A New Custom Waterfront Estate Rising in Admirals Cove

Some opportunities in Admirals Cove are worth watching long before the finishing touches are complete. 404 Mariner Drive is one of them.
In Rob Thomson’s latest video, viewers get an early look at this new custom coastal contemporary waterfront estate through detailed renderings that reveal exactly what is coming: a residence of dramatic scale, refined design, and resort-style outdoor living on one of the community’s most unique oversized homesites, complete with direct Intracoastal access and no fixed bridges.
Priced at $17,500,000, 404 Mariner Drive offers 5 bedrooms, 7 full bathrooms, 3 half bathrooms, more than 8,000 square feet of air-conditioned living space, and over 10,300 square feet of total covered space, including an attached private guest residence.
Here is your first look at what is taking shape.
An Exceptionally Wide Estate Lot With Direct Intracoastal Access
The setting is what makes this opportunity so rare. 404 Mariner Drive is positioned on an exceptionally wide estate lot, one of the most unique oversized homesites in Admirals Cove. That scale gives the residence commanding curb appeal and room for the kind of outdoor amenities that simply cannot fit on a standard waterfront parcel.
For boaters, the location delivers one of the most important features in Jupiter real estate: direct Intracoastal access with no fixed bridges. It is the kind of waterfront positioning that serious yachtsmen seek out, in a community already celebrated for its boating lifestyle.
A Custom Coastal Contemporary Design
Designed with both elegance and functionality in mind, the home makes a striking first impression. An expansive motor court leads to a five-car garage, ideal for automotive enthusiasts and collectors, along with a dedicated golf cart garage for everyday club living.
A grand double-height entrance sets the tone for the architecture inside, where a thoughtfully curated floor plan balances luxurious everyday living with sophisticated entertaining. A state-of-the-art culinary kitchen anchors the main living areas, complete with an expansive scullery pantry, an elegant wet bar, and a glass wine room. A stunning custom glass office adds another layer of sophistication to the home’s modern design.
A Private Primary Retreat and a Waterfront VIP Suite
The primary suite and a separate guest suite are both located on the first floor. The primary serves as a true private retreat, featuring his and her walk-in closets, separate water closets, and an outdoor shower designed to create a spa-like experience at home.
Upstairs, three additional bedrooms include a waterfront VIP suite, and each enjoys a private balcony with views of both the water and the resort-style pool below. Every bedroom in the home is en-suite, giving family and guests comfort and privacy throughout.
An Attached Private Guest Residence
One of the most distinctive features of 404 Mariner Drive is its attached private guest residence. Whether used for extended family, VIP guests, or live-in staff accommodations, it adds an exceptional level of luxury, privacy, and versatility while enhancing the estate’s overall grandeur and functionality.
Accommodations at this level seldom come together in a single Admirals Cove offering, and they speak to how thoroughly this home was designed around real luxury living.
Resort-Style Outdoor Living on a Grand Scale
The renderings of the backyard tell the story of what this oversized lot makes possible. An oversized covered lanai creates the ultimate outdoor entertaining environment, with a fireplace, full bar, expansive dining area, and built-in barbecue space overlooking the water.
Beyond the lanai, an enormous resort oasis-style pool features an infinity-edge spa, floating daybeds, and a relaxing sun shelf with a water feature. A waterfront fire pit gathering area and a private putting green complete the outdoor amenities, delivering a South Florida lifestyle that rivals the finest resorts.
The Admirals Cove Lifestyle
Admirals Cove continues to set the standard for luxury club living in South Florida. Residents enjoy 45 holes of championship golf, a full-service marina with direct ocean access, multiple dining venues, an expansive fitness and wellness center, tennis and pickleball facilities, and a private boutique hotel for members and guests.
For those seeking waterfront living, boating, golf, and a true private club environment in one address, Admirals Cove remains one of Jupiter’s most sought-after communities.
Why Early Interest Matters at 404 Mariner Drive
Custom estates of this caliber, on lots of this scale, with direct Intracoastal access and no fixed bridges, rarely reach completion without serious interest. Buyers who wait until the home is finished may find the opportunity has already passed.
404 Mariner Drive brings together a combination that is difficult to replicate in Admirals Cove: a new custom coastal contemporary design, an exceptionally wide estate lot, an attached private guest residence, a five-car garage, and resort-style outdoor amenities, all on deep water.
