In the short story "Shiloh" by Bobbie Ann Mason, Leroy is a truck driver who got injured in an accident and can't drive anymore. Instead of being out on the road constantly, he is home full time with Norma Jean, his wife. It seems that when he spent long stretches of time on the road, it dissipated the tensions between them, which are mainly due to the tragedy of the death of their son when he was still a baby. Now that Leroy is always at home, they have become uncomfortable with each other.

Early in the story, the author reveals several reasons for Leroy wanting to build a log cabin. He wants to offer Norma Jean a real home, a home of their own instead of a rental house. He figures that a log cabin would be less expensive to build than a more traditional type of home. He is also learning to put things together, so he passes the time by constructing model log cabins from Popsicle sticks and Lincoln Logs. As revealed at the end of the story, however, the real reason he wants to build a log cabin is to save his marriage. He realizes the futility of the idea after Norma Jean says that she wants to leave him.

Norma Jean makes it clear from the beginning what she thinks about his log-cabin plans. She doesn't like them, and she doesn't want to live in a log cabin. She doesn't think that the local subdivisions would even allow log-cabin construction. She is skeptical, derisive, and doubtful. She sees his efforts to learn about log cabins as frivolous and useless as the classes she takes at the local community college. Her rejection of his plans is symbolic of her rejection of Leroy and of her desire to leave him.

In Bobbie Ann Mason's "Shiloh," how does Norma Jean feel about Leroy's plan to build a log cabin?

"Shiloh" is a short story by Bobbie Ann Mason, collected in her 1982 anthology Shiloh and Other Stories.

Leroy, who is unable to work as a trucker because of an injury, has a vague plan to build a proper log cabin for Norma Jean, his wife. His plan comes from his hobby of building model kits; he has no other work, and so talks about his future plans without making any steps towards realizing them.

Ever since they were married, he has promised Norma Jean he would build her a new home one day. They have always rented, and the house they live in is small and nondescript.
...
[Norma Jean says] "I don't want to live in any log cabin."

"It's not a cabin. It's a house."

"I don't care. It looks like a cabin."

"You and me together could lift those logs. It's just like lifting weights."

Norma Jean doesn't answer.
(Mason, "Shiloh," Google Books)

At the end of the story, Leroy realizes that his plan has flaws; he wants to build her a house without any idea of how much work it entails or what is inside it. Norma Jean can see that Leroy's model house is just a framework, with no substance to make it a home, like his attitude towards their marriage; in her eyes, the plan to build the log cabin is as immaterial as his concern for her well-being. She doesn't want a husband who only cares about superficial things without addressing her emotional core, and sees the log cabin as a representation of how little thought he puts into their marriage.
