Q: How big of a hogan can a person build using our brackets?
A: The largest built so far is 40' in diameter (Chinle, Arizona) shown in the pictures. However, if there is no snow load at your location a person could build one with a larger diameter. It could be built with truss joist rafters, although it hasn't been designed yet. In any case, the building needs walls to support the beams at ceiling level between the corners. The areas would be 1236 s.f. for a 40' diameter and 1931 s.f. for a 50' diameter.
Q: Hello, I've been looking at your bracket kits and was wondering if you plan on (or have available) brackets for wall timbers larger than 4"x4"? I would like a beefier wall both from the standpoint of insulation, and point load at rafter ends. Ideally I would like a 6"x6" or 8"x8" timber for the walls since I would likely go with the 30ft diameter hogan design. Let me know. Very interesting product and concept.
A: Hi, thanks for the inquiry. About the corner posts, when we first started doing this, I thought about going up to 6x6's for larger structures, but never went there because I never felt the need to do so. For example, one family in Shiprock built a 30' diameter two-story frame with the brackets and made 2x6 tilt-up walls and put them in place around the perimeter, addressing both the insulation and support issues. I agree that support must be provided between the corners, and except for gazebos, that's what we tell people. By the way, the 4x4 posts will support about 4000 lbs each, add that to the stud walls and even 2x4 walls do the job structurally. That said, the customer is always right and we can make them for other sizes. Figure on 50% higher price (we'll do better if we can). I agree that the 4x4 frame does look spindly for the larger sizes, but once all those rafters are in place tying everything together, it is very rigid.
Q: How many brackets are there?
A: There are 17 in total.
Q: What do I get for the price of $1550+?
A: You get the 17 brackets plus the hardware (lag bolts, bolts, and nuts) to attach the brackets to the 4x4s and 2x lumber that you provide, and assembly instructions.
