The project consisted of two sections: the three-story residence (completed in November of 2010) and a three-level carriage house (a 9,000-square-foot concrete, masonry, precast and steel structure completed in May of 2013) with a 120-foot glass and timber bridge connecting the two buildings. The bridge starts at the back yard of the residence and ends on the upper deck of the carriage house where there is a pool, covered exterior kitchen, and dining and lounge area that offers stunning views. The lower level of the carriage house incorporates an eight-car garage, workshop and a basketball/racquetball court that incorporates an adjustable basketball hoop with remote operation. The intermediate level houses a lounge, restroom, shower, and the mechanical and pool equipment rooms.
Friede & Associates worked closely with Steve Shulfer of Shulfer Architects and his team of consultants to skillfully carry out the design documents while incorporating the owner’s required aesthetic and functional elements. Friede self-performed the concrete, wood framing and finish carpentry work.
The location created several challenges—excavating and building in glacial till, steep and restricted access and tight work spaces. Difficulties to overcome during construction were numerous, as construction of the residence began in November with a snowy and wet winter. Access was by a tightly winding road rising 120 feet from the street to the house site making general accessibility, deliveries of equipment, precast and trusses quite challenging. The glacial till subgrade was prone to sloughing and contained random boulders and rocks. The hillside grades and slopes along with the owner’s desire to keep as many trees as feasible minimized access around both the residence and carriage house for construction.
In addition, the slopes and subsoil materials made placement of traditional footings and piers nearly impossible for support of the bridge. Helical piers were placed from both above and below the bridge location utilizing articulating arm lifts with specialized heads. This allowed placement of the supports without any excavation or disturbance to the hillside. Engineering the perfect plan also required a balancing act between daylight and scenery. Number, size and locations of windows were determined to maintain views, while minimizing solar gain and heat loss. Solatubes were incorporated to maintain the home’s light and airy interior as well as reducing the electrical usage.
The structural requirements of supporting a full-size pool called for large structural masonry, steel and precast concrete components and with limited space, required careful planning and execution. The heating and cooling system combines the advantages of both geothermal and wood. Heating is distributed with in-floor heating and cooling through a high pressure system. Even with heated sidewalks and garage approaches, the cost of operating this system in the residence, including the electricity, is only $300-$400 per month.
In The End:
This highly-detailed project resulted in owners who are greatly appreciative and who proudly show off their home to family, friends and associates. For Friede, that, along with winning a coveted Project of Distinction Award, illustrate to us that we did our job right.
