What makes EMD different

A husband-and-wife design-build studio

One stop, all things home: architecture, construction, interiors and furnishings: MRCxEMD.

Ellie Mroz Design works alongside Michael Robert Construction — Mike Mroz's residential remodeling and custom home building company — during renovations, additions, remodels and custom home builds, which means construction and interior design expertise arrive at the same table.

It turns a renovation into one conversation instead of four. The result is a more cohesive home, where architectural decisions, construction details, finishes, and interiors have been talking to each other since the beginning.
