This is a small garden project we did several years ago. The exterior fireplace is both a fireplace and an oyster pit.
You can build the fire in the fireplace and then rake the coals out into the oyster roasting area.
We designed the dining table and table for the grill. The dining table has a hole in the middle with a removable granite cover so the oyster shells can be discarded into a trash can below.
There is a "carpet" of bluestone set in the brick paving.
We also designed new gates.
