17. Section Diagram

A house is typically not designed to support the load of a second story, so the project was envisioned as a bridge spanning from a new dining room at the rear to a false front facade, thus floating effortlessly above the existing house.

Description

LOC was presented with a modest two bedroom bungalow nestled in the foothills of the San Gabriel Mountains. Constrained by a small backyard and a mature protected oak tree in the front, the only possibility for adding two additional bedrooms was to create a second story, one that was constrained by but ultimately become a paean to the tree.

Questions and Answers

How is the project unique?

The tree.

What was the brief?

The client, a material engineer at the Jet Propulsion Laboratory, gave LOC a straightforward project brief- two add two bedrooms and two bath to a small two bedroom bungalow in La Crescenta, CA

Key products used:

Amteco Wood Stain
Milgard Windows

Who are the clients and what's interesting about them?

The client is a material engineer at the Jet Propulsion Laboratory. He took a particular interest in the cedar cladding of the project, as we all wanted to maintain a natural look and minimize maintenance. We ultimately settled on an Amteco Wood Stain

What were the solutions?

Adding a second story to an existing house is problematic, as the existing structure is not designed to support a second floor. We addressed this by rebuilding a dining room at the rear and adding a false wall at the front facade, allowing the new second story to span over the existing house, like a bridge.

What were the key challenges?

The site was quite small, with a very small backyard, and a mature protected oak tree in the front, forcing us to add vertically, and two build extremely closely to the tree which required additional permitting due to its protected status
