The analysis covers 178 closed single-family sales at $3M+ with a Year Built of 2020 or later, sourced from BeachesMLS via Spark API. For each sale, we track living area, lot size, $/SF, days on market, list-to-sold ratio, city, community, waterfront status, and ocean/ICW classification. The volume market ($1M-$3M master-planned communities) and condo pipeline (Alina Residences, 151 sales) are addressed as context but are not the focus of this report.
The Luxury Pipeline
The 178 luxury SFR sales split into three tiers that behave as distinct markets. At $3M-$5M (78 sales), the product is primarily non-waterfront rebuilds in established communities and select east-of-95 infill. Ocean/ICW access is 35%. At $5M-$10M (63 sales), waterfront share rises to 43%, and the product shifts toward Intracoastal and river-front custom homes. At $10M+ (37 sales, $804 million in volume), 62% have ocean or Intracoastal access, and the median living area is 8,110 square feet. The waterfront concentration increases with price because the highest-value lots, the ones worth tearing down and rebuilding, are disproportionately on the water.
The chart shows volume concentrated in the $3M-$5M tier (78 sales), but the dollar weight is at the top: the 37 sales at $10M+ generated $804 million, more than double the 78 sales at $3M-$5M ($305 million). The luxury new construction market is top-heavy in the same way the broader PBC luxury market is. The $10M+ tier accounts for 21% of sales but 53% of volume.
Where They Are Building
The luxury spec and custom market concentrates in four corridors, each with a distinct buyer profile and product type.
Jupiter (17 sales at $5M+, avg $15.7M, $1,863/SF):
The highest average price of any city. Admirals Cove produced 10 of these 17 sales at an average $14.8M and $2,282/SF. The balance is Intracoastal and Loxahatchee River frontage outside gated communities. 76% waterfront. The defining feature of Jupiter waterfront at this level is deep-water dockage on wide canals and river frontage, typically accommodating vessels in the 60-to-100-foot range. The buyer profile skews toward active boaters building 6,000-10,000 SF homes with 80+ feet of water frontage.
Delray Beach (17 sales at $5M+, avg $15.0M, $1,183/SF):
Includes Stone Creek Ranch (3 sales, avg $36.4M, $2,320/SF), the county's highest-value new construction enclave, alongside east Delray oceanfront and Intracoastal spec homes. 41% waterfront. The non-waterfront sales at this tier are east-of-95 tear-downs on oversized lots in neighborhoods like Lake Ida and Tropic Isle, where the land position carries the value.
Boca Raton (25 sales at $5M+, avg $8.5M, $1,220/SF):
A mix of Royal Palm Yacht and Country Club rebuilds, East Boca infill, and select gated community spec. Lower average price than Jupiter or Delray because the $5M+ product mix includes more non-waterfront (56%). The typical Boca spec home at this tier is a 5,000-7,000 SF rebuild on a golf or lake lot within an established club community.
North Palm Beach (8 sales at $5M+, avg $13.7M, $1,201/SF):
Lost Tree Village and surrounding waterfront. 75% waterfront. Small volume but high average price. The new product here is replacing 1980s-90s ranch-style homes on some of the most private waterfront lots in the northern corridor.
West Palm Beach (12 sales at $5M+) and Palm Beach (6 sales) round out the top six cities. West Palm Beach activity is primarily Intracoastal-facing spec in the Southland Park, Northwood, and El Cid corridors, where developers are replacing 1950s-60s block homes on 75-to-100-foot waterfront lots. Palm Beach Island's 6 sales reflect the scarcity of teardown-eligible lots on the barrier island rather than a lack of demand. The remaining 15 of the 100 $5M+ sales are distributed across smaller municipalities.

What Gets Built
At $5M+, the median post-2020 home is 5,960 square feet on a 16,000-square-foot lot. At $10M+, 8,110 square feet. The construction is CBS to the current Florida Building Code, with higher wind-load ratings than pre-2020 code. Impact-rated windows and doors are standard. The finishes reflect current buyer expectations: European appliance packages, wide-plank flooring, floor-to-ceiling glass, covered outdoor living with summer kitchens, and pool-spa configurations designed as extensions of the interior.
The functional gap between a 2025 spec home and a 2005 resale on the same street is not cosmetic. It is structural: current wind code, current electrical panel sizing (for EV charging and battery backup), current plumbing standards, and an open floor plan versus the segmented layouts typical of pre-2010 construction. That gap is what the $3M+ buyer is paying for when they choose new over resale.
At $10M+, post-2020 homes are larger, not smaller.
Post-2020 $10M+: 37 sales. Median 8,110 SF. Median $/SF $2,198.
Pre-2020 $10M+: 90 sales. Median 6,924 SF. Median $/SF $2,462.
The post-2020 buyer at $10M+ is building more house on premium lots, which mechanically lowers the $/SF. A buyer who acquires a waterfront lot in Admirals Cove, Lost Tree, or east Delray and builds a home that maximizes the buildable envelope will show a lower $/SF than a smaller, older home on a comparable lot, even though the total cost is higher. The $/SF is lower because the numerator (land + structure) grew less than the denominator (interior square footage). The land cost is embedded in the total price, not separated in the MLS data.
