It looks small in front, but the four levels at 575 28th St evidently span 4,090 square feet. The 5-bed, 4-bath Noe Valley house was built in 1980 and renovated between 2007 and 2008 — after being sold in 2007 for $1,495,000. What to do with so much square footage? Put an "enormous playroom" on the first floor, apparently, and build a wine cellar (and stage it with a wall-facing desk). The house has two decks, and a spiral staircase connects every level to the yard out back. Asking price today: $2,250,000.
