I thought we had a pretty clear idea about what we wanted in the house. We also trusted our designer to help guide us in the details. Our priority was to find an optimal balance of energy efficiency, maximizing the view, and the aesthetics of a modern design, while also respecting our budget.
Our aesthetic draws us to simplistic modern vernacular houses. These simple shapes (square or rectangle) also happen to be ideal for energy efficiency – less angles make for less escape points of energy and thermal bridging at corners. Additionally, these shapes allow for easier transfer of air and heat throughout the interior of the home. A peaked roof can be made to orient at the correct angle for solar exposure of a PV system.
That’s all well and good, but we also had this amazing view in front of us:
As if fate had made it so, the views were south and east. If we’d been north facing we would be in a bit of trouble for energy efficiency – in fact, we would probably fail.
When considering energy efficient and passive solar principles, you need thermal mass. The sun hitting a thermal mass like stone, tile or concrete allows it to warm the surface and passively radiate that heat for the remainder of the day. It just so happens that we quite like concrete floors. These can be very beautiful surfaces that you can polish, grind, or stain. Naturally these all add some cost to the finishing of concrete, however the costs are significantly less than adding flooring overtop. We need the concrete for the slab anyways, so why not use it for our thermal mass and our finished floor?
The more I read about energy efficient design principles, the more and more pleased I was to find that a lot of our aesthetics were coinciding with optimal energy modelling.
Our basic house idea was for a 1700-2000 sq.ft bungalow or 1.5 storey with three bedrooms (although we are DINKs now [dual income no kids], we will likely have some rug rats (concrete rats?) running around at some point) and two bathrooms. Also, we wanted a living room and separate media/rec room. Because we will be canning and storing a lot of our own food a large pantry was also necessary. We want to have a lot of connection to the outdoors, not just through the windows, but also a few exit points to access a deck space and various parts of the yard.
As I’ve previously written, we’d spent quite a bit of time going through Pinterest and numerous design magazines choosing our inspiration photos. As part of our early design process, we also went through and measured the room sizes we liked in our house and those of some friends and family whose room sizes we thought were nice. Still the details of how it functioned needed to be put together. This is where the designer is key.
Crystal Bueckert, our designer, is great. At our first official design meeting she basically listened to us and did the first design exactly as we’d asked. We waited with excited anticipation for the first draft to come back. About two weeks later she sent it to us. Not only did she send us a floor plans but also a 3-D model with a virtual walk-through on our laptop and iPhone. We were so excited to see what it would look like. We opened it up and… we totally hated it!
She had done exactly what we had asked but we absolutely didn’t like it. It was not what we had envisioned at all. Ok, I’m being a bit hard on it. There were a couple things we liked and there was some things that had potential, but overall it was not good. At all.
The next design we revised a number of our thoughts and really tried to think about how we wanted the house to flow. We abandoned the 1/2 storey idea and went to a bungalow. We also changed the position of the living room and kitchen, which made a very significant change to the layout of the entire house… Although we wanted a relatively ‘open concept’ house (from both an energy efficiency and style point of view), we did not want it overly open and in the first design it was just too open.
The second design was a lot closer to what we were going for. Except for one big thing: we recognized that the kitchen/living room/dining room placement was actually a lot better in the first design, although the rest of the house worked WAY better than the first go around. Still we were getting closer.
Sadly, the third version was a bit of a mess, we had considered moving the mechanical room to the attic to free up floor space as we really wanted to keep it under 2000 sq.ft total. That quickly came to a halt when I had a nightmare about the water heater breaking, spewing water through the ceiling and down the walls – destroying everything I cared about. I told Crystal that we had to fit the mechanical room into the main floor. We also wanted (Darcie said ‘needed’) to switch the kitchen and living room again – a massive design change again.
I’m confident the fourth design is going to be very close to the final product. The layout flows beautifully and to solve the space problems we actually went smaller. Shrinking the size from 2300 sq.ft in design #2 to 2050 sq.ft. There are a few minor changes to make, but I feel like we are about 90% completed.
Now that we had the layout near completion we needed to figure out the big questions of wall systems and mechanical heating/cooling.
