The Winding Brook Road project is featured in a book that will be published this spring, "Prefabulous + Sustainable" by Sheri Koones. This is a well-written and timely book with interesting projects and great photography (Eric Roth photographed the Winding Brook Road house among others). The publisher is Abrams Books. As Robert Redford writes in the forward, "Prefabulous and Sustainable will inspire you to consider more environmentally friendly options and show you how to create homes that will bring balance to our future."
Here's a photo of the staircase in my Winding Brook Road house. The stair treads and stringers are LSL (laminated strand lumber). LSL's are generally used as construction grade framing members and are not typically left exposed. I have found that when they are sanded and finished with an oil or urethane they have a beautiful and distinctive appearance. They are initially very rough and require a lot of sanding, but they are also very dense and strong (and therefore durable). The posts and railings for this stair are solid cherry, fabricated by a friend and colleague, Ruud Vekemans. The cables are 3/16" diameter stainless steel with simple and elegant tensioning hardware at the post connections. The outside wall of the stair tilts outward at the top and has a 20' tall insulated translucent window panel, manufactured by Kalwall. Natural light filters through the Kalwall and through the open stair into all levels of the house. At the top of the Kalwall panel there are two hopper windows that are left open from April to October. These windows in this tall open stairwell provide a natural chimney that vents warm air out of the house during the summer months. There is a ceiling fan that pulls air upward which assists this natural venting.
Here is a photograph showing the entry details. The vertical grain fir paneling matches the wood of the entry door (manufactured by Simpson) and creates an inviting entry to the house. The fir paneling folds out at a point that lines up with the bottom of the window sill and then projects horizontally to become a bench. The bench is supported by a powder-coated steel frame which is bolted to the wall behind the fir. The steps are made from slats of Cambera that are held together by stainless steel threaded rod.
