Grounded - Richard Risner RLA, ASLA it's a custom edging made from corten steel. It's the same material I used for the fire element to the left and for the raised planter boxes in the far back of the photo.

VC Studio Inc. It's hard to tell from a distance shot, but with an edge that thick it's probably concrete.

Grounded - Richard Risner RLA, ASLA custom formed & poured concrete with a hard trowel finish.

Grounded - Richard Risner RLA, ASLA 5" wide. Its the smallest beach rock called "black button".

Grounded - Richard Risner RLA, ASLA If you use 2x4 (actual size is 1.5"x3.5") framing for each side and include the steel forming stakes (about .5" thick) to hold the 2x4 forms and some space (about 2") to nail (and remove) the stakes to the form boards that's how the paving gap gets to be that width. From trial and error, you can't use one form board to form both pavers simulataneously, it usually causes damage to one of the pavers when trying to remove the board. Yes it's expensive especially if you are considering the ashlar pattern.

elshootoe I figured my idea would expensive, and the payoff may not be worth the extra expense. Is there anyway to go thinner than the 2x4s? Would plywood work? Or is that impractical and may not hold a straight edge. Are there form setting systems out there that do this? I could have sworn I have seen smaller gaps before. BTW thanks for your time to answer these questions. This is the kind of stuff they didn't cover in two semesters of construction tech or Studios.

denni2579 Beautiful. Guess I'll have to custom make them as well since I doubt we will have that size. Thanks for the prompt reply, Richard.

Grounded - Richard Risner RLA, ASLA In the raised fire feature we used black lava rock (sometimes called cinder rock) the other black paving rock is called small black beach pebble. Try KRC rock or RCP block & brick.

denni2579 Many thanks, Richard and Motherbear.
Very helpful information.
