Planter in middle with seating around
Love these rectangular concrete slabs
again with the rectangular slabs. Rocks would be easier to maintain, but will require regular sweeping/tidying.
you could do real wood fireplaces if they were in the wall like this. harder for drunks to fall into as well...
pavers with grass
love this wall, love the pavers. A built in water feature, the lights, it's all good.
simpel wooden benches like this would be great for brewery vibe. also cheap and easy.
a cool little entry thing like this would be neat.
that liitle fence is cool
you could have some area with pavers/grass, then an elevated sectio with decking... making different little areas/niches would be cool
shade covers for patio. retractable would be great so you could pull them back at night.
bamboo plants look good and easy
good shades and lighting
