Fire Island’s glass-encased Pyramid House has hit the market for $6.5m – a price tag reflecting its architectural significance and prime spot by the dunes.

The three-bedroom Fire Island home dates back to the 1960s and was originally designed by Argentinian architect Julio Kaufman. He positioned the coastal hideaway, so views of the National Seashore and Atlantic are best enjoyed from its great room (which also explains its pyramidal shape.)

In early 2006, the house got a significant update courtesy of architect Hal Hayes. He replaced its entire front wall with a bank of glass and reconfigured the interior so the top level is an open living-and-dining space with a kitchen, and the primary suite is on the lower level – all the better for drinking in the views.

The three-bedroom Pines property is listed with agents at Brown Harris Stevens, and its rooms are brimming with midcentury style. There’s plenty of space for guests, too, with an additional pair of pyramid-shaped cabana bedrooms on the other side of the pool.

Fire Island is something of an architectural playground, known for its modernist architecture and being a queer mecca. Consequently, Pyramid House offers pretty lucrative rental income – presently listed on Airbnb for over $3,000 per night during peak summer.
