This Darnestown addition is a showcase of innovative green building products and techniques.  Take a look at the photos below, or view the project as a slideshow!

Details about this Award Winning Remodel:

We designed and built a three story addition to the south facing side of this Darnestown, MD home.  The addition included a total of 1747 square feet of new space to extend two children’s bedrooms, add a bathroom, a sunny and semi enclosed family room and an indoor pool.  We also remodeled the existing deck and added a screen porch to create a comfortable, mosquito free, outdoor seating area.  We used green building materials and techniques wherever possible.

It was important to create more living space, and address the aspect of energy efficiency we were interested in achieving.  The entire addition is super insulated. Two-inch thick Styrofoam was set beneath the entire concrete floor of the addition’s lowest level.  2.5 inch thick, R12 Styrofoam blocks were spaced, positioned parallel to one another, and filled with concrete to create insulated concrete forms on the lower level, giving the wall an R22 rating.  The top two stories were built using 2×6′s, instead of 2×4’s and sheathed with structural insulated sheathing.  1 inch of spray foam was applied and fiberglass insulation was installed for a total wall rating of R30.  Three feet of fiberglass insulation was blown in the attic for an R value of R78.  The entire home is now heated and cooled with two geothermal HVAC systems powered  by three 450 feet deep wells, drilled in the front yard.  We also added solar photovoltaic cells to the roof.

Inside of the addition, we used a number of green, recycled and re-purposed materials, including a refurbished antique fireplace mantle in the family room on the middle level, a Heat-N-Glo fireplace with insulated doors and outside air inlet.  We used bamboo flooring in the kids’ bedrooms on the top level, a dual flush toilet, and CFL and LED lighting.  We also designed the pool area with energy efficiency in mind.  With two French door entry ways, the area is closed off from the rest of the basement. We used clefted Indian slate flooring in the pool room to prevent slipping.  The pool and spa can be covered for safety and to retain heat.

Although it was important for us to incorporate green materials and processes wherever possible, we made an effort to make sure the green aspects were also functional.  On the middle level, the addition can be entered through the existing living room.  The area has an open, yet separate feel, which establishes a level of continuity between the spaces, but also creates a quiet room away from the hustle and bustle of the rest of the house.  Energy Star, low e aluminum clad Pella windows with argon filled glass, fill the space (and the entire addition).  This provides as much natural light as possible into the family and pool rooms, without raising energy costs. The fireplace also serves as an alternate heating source that will warm the family room during the cold winter months, and keep the energy bill lower.

The family room fireplace mantle was used as inspiration for the choice of crown molding and custom cabinetry.  We replicated the dental pattern of the mantle for the crown molding and used a rope detailing for the media cabinet.  Exotic onyx tile was selected for the fireplace hearth and cabinet countertop.   Pebble stone tiles were used for flooring in the new bathroom on the top level, to create a “walk in the woods” feel.  Tray ceilings were designed for the two bedrooms creating an open look.  We also laid brick to finish the exterior of the addition.  This not only improved the look of the home as a whole, but it is a more green and durable option to vinyl siding.

On the deck, we replaced the weather damaged top rail and overlaid the deck with Azek.  This way we blended the new PVC with the existing wood for a visually seamless appearance.

We increased the size of this home by about a third AND lowered utility costs by about a third!

In December 2011, this project won the Montgomery County Builders Association Award for Best Addition over $250,000.00.

In January 2012, we won the National Association of Remodeling Industry’s Contractor of the Year award for “Green Remodeling Entire House”.
