LIT Design Co. is a boutique interior design firm specializing in comprehensive home design, from new construction and remodels to furnishings. Our company was founded on the principle that design should be creative, beautiful, comfortable, and dynamic, transforming spaces into lifestyles rather than just homes.
With over a decade of experience in residential, commercial, and lighting design, our projects achieve both aesthetic and economic success for our clients. We believe that creating beautiful spaces with purpose requires two essential elements: passion and time. Our approach is meticulous, emphasizing continuity, management, and achieving successful project outcomes.
We are deeply committed to every aspect of home design, meticulously managing specifications and meticulously drawing interior design details to ensure the highest quality in new construction or luxury remodels.
Let’s create something meaningful together.
Originally from El Paso, Texas, Mariana Loya studied Interior Design at the University of the Incarnate Word in San Antonio, where her love for thoughtful, intentional spaces took shape. She began her career in lighting design, learning firsthand how light can transform mood, comfort, and architecture. From there, she expanded into residential and commercial interiors with a collaborative, detail-driven approach. Today, she leads LIT Design, a boutique studio specializing in luxury remodels, new construction, and fine furnishings. When she’s not designing, Mariana is a proud mom of two boys and can often be found on the pickleball court.
