$5 Million ‘Devlin Estate’ Offers a Rare Chance to Finish One of Maryland’s Most Ambitious Private Mansions

Spanning 38 private acres in Howard County, the partially completed 32,000-square-foot Devlin Estate presents a once-in-a-generation opportunity to finish an architectural masterpiece while bypassing years of planning, permitting, and construction.

Most luxury homes arrive on the market fully finished.

The Devlin Estate offers something far rarer—the opportunity to shape one of the largest and most ambitious private residences ever envisioned in Maryland.

Listed for $5 million, the estate at 15125 Devlin Drive occupies 38.25 private acres in the rolling countryside of Glenelg, Maryland. Already framed, enclosed, and substantially advanced through construction, the nearly 32,000-square-foot residence provides future owners with the extraordinary chance to complete a true legacy property while avoiding what agents estimate would otherwise require approximately five years of planning, approvals, and development.

Rather than beginning with raw land, buyers inherit an exceptional architectural foundation ready to become one of the Mid-Atlantic’s most remarkable private estates.

“This is an opportunity that almost never comes to market,” said Hazel Shakur of Redfin Corp. “The vision, scale, approvals, and infrastructure are already in place. The next owner has the unique ability to personalize an estate that would take years to recreate from the ground up.”

Building a Legacy Instead of Starting From Scratch

In today’s luxury market, time has become one of the most valuable assets.

Large custom estates often require years of architectural planning, engineering, environmental studies, permitting, and construction before owners can move in.

The Devlin Estate dramatically shortens that timeline.

With permits, approvals, structural work, and the building envelope already completed, much of the most difficult and time-consuming development process has already been accomplished.

Instead of waiting years before construction even begins, buyers can immediately focus on completing interiors, finishes, technology systems, landscaping, and personalized design elements.

“Opportunities like this simply don’t exist very often,” Shakur explained. “You’re not purchasing unfinished construction—you’re purchasing years of completed work and the ability to bring your own vision to an extraordinary architectural canvas.”

Architecture Conceived on a Monumental Scale

Even in its current state, the home’s architectural ambition is immediately evident.

Towering two-story volumes, expansive walls of glass, and dramatic open spaces establish a residence designed for both everyday luxury and grand-scale entertaining.

At the center of the home, a spectacular floating spiral staircase rises through all three levels, serving as both a functional circulation element and an architectural sculpture.

Large windows frame panoramic countryside views across the surrounding acreage, allowing the landscape to become an integral part of the home’s design.

Rather than emphasizing ornamentation, the architecture relies upon scale, proportion, and light to create its dramatic visual impact.

Designed for Modern Estate Living

The floor plan was envisioned around flexibility as much as luxury.

On the main level, expansive entertaining spaces are complemented by dual kitchens—one designed for everyday family living and another intended to support professional catering during larger events.

A stately library provides a quieter retreat for executive work, private meetings, or reading, while generous gathering spaces allow the residence to comfortably host everything from intimate dinners to large charitable galas.

Throughout the home, circulation between rooms has been carefully planned to support both formal entertaining and practical family living.

A Primary Suite Unlike Anything Else

Perhaps the home’s most extraordinary private space is its remarkable owner’s suite.

Occupying two stories, the suite was designed as a self-contained sanctuary featuring separate spa-inspired bathrooms, expansive dressing rooms, and one particularly memorable feature—a dramatic two-story wardrobe gallery complete with a dedicated designer shoe showroom.

The concept pushes residential luxury beyond traditional expectations, transforming storage into a theatrical architectural experience.

Eight additional bedrooms provide generous accommodations for family members and overnight guests, creating exceptional flexibility for multigenerational living.

“The primary suite alone illustrates the ambition behind this project,” Shakur noted. “It was envisioned on a scale rarely seen in private residential design.”

Entertainment Without Limits

The lower level continues the home’s emphasis on lifestyle.

Plans include a private bowling alley, dedicated home theater, and numerous flexible spaces capable of becoming a wellness center, wine gallery, art studio, additional guest suites, or virtually any combination a future owner desires.

This flexibility represents one of the property’s greatest long-term advantages.

Thirty-Eight Acres of Privacy Near Washington and Baltimore

While many luxury estates emphasize location alone, The Devlin Estate combines exceptional privacy with remarkable accessibility.

Surrounded by 38.25 acres of rolling countryside, the property offers a peaceful rural environment while remaining conveniently connected to both the Baltimore–Washington corridor via Interstate 70 and Interstate 95.

Major employers including Johns Hopkins University and the National Security Agency remain within practical commuting distance, while upscale shopping and dining in nearby Columbia further enhance everyday convenience.

Nature lovers also benefit from proximity to Patapsco Valley State Park, providing miles of trails, rivers, and protected woodland.

Built With the Future in Mind

Beyond its scale, the estate incorporates forward-looking infrastructure designed to support long-term ownership.

A geothermal energy system forms the backbone of the home’s high-efficiency mechanical design, while updated Howard County regulations allowing Accessory Dwelling Units (ADUs) provide additional flexibility for guest accommodations, multigenerational living, or staff housing, subject to county approval.

Because so much of the technical groundwork has already been completed, future owners can focus primarily on design rather than engineering.

“This property gives buyers something incredibly valuable—creative freedom without starting from zero,” Shakur said. “It’s an opportunity to complete a landmark residence that reflects their own vision.”

A Singular Opportunity in Maryland Luxury Real Estate

Large undeveloped parcels near the Baltimore-Washington metropolitan area continue to become increasingly scarce, while entitlement timelines grow longer and construction costs remain elevated.

Against that backdrop, The Devlin Estate occupies a unique position within Maryland’s luxury market.

Rather than purchasing a finished home identical to dozens of others, buyers acquire the opportunity to complete a residence that can truly become one of the Mid-Atlantic’s defining private estates.

According to Shakur, the home’s greatest value lies in its potential.

“The next owner won’t simply finish a house—they’ll complete one of Maryland’s most extraordinary legacy estates.”
