Hidden Villa Hostel and Summer Camp Site Plan

Hidden Villa Hostel and Summer Camp

This combination of new and renovated structures harmonizes the educational, community-oriented spirit of Hidden Villa with the site’s agrarian precedent. The new hostel nurtures environmental awareness by demonstrating passive solar design, energy efficiency, and sustainability first hand.

The jurors praised the project’s simple yet elegant cross sections, its respect for the site and the trees, and its architectural integration of the energy efficiency measures. The project is timeless in its use of features such as friendly louvered porches that provide shading and a layering effect and volunteer-constructed rammed earth walls that supply thermal mass. The site plan is like a great solar clock: It reaches out and gathers the sun at the right places during the year.

    Notable Accomplishments

  • Architectural integration of the energy efficiency measures.
