Three Philly mansions that let the sun shine in

In the weeks immediately following daylight saving time, sunlight seems even more precious. Fall's golden light lingers less, but somehow feels more vibrant. While real estate listings are lousy with exaggerations about "light-filled spaces" and other bright rooms, these three million-dollar-plus homes feature seriously impressive walls of windows and other avenues to let in the final days of glorious autumn sun.

8520 Hagys Mill Road, Unit C, Philadelphia
$2,850,000
Monthly taxes: $834
Tell me all about it: Calling this five-bedroom unit a condo almost seems unfair. It doesn't quite evoke the coziness – or the expansiveness – of this specific home. We love that the home includes multiple seating areas adjacent to walls of custom windows. The home includes a sun room as well as a sort of bonus living space that includes its own private entrance and triple-paned windows. Oversized windows with sashes abound.

31 Summit St., Philadelphia
$1,375,000
Monthly taxes: $1,019
Tell me all about it: This handsome, seven-bedroom Chestnut Hill estate includes original stained glass windows, large bay windows and our favorite style of mullions. The show-stopper here, though, is a solarium on the first floor. It is independently fantastic, and it also adjoins a deck and overlooks the grounds, which have been designed as a "certified wildlife habitat" in the neighborhood.

609 W. Gravers Lane, Philadelphia
$1,695,000
Monthly taxes: $1,822
Tell me all about it: It's hard to imagine a better setting for so many windows. This five-bedroom Chestnut Hill home is situated on two acres between Fairmount Park and the Philadelphia Cricket Club. It includes multiple banks of oversized windows and several two-story window walls that seem to fill the home with light. The light is abundant everywhere but the lower level, which makes it an even better media room.
