Edwin,

I took a look at those sites. The first one had a nice video
explaining how it works, very interesting. I'm going to give them a
call for more info. I just wonder how they do plumbing and electrical,
especially after construction is done.

There is a sub-industry to provide the tools for working with those types of
materials. One is

I know they try to design the plumbing for interior walls and have a tree go
up that way. Electrical is doe with a cut out by a hot knife for the foam.

If I was building anew house today, I'g go with one of these methods.
Construction cost is very competitive with stick built and thee is savings
for years in energy.
