When David and Sara Gottfried renovated their 1915 Craftsman bungalow three years ago, they became the owners of one of the greenest homes in America. Deemed LEED Platinum by the US Green Building Council, the modest but beautiful bungalow is a green dream inside and out.
As founder of the US and World Green Building Council, and creator of the LEED green building rating system, it's no wonder David Gottfried lives in a home that barely impacts the Earth. On the surface, the house looks much like the other well-kept Craftsman homes in Oakland's Rockridge district, a highly walkable neighborhood with coffee shops and European-style markets. But take a closer look at those lovely wooden steps leading up to the front door. They're constructed of redwood salvaged from the Old Sacramento Bridge. And that shimmering tile in the bathroom? It's all recycled glass. But this house's eco credentials go beyond aesthetics. Cracks and gaps from nearly a century of life have all been fully sealed, drafty windows all replaced, solar panels set up on the rooftops, and grey water systems installed.
David, Sara, and their two daughters moved from a much larger house in the nearby Berkeley Hills. To make their new home feel bigger, they enlisted the help of DSA Architects, a Berkeley firm that specializes in sustainable, green, and net-zero energy architecture, knocked down some walls, and opened up a cozy, stylish space where a family of four can flourish.
Furnished with timeless design classics that compliment the original Craftsman details, the warm interior opens out onto a welcoming oasis out back. David's "LifePod" office is surrounded by native California flora, the family's vegetable garden, and various spaces designed for gathering together and enjoying the fresh California air.
"This was a 30-year journey that began in solar engineering classes at Stanford," David said. "I’ve always wanted a deep green remodel, on steroids."
Our style: Eco-Craftsman that’s modern yet honors the Craftsman story. Crazy, deep green. We feel it is most green to rehab rather than to build new.
Inspiration: We love the sweet little bungalows of the Rockridge District, which is like a European hamlet – you can walk to get everything from organic produce to fine wine to locally-roasted Blue Bottle coffee to grass-fed beef. Our local coffeehouse, Cole Coffee, has people hanging out, socializing and connecting with new folks all hours of the day. We’ve met many of our friends there. We can retrofit the house well into our old age so why not go crazy with the green? Small is green.
Favorite Element: David - LifePod. As an engineer, the radiant solar hot water heating. Silent, incredibly efficient, extremely elegant.
Sara – I love the solar hot water radiators too but mostly because they’re so sculptural. We custom powder-coated each one to match our zero-VOC paint. I’d have to say the large lot, veggie and natural dye garden is my fave element.
Biggest Challenge: David – Cost! Not cost of green, but cost of custom renovation.
Sara – Getting my husband to sleep during the design and renovation phase. He is a green pioneer, and this project was a long-held dream for him. He’d stay up way past bedtime reviewing every LEED credit for how to take the house to the next level.
What Friends Say: "Pretty colors, so soothing." "Can’t believe your PG&E bill!" "Love the Craftsman detail" (David’s mom repeated this over and over when she thought we were making a huge mistake and she was trying to find something positive to say – see David’s second book on the house, Greening My Life).
Proudest DIY: Planting the garden, which we did as a family. There’s been a lot of trial and error, emphasis on the error. We also love our Rain Hogs. We got them used from a sustainable food conference in San Francisco. I love that they were a little banged up and had a productive life before we got them, rather than shiny and off-gassing new from Design Within Reach.
Biggest Indulgence: David – Connecting the grey water/rainwater to the toilets? Or the reclaimed redwood from the Old Sacramento Bridge that we turned into our front stairs at 3X the cost?
Sara – 32 paint colors throughout the house? My husband budgeted for 5 and thought he was being generous.
Best Advice: David - Everyone can go green. The key is to start.
Sara – You don’t have to sacrifice aesthetics for green. Nowadays, you can have green and gorgeous.
