The past week or so has been a bit stressful. There’s been a ton of engineering coordination, like I referenced last week, and this has impacted the work that was happening on site. All is well–and we needed to break ground if we want to get dried in by winter–but it was certainly time consuming.

But all stress aside, some very cool details were finalized last week. One of the items K and I are most excited about is how the brackets and posts that support the roof have come together. I know, this is a nerdy thing, but they’re going to be stunning.

I’ve included a couple of screenshots below, but we have two types of support systems. The “y” columns are made from douglas fir glulams, and lean back at a 5 degree angle (roughly) so they meet a pair of bigger glulams that then support the roof. You can see this in the image from this post.

There are some very trick, but simple, details in this system.

Our friendly engineers insisted on upping the amount of steel in the brackets. This is because we have a 5,000+ s.f. roof, coverering a 2,200 s.f. house and 600 s.f. garage. It’s a big roof, and it faces a windy meadow. So there’s a lot going on with the roof in terms of load. Eastern Washington also gets a lot of snow, so there’s that, too.

Back to the brackets. You’ll see this in the picture, but we’ll have  1/2 inch steel plate mortised into the wood. This plate then extends, like meat in a sandwich, between two 16 inch tall glulam beams. The reveal–the gap the steel will create between the two beams–is going to be pretty trick. Check out the “Point House” image below, which shows a nice reveal detail. Then at the base, a similarly beefy bracket will get bolted to a separate “marriage” bracket that supports the bottom of the “y” column.

Originally this was going to be a much lighter look. But the heavily articulated robocopness (yes, I just made up a word) will be cool too. And I think we’re going to galvanize the steel, which should lighten things up visually.

The other brackets are much more subtle. Steel pipe that shares a similar kind of bracket detail, but it’s much simpler.

Combined, the two styles of posts and brackets will create a pleasing contrast, I think.

There’s also an upside to Matt’s design when it comes to making the brackets. Our friend Smitty, or Sean Smith, is fabricating these for us. But because the bracket system is primarily made of of individual pieces of steel, most of the “work” will be done by a CNC laser cutter. This makes things fast and relatively inexpensive.
