2002 w. Lake of the Isles Parkway, Minneapolis, MN

Having been well preserved for nearly 70 years, this 1899 home, overlooking a lake in the heart of the city, was looking for a fresh 21st century update. While the owners loved the house, they saw lots of potential to make things just perfect.

The whole-house renovation features a super-green design for modern living balanced with a strong respect for the history and character of the home. All of the mechanical, electrical and plumbing systems are new. All siding and sheathing was removed and replaced, allowing new foam insulation to be applied from the exterior, thus preserving select interior finishes.

Almost all of the spaces in the house were remodeled in some way—taking a great house and making it better.

Two existing areas received special focus: the kitchen and central stair. The owners are gourmet chefs who do a lot of entertaining. A small but strategic kitchen addition allows an expanded and modernized kitchen with every amenity and expansive views of the lake and side yard. A new southeast-facing breakfast nook provides a cozy alternative to the remodeled historic dining room.

The existing central stair was very tight and awkward in places. To create a spacious and beautiful new stair, the center of the home
was demolished, roof reframed and center hall topped with a large skylight spilling light all the way down to the main floor.

A new outbuilding was constructed to house the owner’s workshop and a new 2-car garage. This “carriage house,” which is designed to echo the historic proportions and detailing of the main house, is linked to the house through a tunnel beneath the yard.

A welcoming, open front porch was built with lake views and a low-slope green roof.

Green Strategies:

The project earned Gold-level MN GreenStar certification by employing dozens of sustainable strategies, including:

• On Site Energy. 13 wells beneath the garden provide highly efficient geothermal heating and cooling, and a 2.2 kilowatt rooftop solar array offsets electrical loads.

• Energy efficiency. The building envelope was made airtight and reinsulated to Energy Star levels; all windows are reconditioned or new.

• Resource efficiency. Advanced framing techniques reduce lumber required. All lumber used is certified by the Forest Stewardship Council.

• Healthy Air. Energy Recovery Ventilator provides fresh air exchange while saving energy. Low/No VOC paints throughout. Radon capture system installed beneath basement slab. New cladding with rainscreen detailing helps prevents mold from moisture intrusion.

• Site & Community. Green roofs capture rainwater on site while reducing heating/cooling loads. All material reused if possible; all possible construction waste was recycled, including concrete, wood, and asphalt shingles

The purpose of this project was to update a 1913 Federal meets Prairie style home in Minnesota. The home suffered from poor flow and a lack of bedrooms and bathrooms. The kitchen had been remodeled in the 80’s to an all-white melamine which didn’t match anything in the house and was cramped and confining.

The homeowner wanted to be respectful of the original architecture and period of the home while adding some personal elements to the home. Design that accommodated both family living and gatherings of friends was a requirement.

An addition was placed on the back of the home on both floors to resolve the home’s many flow issues. It houses the new library, kitchen, bedroom, and yoga-room. It is now possible to circumambulate the home on both floors which greatly enhances the rhythm of the space both on the interior and the exterior.

A new metal roof, sand-float finish traditional stucco, rain-barrels, and extensive landscaping make the exterior of this home as classy as the interior. The lines of the addition greatly enhance the architecture of the home and the lines of the patio create natural flow around the home.

The home is now heated with a geothermal system, captures 40% of the stormwater from the roof for use in irrigation, and achieves a 95+% stormwater retention on site. Plantings are all drought tolerant or native, and the grass is a no-mow blend that needs little to no irrigation or mowing. All of the finishes were low or no VOC. Furnishings and fabrics are made from 100% organic or 100% recycled materials and are low VOC. Furniture is made using FSC certified wood, and many materials including doors, countertops, flooring, millwork and the entire patio were made from salvaged materials.

From the Homeowner:
“[The remodeler] managed to design the house to meet all of these specifications, without adding a lot of square footage which would have eaten up more of the backyard than I wanted.”

“Changes to the plans were made relatively late in the process, but [the remodeler] and his team did a fantastic job rolling with the changes.”

“Finally, I want to say that I cannot think of one [of the remodeler’s] employee or one contractor that worked on my house that didn’t do a great job and wasn’t pleasant.  And I was there a lot.  Good character and trust are extremely important to me, and I trusted and liked everyone that I came in contact with.  Frankly, that was a very nice surprise.”

Live Green, Live Smart’s The Sustainable House TM is a participant in Minnesota GreenStar’s Remodeling pilot program and the LEED for Homes Pilot ProjectTM. Live Green, Live Smart has transformed an ordinary post-War rambler in a suburban neighborhood into a Century hour that will be energy efficient, environmentally healthy, respectful of the natural environment, and comfortable for family life as climate and energy resources alter in the coming decades.

Environmentally-Conscious Applications

The green building materials and techniques as applied to the House are less conspicuous than alternative energy sources, but no less important to our Platinum remodel.

• Efficient insulation and an air transfer system ensure that none of the heat or cold generated goes to waste, and that the air inside the home stays clean and breathable.
• Solatubes provide natural sunlight all day long, even in the basement, reducing electricity needs.
• Every lightbulb in the house is an energy-efficient compact fluorescent or LED.
• Low-voltage radiant in-floor heating is an efficient way to reduce furnace needs.
• Greywater is collected from the showers for reuse in the double-flush toilets.
• Windows are triple-glazed and argon-filled to reduce heat transfer.
• Appliances are EnergyStar rated, and an induction stove is used for cooking.
• All electrical energy purchased from the grid is the product of windfarming – no coal-fueled energy will be used in the House.
