Designed by prolific modernist legend and one-time Simpsons reference Richard Neutra, the Pitcairn House enjoys a few perks that Neutra's urban designs forego; complete privacy, for one, and through floor-to-ceiling panes of glass, a front-row-center view of the changing seasons. Listed as "the quintessential house in the woods," this stone-clad mid-century modern sits on 10 acres of Bryn Athyn, Pa. forest, surrounded by the 812 conserved acres that make up the Pennypack Ecological Restoration Trust. Large triangular trusses span the length of the interior, extending outside to form overhangs covering the large deck and courtyard terrace. The inside looks straight out of 1962, the year it was finished—fans who winced when Neutra's Cyclorama was lost and rushed to save the Connell House can breath easy on that front—although the bathrooms were renovated in 2000, and a "professional video editing and screening room with a sound-proof recording studio" was added to the lower level. Look over the home, just listed for $6M, in the gallery below, and be sure to take note of the mean spiral staircase in the living room and the swim-in-place pool underneath.
