In this series, Sebastian Mariscal designs a home in Venice, California, that brings the outside in. We track the project from start to finish with future resident Michael Sylvester. Part 6, September 2011: Preparing the Footings.

Our house will have concrete slab floors and these are produced in a two step process that involves pouring the trench footings and then pouring the finished slabs. In the slideshow that follws, we take a look at the process.

The outlines of footings are marked on the ground. This is the first 1:1 scale layout of the home, which makes for an interesting walk around the site

The orange flags mark tree roots that cut across the footings. Major roots were carefully preserved during the trench digging. However, a few roots were accidentally cut and fighting to protect the trees is an ongoing battle.
