Green Cabin Design Winthrop

1400 SF

Project Description

A 1,400 square foot cabin located in the mountains of North-central Washington State. The cabin sits on a south facing slope with views to the south and east. The materials selected for the cabin, logs,  sawn beams,  rough formed concrete and corrugated metal, are rough in nature to reflect the natural but untamed setting. Two concrete walls form terraces on which the 2 level house sits. The lower terrace contains the living, dining and kitchen all as one large space. The upper concrete wall forms the back of the living area and creates a base for the upper terrace which contains 2 bedrooms and a bath. Two eight foot by eight foot sliding glass doors on the south side of the lower level opens the house to the outdoors. To further connect the house with the outside, all of the rooms have doors that open to the outside, including the bath, which opens to an outdoor bath for use in the summer months.

 

Energy Conservation

It is designed to take advantage of passive solar heating. The majority of the high performance glazing faces either south or east. The east facing glazing was provided to allow for morning warming; even in summer, nighttime lows often reach the 30’s. Large amount of thermal mass was designed into the house to reduce diurnal temperature fluctuations both in the summer and the winter. This includes an exposed concrete floor and a rough wood formed concrete wall that serves as a retaining wall between the upper and lower floors. The roof is insulated to R-50 and the walls to R-23.These factors combine to reduce energy use significantly below code requirements even with a large amount of glass.

 

Sustainability

Significant attention was given to material selection for the house. The house is sided with wood that was salvaged from a water irrigation ditch. The 2x12’s have naturally weathered over the last 60 years. They were cleaned and sealed when the were installed.  Hopefully, they will go another 60 years with out much maintenance.  In addition, the roof purlins are Lodge Pole Pine logs that are from forest thinning. Much of the rest of the wood in the structure is “processed’ wood. This includes: glue-lam beams; rough sawn plywood used for ceiling and wall finish; exposed paralams for stair treads;  I joists and paralams used for structure.  The fixed areas of the window walls were framed with hand selected framing lumber. Additionally the cabinets and doors were constructed with veneered woods. The use of interior plaster walls with integral color virtually eliminated the need for interior paint and are much more durable than gypsum board walls.
