In the Nest House, how was subflooring secured?

Secured using construction adhesive perpendicular to the joists and 8D nails / deck screws

In the nest house, how are the joints in the plywood arranged?

Staggered

What is the most important in avoiding squeaky floors?

Must properly fasten the subfloor to the joists

What is used to properly fasten the subfloor to the joists?

Nails or screws 12“ on center in the field of plywood and 8” on the edges

What is one main difference between the traditional practice and framing efficiency of where walls meet

Traditional practice = creates “U” that is hard to insulate
