For over two decades, Marius Ardelean has been a defining figure in the North Texas luxury construction landscape. His career isn’t measured just in years, but in the enduring quality of the homes he creates. With over $100 million worth of custom estates and complex additions successfully delivered, Marius has earned a reputation for technical precision and unwavering transparency.
Why Experience Matters in 2026
In an industry where firms often prioritize volume over value, Marius remains personally invested in the structural and aesthetic success of every project.
25 years of navigating the unique soil conditions, climate demands, and municipal codes of Dallas, Plano, and Frisco.
Specialized in the high-stakes engineering required for vertical additions and large-scale estate transformations.
A track record of delivering high-cap projects on time and to a professional standard that production builders cannot match.
The Simon Joseph Standard
Marius founded Simon Joseph on a simple principle: Architecture first. By integrating advanced 3D visualization into the design phase, he allows homeowners to verify every detail of their project before construction begins.
