About St. Louis Park Interior and Exterior Remodel and Addition
A Young Family and a Unique Home This is one of the most unique homes we have had the pleasure of renovating.
The clients had a few priorities to share with us to define the project scope. Expanding the upper level to provide separate bedrooms and a bathroom for their young boy and girl was number 1.
In no special order they also wanted:
— A fabulous new kitchen and entryway .
— A high performance energy package built into the project.
— An improvement of water mitigation at the homes perimeter.
Back to the unique features of this home. The home is a combination earth/two story home. The back half of the home is built into the earth. The lot is not so much a hill but has a 12 ft. rise from the front to the back. The back half of the main floor of this home has the back yard on top of it!
By now you might be wondering what is holding up the yard over the house. Good question.
The simple answer is that the ceiling consists of concrete panels that are insulated and waterproofed under the soil and grass. The kind of panels you might see in commercial construction. This makes for a challenge to have a functioning mechanical system as it’s a no-no to drill through the planks.
The planks run from the back of the house all the way to the front. The whole ceiling in the main level is cement!
To avoid drilling through the concrete planks and to add the necessary space needed for the bedrooms, we extended the upper level three feet. This allowed for a “mechanical chase”. Large rebar re-enforced footings and new framing can be seen in these photos of the progress.
This home was designed by an architect who works at SALA and who also is the president for MN GreenStar. He insisted on a high performance package along with proper duct sealing. The system would be tested by a blower door. The thermal envelope features staggered stud framing, closed cell, and batt insulation at the walls. The ceiling featured closed cell insulation along with blown cellulose to achieve an R-60 insulation value.
The upper level required around 15,000 BTU’s to supply warmth. This was accomplished with what is known as a “mini-split” system. It uses an air source heat pump to warm and cool the space. Unique to this system is that it is ducted and also features electrical heating elements in the ductwork for back-up heat. They work the same as baseboard heat but have the advantage of being in ductwork which of course allows the heat to be circulated.
The following photographs show the progression from the demolition upstairs to the framing with the extension to the front and then to the finished children’s bedrooms. Visit this project’s Portfolio Page to see additional images of the finished product.
Water mitigation was challenging. Most of the home is underground and the existing waterproofing worked well but could be improved with drain tile. We added a tile to the side of the garage along with drainage boards and waterproofing above the tile to the finished landscaping. We also “cut” the back yard to improve water flow away from the building. We will track the water mitigation over time.
This was a great project with great homeowners. The finishes in the home are warm, beautiful, and friendly.
