Very impressive.
We are in the planning process (as you may recall) for our home build. I've had several conversations with Chris at Clydesdale.
We are looking at something similar in design - really a one story with a small knee wall for the loft area over the kitchen and front entry areas of the house.
Two specific questions at the moment.
1) What pitch do you have for the roof over the living/loft areas? We have been using 8:12 in the floor plan software, but I have a slight headroom problem when exiting onto the loft. I can fix that by either increasing the pitch, increasing the loft kneewall height, or changing the orientation of the last span of stair run by 90 degrees.
2) Regarding your 3T GSHP. Do you distribute the heat for the basement and first floor with in-floor tubing (i.e. hydronic heating), straight to forced air, or some combination?
Thanks.

Yep talked with Chris the other day - he is great to work with
Main pitch is 8:12 in our 3 bent great room
other areas are 4:12 for shed style roof over MBr, porch and pantry
we initially started with a 4' knee wall but to gain access into the bonus room we raised it to 8' knee wall (was minimal extra cost - SIP and siding primarily) really opens up the area in the loft as well as volume over great room (although it would have been there at 4' also)
If you go with taller pitch and use SIPs think about total span - I think they could go 24' and in my case I wanted as few joints as possible
For the basement and 1st floor we have 2 zone forced air - it was very easy to run this duct work.
We had spent a fair amount of time working on radiant or duct and in the end it was cost decision and realization that my heating load is relatively small for most of the year (even with current temps and little sun the unit runs about 30% of time overnight then rarely during the day as my south windows provide plenty of heat)
The duct work was free (needed it for summer cooling) and radiant was ~$8k for distribution tubing, and $2k more on unit for water heating
We were trying to hit a budget and by the time this decision had to be finalized we were already aware we were going to go over
On budget as you work with Chris - I found that cost is control is primarily related to number of joints in your frame - reduce as possible. This led to the 3 bent design with 16' and 20' spans then the shed roof over MBr
Similar to what jk96 did you can also remove TF in areas that are less "exposed" and in general remove rooms you don't need
