This Brooklyn garden is a great big city oasis, refreshing and inviting. There’s a deck and staircase made of steel with decking and stair treads. The landing and bottom steps are stacked limestone, with one ipe tread overlapping the stone; the wooden planks is elongated to stretch along the length of the garden like an elevated path—at the right height to double as bench seating. Visible on the left, along the cedar fence line, is a magnolia tree that belongs to neighbors and hangs over the garden. The patio and pathway pavers are limestone, as well, edged by crushed limestone dust mixed with gravel.
