Mundy has had a hard life, but after many difficult years, he is rich and can afford to build a house for himself. He wants it to look just like a plantation house he used to see as a child growing up in Georgia. Mundy used to think of the plantation house as being grand and unattainable, and so wants to own it, now that he can afford it. Roark tells him that he’d then be building a monument to other people rather than to himself, and so he refuses to build it.
