A good house in a good neighborhood of 1920s homes and mature trees, two blocks from the Mississippi River in St. Paul: “It was a perfect size for us, about 1,700 square feet,” says Sandy, one of the owners. They hoped to “put the bungalow back” in period style while adapting the house for modern life. At first they expected that work would be mostly cosmetic. The staircase was closed and in the middle of the small house, where it impeded circulation. Moving it gave them extra space, yet the project was cheaper than an addition.
