Custom Homes & High-End Additions in Plano, TX

Legacy Excellence Meets Modern Innovation.

Plano is home to some of North Texas’s most iconic residential architecture. However, many of these “legacy estates” require structural evolution to meet today’s standards for open-concept living and wellness-centric design.

With 25 years of experience and over $100 million in project value delivered, Marius Ardelean specializes in the complex engineering required to modernize these properties. We don’t just renovate; we structurally adapt your home for the next generation.
