About Us

Four over One Design, LLC is a woman-owned preservation design and consulting business, founded in 2009. 4/1 focuses on the older houses around the Triangle area, and relishes taking a building that has been altered over time and putting it back to rights while bringing it up to modern standards at the same time.

Owner, Four Over One Design

Originally from Chapel Hill, I completed an undergraduate degree in Studio Art from Smith College.  While I knew nothing about the field of preservation then, I loved the old buildings on campus and the sense of place they conveyed.  A few years out of college, I attended graduate school at UNC-Greensboro and received a MS in Interior Architecture with a concentration in Historic Preservation – setting myself at the intersection of preservation and design.

I founded 4/1 after completing three years as the Director of Design and Preservation with Trinity Design/Build, where I worked directly with the contractors to complete 17 renovations, additions, and remodels.  Now, I particularly appreciate being able to customize my services to what a client really needs for a given project.  After all, no two houses (and no two families!) are the same.

My two sons, one skinny dog, and I live in a midcentury ranch just north of town.  We love our old neighborhoods, local food and drink, and Durham in all ways.
