way it looks.   
And I'm finding that elements I thought would work just fine - don't.  So I'm now re-thinking everything.

Here are the shops on their new display table:
