Some architectural details are meant to be admired. Others are meant to be experienced.

Part of the new addition, this custom brick masonry Roman archway was thoughtfully constructed to feel as though it has always belonged.

Every brick carefully selected to seamlessly match the original masonry, creating a beautiful transition between old and new.

A passageway where craftsmanship, architecture, and experience come together.

Luxury isn’t defined by one statement piece—it’s built into every line, transition & surface.

In the kitchen of this Upper Montclair Historic full renovation home, a coffered ceiling with deep, decorative molded beams draws the eye upward, adding architectural rhythm, dimension & a sense of grandeur. In the dining room, floor-to-ceiling picture-frame molding wraps the walls in rich depth, transforming the bold navy palette into an immersive design experience.

Together, these custom millwork details create a seamless architectural language between rooms—elevating the home through proportion, craftsmanship & intention.

This is the RTH approach to luxury: timeless details, thoughtfully executed.
