A quote from an old carpentry book.

[onethatcares]

7. first building code

"If a man builds a house for another man and that house falls down, the builder shall be killed"

Second building code

"A man that builds a house without first knowing the cost is a fool"

I don't know who to ascribe them to, Sorry.

When starting out in the carpentry field 60 years ago I leaned on a book titled, "Wood structures for permanence". I wish I still had it.
