West Chester Leed House - new local build

This new home project from my local practice may be the first project to use a variation on the USA New Wall. But even if it does not we are vetting a number of interesting tech here and it should be fun to watch.

This is not a modern styled house, so no eye candy for our modern house following, but there will be lots of interesting tech and well worth watching the build. Even though the house has a craftsman style feel to the exterior, the floor plan is very modern, open plan, to accommodate contemporary living. And as the name suggests it will be Leed Certified.

This house is utilizing Superior Walls, a precast, and pre insulated basement wall product. This allowed the basement to be installed in one day - no concrete formwork and much abbreviated prep time. Rather than a conventional footing and fragile, relatively speaking, basement wall, the precast wall is very strong and stiff and only requires a stone bed beneath it. This stone bed spreads the load out to meet the undisturbed soil at with a load pressure within its bearing capacity, and this is how it precludes conventional footings.

We are encouraging the use of Mineral Wool in a USA New Wall Better Wall configuration. It may instead use foam and blown in cellulose, but still in the Better Wall configuration. In case you are curious this will not be using Swedish Platform framing, rather conventional western platform framing is being used. But the Better Wall configuration with an exterior insulation layer does improve the thermal bridges inherent in western platform frame.

Our client Intersect Homes is the owner/builder of this project, so we have a build dedicated to building green. Slide show below after the jump to get more of a feel for this project as it starts.
