What's both green and platinum all over? Why it's the Margarido House, of course, which officially became the first house to receive the Leadership in Environmental Energy Design Platinum certification (the highest level possible) in Northern California this December. Homeowner and head of construction Mike McDonald (with help from Whirlpool) recently created a video tour of the property, filled with tons of information and great images of the home. And not ones to rest on their sustainably harvested laurels, McDonald Construction already has several other projects in the works, including a Mill Valley home that will be the second property to receive platinum certification in the area.
