I too have lusted over the Neutra numbers on DWR, but again, $75 each….enter research mode.

WestOn Letters’ (link below) website provides my numbers at a budget price -I choose “deep ribbon” with spacers.  Cost about $85 for all 3.  I sketch out my vision of simplicity to be translated by my crafty counterpart into real measurements.  Wood, deck stain, gravel brought the grand total up to about $125.

Pressure treated dog eared fence pickets screwed together on a frame with stainless steel screws.  He cut the curve for the mailbox with a reciprocating saw and built a platform within the column for the mailbox to sit. We used our old mailbox so that cost is not included in our budget.  Gravel at the base serves 2 purposes – keeps the look minimalist, but also keeps the wood off the dirt so it won’t rot, despite being pressure treated.  We put a sheet of plastic under the gravel as well as an additional moisture barrier.  The roof between the side walls is pitched at a slant  (shed roof) for water runoff.

Found the mossy stones in my yard to finish the look and voila!
