The Folly by Ivan Vladislavic

A vacant patch of South African veld next to the comfortable, complacent Malgas household has been taken over by a mysterious, eccentric figure with "a plan." Fashioning his tools out of recycled garbage, the stranger enlists Malgas's help in clearing the land and planning his mansion. Slowly but inevitably, the stranger's charm and the novel's richly inventive language draws Malgas into "the plan" and he sees, feels and moves into the new building. Then, just as remorselessly, all that seemed solid begins to melt back into air.
