A New Model for Habitat for Humanity a study of assembly by means of framework
An undergraduate thesis study by David Parke Pollard May, 2003 Advisors: Steven Thompson Hunter Pittman Jay Stoeckel
introduction In the New River Valley, Habitat for Humanity exists with the mission to provide simple, decent housing to families in need. This mission is accomplished by volunteers acting as carpenters with little to no construction experience. To address this issue, designs and construction methods are chosen in order to cover any marks of trade. The intricate framing systems of the building are covered by vinyl siding Sadly, all trademarks are erased from the exposure of the house.
This project proposes a different approach to the design and construction methods of a Habitat for Humanity house.
A new framing system is developed to expose the implicit lines of the building. The same off-the-shelf products used in all other Habitat houses are rearranged and assembled in a comprehensive system that reveals the trademarks of the volunteers. the interior and exterior spaces of the house. As a result the placement of every part reveals its relationship to the whole. Suddenly the relationship of a single nail to the whole of the building is exposed. To address the issue of building construction, this proposal includes the use of repetitious systems of assembly. The systems are explained through detailed instruction sheets handed out the volunteers by the site supervisor. The result of this proposal is a building with a high level of craft revealed in its details. The mark of the volunteers and the designer are
project The building is a small two-bedroom house located in Bluff City, just outside of the town of Pearisburg, in southwestern Virginia. The construction materials are limited to offthe-shelf products such as concrete block, dimensional lumber, sheet metal, concrete, and corrugated steel. The form of the building evolves as different construction systems frame each other. Block walls frame post and beam assemblies, which in turn frame wall systems. Window and door openings begin to be framed by these interesecting systems. The plan is nine-square, with all the servant spaces occurring in the western third. The entrance and exit happens in the third between the served and servant spaces. The southwestern quadrant of the building is the front entrance. This space is left unenclosed but covered. Here the vertical circulation occurs through an intricate framing system. Southern sunlight enters the house through this framework further exposing the frame through shadow.

assembly To maintain a high level of craft in the builidng, it is critical for the volunteers to have an understanding of the whole of the assembly of parts. The proposal is for a series of assembly sheets to be developed and given to the volunteers. Each sheet is broken into a structure that demonstates the relationship of each part to the whole building. Each major phase has a master sheet that relates it to the whole building. Each master sheet is then broken down into smaller sheets revealing the assembly of each piece.
