Best Footing Forward

Collage of slab to core connections

Welcome back to the CLT Core House team blog! It has been a busy month filled with details and deliberation. As the title suggests, we have been focused on our footing design, particularly on the connection of our heavy and bulky CLT core to our concrete slab. We wish it were as simple as just “screwin’ er’ down.” However, because the slab will be on grade at ground level, we’ve found it difficult to design the right detail. We have worked through many kinds of solutions, all of which we eventually dropped for either being too complicated or too messy.

While working through footing details, we have identified the need for our core to be a six-sided box that arrives on-site wrapped like a present with a bow: something that you only unwrap once you are finished with the dirty business of finishing a house. Also, we know we want our concrete slab to be finished in one pour to avoid the orchestration of getting a concrete truck and team on site multiple times.

Our latest strategy—single-pour slab and a completed box—may not seem like much, but it eliminates most of our previous hurdles. As we both design the core and develop the process of moving and placing it, we are focusing on making sure others can easily replicate our work in the majority of rural contexts. The footing, our most recent detail, is hitting most if not all of our criteria and we continue to examine and refine it. What’s funny is that the final connection is only screws, so we may just be screwin’ er’ down after all.

In Other News,

We have been steadily working in various other areas of the project. We are drawing elevation options, both interior and exterior and considering where our porches should be and what they look like. We are also asking ourselves what the human comfort scheme is, which is the heating and cooling of the house, and what passive strategies we could employ.

We have also been in the business of testing the spatial aspects of the cores and taking field trips to Rural Studio projects and places.

This point in the project is exciting. Hopefully, in the next blog, you will see a mock-up and some details that are finally nailed down, pun intended.
