We recently moved from San Francisco to Mill Valley so that our kids could grow up a bit closer to nature. With the recent stay-at-home orders in place, we had plenty of free weekend time for home projects. Plus, we could all use a little more play in our lives these days 🤗.
As a starting point, most sandboxes aren't very good looking. Most tend to break. So we took at little time to think about what makes a good sandbox and built one. Below is some of the thinking that went into it and a few pictures of the process.
I never thought I'd write design principles for a sandbox, but this was kinda fun.
Most sandboxes break after a year or so. By contrast, the structure should be
enough to withstand two rambunctious boys and their friends. The last thing I want to do is make something that breaks a year from now. Hopefully it lives up to this principle but time will tell :)
One simple observations from years of watching my kids play in sandboxes is that size plays a key role in how kids play together, or don't.
If the structure is too small, kids don't convene and play together the sandbox. In contrast to small mail-order sandboxes, one example that I had in mind was the gravel pit area at the
. My kids love this area. It huge and draws kids into the communal experience of moving gravel in a striking and almost comedic way.
So the idea was to make the sandbox large enough to be
for kids, but not too large that it didn't fit the context of the yard.
One thing that always strikes me about plastic sandboxes in backyards is how they stand out from the nature around them. Often there are lots of trees and grass, and then, 💥 a giant piece of plastic.
So it was important to me that the structure fit with the
of the house and surrounding yard. In practice, this meant making it out of redwood and painting it the same color as the trim on our house.
Six foot by six foot square. Large enough to fit 2-3 small kids at one time.
A six foot by six foot sandbox requires 24 bags of 50 pound sand.
3 inch rim provides a place for adults to sit on the side of the sandbox.
Side boards (Redwood)
6 foot boards → 1 by 8 inch
Note: actual width is between 7.25 and 7.5 inches
Interior posts (Redwood)
15 inch posts → 4 by 4 inch
Top rim (Redwood)
Six foot boards → 1 by 3 inch
Note: you'll need to cut ~3 inches off of two of the boards
