Interlock House

AIA Tour

Circle of architects braving the heat to hear about the Interlock House.  One is admiring our shiny windows.

Hello internet friends,

Sorry it's been a few days since I last posted anything, it's been another busy week.  Anyhow, last night Eric, Dana, Clare and I gave a tour of the house to the Central States AIA Chapter.  It was really hot out so I hope we made it worth their while to come see our project.  They all seemed very interested and asked lots of questions, which I always take as a good sign.  Hopefully they didn't judge our effort and ability by our housekeeping skills.  Speaking of giving tours, keep an eye on the calendar on the left side of the website, it lists upcoming events including tours and open houses.  It's a little sparse right now but it will fill up when the semester starts again.  Take care and good luck avoiding the heat.


Fabulous Footpad Forms

Wood + rebar = concrete form.

Peter is working on a form for new concrete footings. Currently, the house rests on wood footings. There have been a lot of storms in the last couple of months and the wooden footings are starting to warp. The new concrete footpads won't warp due to the weather. We can all rest assured that the house will no longer rise and fall with humidity level.

Radiant Floor Heating

Our heated subflooring is beautiful, some would even say it looks radiant

Happy belated Father's Day to all the dads reading this. I think we've talked about this once or twice on the website but we've never had a good picture of the radiant floor with the tubes installed. Our radiant floor was donated by Warmboard. Warmboard is a structural subfloor that incorporates radiant heating. You can see the grooves routed into the floor. The orage tubing runs from the hot water tank and circulates solar heated water. The greenish layer is actually aluminum, which spreads out the heat and reduces hot spots. Using this system, the Interlock House only uses enough electricity to run two small pumps to heat the entire house. The best part is that it'll feel great to walk around barefoot in the winter!

Getting Crowded

Warehouse contents: more lumber and boxes than you can shake a fist at.

Remember the last photo of the decking? It looked like there was lots of space around it. Well that is no longer the case. As you can see, the warehouse is filling up with lots of stuff. Most of it is framed deck sections and the remaining lumber for creating the decking surface. The boxes right in the middle of the shot contain the NanaWall doors and compoenents. Lots of other donated products can be seen along the left edge. It's getting to be quite the maze in there. It's actually kind of exciting seeing everything coming in to complete the house.
