Sensitivity to site conditions and surrounding environments

  • Building covenants restricted size
  • 4 story house, suite on lowest level
  • Siting optimized for infill lot
  • Engineering for shear wall/lateral load requirement
  • Conforming space covenant required garage separation
  • Site conditions challenging, lot slopes 2 directions
  • 1 side 2 story basement, other fully day-lighted /walk out third floor to natural grade
  • Upper deck elevation connects to garden
  • Modeling determined lower pitch roof for solar panels/snow load
  • Client noted that PV panels overproduce based on modeling
  • Site line of solar panels not seen from street scape

Selection of materials and resources

  • 6.5” SIP panel walls with insulated 2x4 wall inside= effective R30 wall
  • 12” SIP panel roof/R48 + 1.5 XPS insulation on underside to create thermal bridging = effective R57 roof
  • 10 kw photovoltaic solar panels
  • Exterior 2X4 wall used as mechanical chase to enhance HRV performance in challenging open concept design
  • High efficiency wood fire place right sized to house
  • Smart panel enables computer dash board displaying household energy use, integration of PV array , EV charging station

Energy and water saving considerations

  • Net zero designed home
  • South facing Solar panels
  • Large overhang shields sun in summer/allows passive gains in winter
  • EGNH 87
  • 1.5 ACH
  • Energy Star Triple glaze windows
  • Rain barrel

Construction practices and details of certification program chosen

  • Built Green Platinum
  • Air tight under 1.5 ACH construction
  • Passive solar design, high effective R values
  • Optimized HRV ensuring healthy home
  • Year round comfort, ventilation/passive solar/solar captured strategic roof overhangs

Innovation and design

  • Lower level entrance sheltered by upper floor deck
  • Porcelain tile floors, large storage closets enhance entrance area
  • 2 guestrooms shared bath, den, mechanical/laundry room also on lower floor
  • Engineered timber open riser stairs, glass panel railing connects all four floors allowing daylight to bottom floor  
  • Second floor contains great-room concept living area, children’s rooms and kitchen with access to large deck at front of house
  • Sleek modern kitchen has grey, grained 360 degree wrap doors, touch latches, Ceasarstone tops, under-mount sink, large island with eating bar and waterfall edge on island top,
  • Third floor contains master ensuite with private roof top patio

Concept that created the inspiration for this innovative feature

  •  Main floor of house is open concept with no interior walls and large window areas.
  • The combination of bedroom floor above, snow load and seismic engineering design requirements were challenging
  • Design required additional lateral bracing to meet engineering design standards
  • The only wall area available for additional lateral brace walls was the stair well. To maintain site lines through architecturally designed stairs, the turnbuckle application was designed to replace the conventional solid shear wall that would have been required
  • Innovative concept was low cost and added to architectural appeal
  • This application is low cost and transferrable to other projects

Unique design elements

  •  Maintains site lines
  • Visually appealing
  • Enables larger area of glazing to take advantage of natural daylight capture maximizing solar gains from winter sun reducing winter heating loads

Choice of materials

  •  Turnbuckle logical solution other than solid shear wall
  • Adjustable cable design easy to install and relatively low cost
  • Easily transferable to other sites
  • Ties in well to timber frame and overall architectural design of house
