It doesn't look too difficult to make if you have reasonable carpentry skills. You can make it to fit either EarthBoxes or DIY tote box SIPs.
I'm wondering if the SIPs are too close together as shown. Obviously you could install fewer SIPs.
You can rotate the sketch in 3-D on the site. Have a look.
