The Files subseries consists of standard forms of agreement, change orders, invoices for architectural service, applications and certificates of payment, specifications, photographs, notes, correspondence, drawings and sketches, purchase orders, job reports, schedules, and other material created by Pettersen (and, to a certain extent, her associates) in the course of work on various residential and commercial projects. Projects primarily include the design and construction of new residences, and additions and alterations to existing residences. Most projects are located in New Jersey although there are also projects in New York, Massachusetts, Vermont, Connecticut, Maine, Michigan, Colorado, Virginia, North Carolina, South Carolina, Georgia, Tennessee, and Florida.

Pettersen classified some of her files as "Dead Files." This classification has been retained and is indicated in the Project Index with an italicized box number. The "Dead Files" include boxes 40-47.

The Specifications subseries consist primarily of master copies, but also some draft and office copies, of specifications for various projects. Copies of specifications can also be found in the Files subseries; these copies were maintained distinct from the project files and therefore seem to warrant arrangement as a separate subseries.

The Drawings subseries includes architectural plans and sketches on a variety of formats including trace paper, diazo prints, blueprints, and CAD drawings.

Accession came from the estate of Emily Schultz, friend of Eleanore Pettersen.
