Timeless architecture, exceptional construction and extraordinary pride of ownership define 113 Richelieu Drive in Cary's highly coveted Regency Park Estates. Thoughtfully designed by Carter Skinner and set on just over an acre of land, this all-brick estate offers nearly 10,000 square feet of thoughtfully designed living space that feels substantial without feeling overwhelming. Every room has a purpose and despite its remarkable scale, the home lives with a warmth and comfort that's increasingly difficult to find in a property this size.   Built with a level of structural integrity rarely found today and anchored by steel beams, the architecture is classic, substantial and designed to stand the test of time. Throughout the home, thoughtful details reveal the exceptional attention that goes into its design. From the gracefully rounded, fluted corners that adorn the walls to the refined millwork and finishes, each element gives the space a sense of permanence and craftsmanship. Add to this the exceptional pride of ownership shown by original owners to create one increasingly rare property where virtually every detail reflects meticulous care.   The primary floor is designed for everyday living including a kitchen thoughtfully refreshed with a full suite of recently replaced Thermador appliances, newly refinished cherry hardwood floors with a sophisticated matte sheen and a private primary suite complete with a sitting area, large walk-in closet, and pristine primary bathroom. Each room on the back of the home benefits from a dedicated entrance to a breathtaking veranda porch running the full expanse of the exterior and overlooking resort-like saltwater pool. Upstairs, four generously sized bedrooms each enjoy an attached full bathroom and walk-in closet, creating comfortable accommodations for family and guests alike. An additional fifth bedroom offers exceptional versatility, easily adapting to a bonus room or flex space. A full theatre provides a dedicated entertainment experience, while easily accessible walk-in storage offers the kind of practical functionality that makes a home of this size easy to live in. The lower level is an amenity-rich retreat all its own, featuring a full guest suite, gym, entertaining space, bar setup, unfinished storage, and an impressive 1,000-bottle wine cellar with a newly replaced cooling unit. Designed with entertaining in mind, this level also features both interior and exterior fireplaces, along with a dedicated pool bathroom complete with a steam shower. Mature trees and established landscaping create a private, serene backdrop, while a black aluminum fence frames the property beautifully. A five-inch thick, circular driveway creates a gracious arrival and adds to the home's timeless estate presence.  Set within Regency Estates, the home enjoys the privacy and mature landscaping of one of Cary's established luxury neighborhoods while remaining exceptionally connected to the rest of the Triangle. Convenient access to major highways, WakeMed Cary Hospital and other medical facilities, shopping, dining, parks, and Raleigh's broader business and cultural centers makes the location as practical as it is prestigious.  Perhaps most compelling is what you don't have to do. All five HVAC systems have been replaced along with the roof and transferrable 50 year warranty, and regularly serviced and 2024 installed whole-home generator. Major systems and finishes have been continually maintained and updated, offering the appeal of a timeless custom home with much of the confidence and ease buyers associate with newer construction.  113 Richelieu Drive is for the buyer who values space without excess, timeless architecture over passing trends, and craftsmanship that speaks for itself. A remarkably solid home, meticulously maintained, and built with a level of quality that is increasingly difficult to replicate - opportunities like this rarely become available in the Triangle.
