A screened-in porch was a must-have for the residents (they love to sit outside but hate mosquitoes) and influenced the building's asymmetrical shape. "The question became how can we integrate this into the design of a modern house," says architect Staffan Svenson. "Can it be a screen porch without looking like one?" He devised a plan to hang a horizontal louver system from the structure to give the illusion that the powder-coated steel fins hover in place. He used the same material for the guard rail on the second story.
