We revive the architectural language of historic fireplaces through original designs carved in natural stone.
signature shape
Mantel House has become known for its refined Victorian arches—sculptural profiles inspired by original 19th-century fireplaces and thoughtfully adapted for contemporary homes.
FOUNDER-LED
Every project is guided directly by Molly from the earliest design conversations through stone selection and production. Clients work with the person designing the fireplace, not layers of sales representatives.
HISTORIC PRECEDENT
Every Mantel House profile begins with careful study of 18th- and 19th-century originals. Rather than reproducing them exactly, we refine their proportions to suit today's homes while preserving their architectural integrity.
natural stone
We work exclusively in natural stone- timeless, tactile, and full of nuance. Every block is selected for movement, character, and permanence.
Meet Molly
Founded in 2020 by Molly Acorn, Mantel House began with a passion for exceptional antique marble fireplaces. Sourcing, restoring, and studying original Victorian and French mantels—while working closely with homeowners, designers, and architects—led to the development of an extensive archive of historic fireplaces and revealed a growing demand for mantels that captured the character of an antique while allowing their scale, stone, and details to be tailored to each project.
Every project is personally guided by Molly. Her study of historic fireplaces has cultivated a deep understanding of architectural precedent, an intuitive eye for proportion, and the ability to communicate design ideas visually. Through references, renderings, and collaboration, she helps clients gain clarity, refine ideas, and confidently bring each project to life.
Before founding Mantel House, Molly worked in product development and fragrance for leading suppliers and retailers. Developing products taught her how to translate an idea into a beautifully realized object, while fragrance deepened her understanding of how people experience spaces through feeling, atmosphere, and the senses. Together, these disciplines continue to inform every Mantel House project.
Today, every Mantel House mantel is designed in Washington, D.C. and made to order — tailored in stone, scale, and detail to the space it's built for.
