Making the most of Ramsey County's compact lots
St. Paul lots are narrow, close, and full of character, which makes outdoor projects a design problem worth solving well. The classic Ramsey County moves are a back deck that squeezes real living space from a small yard, a front porch that matches a 1920s facade, and additions that thread city setback rules.
A builder who works these neighborhoods designs to the lot instead of against it and knows what St. Paul and the inner suburbs require on paper. You get outdoor space that fits the house and the block, with the permit file done properly.
