WASTE NOT, WANT MORE

The homeowners demonstrated their dedication to sustainability
and conservation in several other ways. While their home was
gutted during renovation, original oak flooring and brick veneer
were salvaged for reuse in the project. High albedo (reflective) metal
roofing was installed to reflect solar rays away from the home,
helping to keep the interior cool. In addition, materials with low- or
no-volatile organic compounds (VOCs) were used in the renovations
and finishes throughout the house.

At the homeowners’ request, extensive glass was added to the
house wherever possible to allow maximum amounts of natural light
in, reducing the need for electric lighting during daytime. When the
sun sets and natural lighting is no longer an option, the homeowners
illuminate their interior with LED lamps.

The windows also offer unique views of the large, wooded
property’s unusually deep slope. As avid gardeners, the homeowners
wanted to highlight their gardens, so a deck was added off of the main
living area facing the landscape to provide the best views possible.

Thanks to Atlanta’s mild climate, the deck also serves as a
