Organisms with complex macrostructural construction abilities
have rather slow doubling times. If you want to look at a house-
builder, the appropriate model is a tree, with doubling times in
years or decades. Further, we're a very long way from
enigneering trees to grow particular shapes. And think how
long it will take to test it! :-)

You have to define "designer". I can make a bacteria
to do certain things for far less than that, but only
a few particular limited things. If you mean a bacteria
which can build a house, you're on.
