New hybrid timber frame/double stud wall home 6

Lots of outdoor work lately.  We've completed the deck and porch framing and finish.  We framed the deck with galvanized steel joists, which are strong, fast (they're pre-cut), straight, and won't warp like large section PT lumber.  The decking will be thermally modified ash from western Mass.  The porch and deck roof is painted tongue and groove 2x6 over native cherry rafters.  The hips over the deck are irregular (meaning that they are not 45 degrees in plan view), so the jack cuts are different on each side.

We had a preliminary blower door test at the house, before the insulation (dense-pack cellulose) was complete.  The blower door is a very direct measure of how air tight the house is.  We had a great preliminary number of 465 cfm or 0.58 ACH50 (air changes per hour at 50 pascals pressure difference).  That's pretty impressive with 48 windows in the house, and beats the incredibly stringent Passive House standard of 0.6ACH50.  

I also put some pictures in of the elliptical ceiling in the upstairs hall.  We made ribs of 12' MDF, and sheathed it in 1/4 plywood.  We very slowly bent 1/2" sheetrock to the radius (they don't make 1/4" that long).  The ellipse comes in tangent to the wall surface, so it blends in perfectly.

Lots of activity on the job.  Framing is complete.  The interior air barrier (Intello) and service cavity are complete.  The entire house is off of the electric grid, so we're running all of our tools off of PV.  Dense-pack cellulose in the 12" double stud walls and 18" cathedral ceilings is complete.  And windows and doors are in.  While the sheetrock is being done, we'll be outside starting the south porch and west deck.

Lots of progress on the hybrid timber frame we've been working on it Becket.  In one quick week, we put the timber frame up, the floor panels from Bensonwood, the second floor wall, and the roof purlins. You can see some of the big 7x18 gluelams that spread the roof load to the outer walls.