Pricing Relative to Resale
Blended "new construction" statistics for PBC show a 36% $/SF premium over resale in 2025. That figure is driven almost entirely by luxury condo deliveries (Alina Residences at $979-$1,532/SF) pulling up the average. When single-family is isolated, the picture is different.
At $3M-$5M, post-2020 SFR trades at parity with pre-2020 ($888 vs. $886/SF). At $5M-$10M, post-2020 trades at a 14% discount ($1,155 vs. $1,346). At $10M+, an 11% discount ($2,198 vs. $2,462). The explanation is geographic: the highest-$/SF resale properties are on Palm Beach Island, Manalapan, and Gulf Stream, where post-2020 new construction is rare. New spec homes are concentrated in Jupiter and east Delray, where absolute $/SF is lower because the land, while premium, does not carry the same per-foot cost as a barrier island. A new $12 million home in Jupiter at $1,800/SF and a pre-2020 $12 million resale on Palm Beach Island at $3,000/SF are not comparable transactions.
When geography is held constant, the apparent county-level discount disappears. Post-2020 SFR in Jupiter trades at $/SF comparable to pre-2020 resale in Jupiter. The same is true in Boca Raton and Delray Beach. The discount in the blended data is an artifact of where the pipeline is concentrated, not what the product is worth. A secondary effect: in communities where post-2020 spec homes are selling alongside pre-2020 resale, the new product is setting comps that reflect current construction quality, and buyers are using those comps in negotiation on the older inventory.
The Volume Market
Separate from the luxury spec and rebuild market is the master-planned community pipeline that has added significant new inventory to the $1M-$3M band. In 2025, 407 single-family homes built since 2020 sold between $1M and $3M, concentrated in communities like Avenir and Artistry in Palm Beach Gardens, Lotus and Boca Bridges in Boca Raton, and Valencia Grand in Boynton Beach. These developments sit west of I-95, on land that was agricultural or undeveloped five years ago, at $389-$654/SF.
This product serves a different buyer: families and professionals who want new finishes, community amenities, and move-in condition. It is not competing with the waterfront resale market. It is competing with 2005-2015 resale in established gated communities at comparable or higher $/SF. A buyer choosing between a 15-year-old home at $650/SF in Woodfield or Mirasol and a new home at $600/SF in Artistry is making a location-versus-condition decision. The master-planned pipeline is winning a meaningful share of those decisions.
The condo pipeline is a separate phenomenon, dominated in 2025 by Alina Residences in Boca Raton (151 sales, $513 million, Phase I at $979/SF and Phase II at $1,532/SF). No other condo project approaches Alina's volume. The 2025 condo new-construction figures are a one-project story that will not repeat until the next major development delivers.
Bottom Line
The luxury new construction pipeline in PBC is a replacement cycle on established land. At $3M+, 178 post-2020 single-family homes traded in 2025, concentrated where lot values are highest and existing structures are oldest. The $10M+ tier accounts for 21% of these sales and 53% of the dollar volume. When geography is held constant, post-2020 SFR trades at $/SF comparable to pre-2020 resale. The buyer is not paying a premium for new. They are building more house on land that already commands the premium.
For buyers at $5M+: The spec market in Jupiter, Delray Beach, and North Palm Beach delivers current-code waterfront at $/SF that is at or below comparable resale in the same location. The value is in the land position, and the structure is new.
For buyers evaluating a tear-down: 37 post-2020 homes sold at $10M+ in 2025. This is an active, liquid market with an established comparable set. The data supports underwriting a rebuild on a premium lot as a known transaction type, not a speculative one.
For sellers of pre-2020 homes in established communities: Post-2020 spec homes on comparable lots are now setting comps. A 2005-vintage home competing against a 2024 spec build on the same street needs to price the structural gap or close it through renovation. The buyer has a choice that did not exist five years ago.
Real estate data covers all closed single-family residential sales at $3,000,000 and above in Palm Beach County, sourced from BeachesMLS via Spark API. The 2025 full-year dataset is the primary analysis period.
"Post-2020 construction" is defined as properties with a Year Built value of 2020 or later. This captures developer-delivered spec homes, custom builds completed by the owner, and recently completed properties that have been resold. A property built in 2021 and resold in 2025 is included because its construction quality, building code compliance, and physical condition are functionally current. This definition is broader than the traditional "new construction" label (first sale from developer).
Ocean/ICW classification was derived by text parsing of Public Remarks, Features, Subdivision, and Development Name fields for keywords including "ocean," "oceanfront," "atlantic," "beachfront," "intracoastal," "ICW," and "Loxahatchee River." Properties flagged as waterfront in the MLS but mentioning only lake, canal, or pond were excluded from the ocean/ICW count. This classification is approximate.
The $/SF comparison between post-2020 and pre-2020 is not a like-for-like comparison. Post-2020 SFR is concentrated in locations (Jupiter, Delray Beach) with lower absolute $/SF ceilings than the locations that dominate pre-2020 resale (Palm Beach Island, Manalapan). The apparent "discount" for post-2020 product is a geographic composition effect and should not be read as evidence that new construction is worth less than resale on an equivalent lot.
