LIVING HERE
Living at One Watermark
One Watermark is a boutique waterfront building of just 48 residences, designed for buyers who want generous space, privacy, and full-service living on the Intracoastal. Recent listings describe private elevator entries, wide terraces, and views across the water to Palm Beach and the Atlantic Ocean.
Residences in recent listings range from about 4,000 to more than 5,600 square feet of interior space, most with three or four bedrooms, plus private terraces of roughly 700 to 800 square feet. Interiors vary from original finishes to extensively renovated, custom homes.
With only 48 residences and few listings at a time, floor level, exposure, renovation, terrace space, and parking can make two homes of similar size live, and price, very differently. At this level of the market, the details of each residence matter as much as the address.

What Influences Condo Values at One Watermark?
Two residences at One Watermark can sell for very different prices. Value typically depends on a combination of factors:
- Floor level. Higher floors open up wider water and ocean views.
- Exposure. Eastern exposures face the Intracoastal, Palm Beach, and the ocean, while western exposures look over the city and toward sunsets.
- Size and layout. Three- and four-bedroom plans vary in size and in how they live.
- Renovation and finishes. Custom, fully renovated residences can stand apart from homes with original finishes.
- Terrace space. The size and orientation of outdoor living areas.
- Parking and storage. The number of garage spaces and storage that convey.
- Marina access. Slip availability can matter to buyers who boat.
- Limited inventory. With only 48 residences, a single listing can shape the market.
- Luxury market conditions. Demand from full-time and seasonal buyers at the top of the market.
Why Price per Square Foot Is Only a Starting Point
Price per square foot is a useful benchmark, but on its own it can mislead. A fully renovated residence on a high floor with direct water views may command a higher price per square foot than a larger residence that needs updating, even if the larger home sells for more overall. Terrace size, parking, and finishes can widen the gap further. An accurate valuation compares the most similar recent sales, adjusts for these differences, and weighs what buyers can choose from right now.
