From the listing
Proudly introducing a spectacular new construction residence by Mizner Development, with anticipated completion in Late Summer 2027. Ideally situated in the charming neighborhood of Palm Beach Farms, the home is located within one of Boca Raton's most sought-after school districts and just steps from the neighborhood park that anchors the community. Designed in a refined coastal-contemporary style, this exceptional residence offers a thoughtfully curated floor plan that seamlessly blends indoor and outdoor living. The open-concept kitchen overlooks the dining room and expansive great room, while a fully equipped back kitchen provides additional preparation and storage space for effortless entertaining. The ground floor also features a well-appointed clubroom and a flexible fifth bedroom or private home office. Outside, a resort-style pool and spa are surrounded by generous lawn space and lush landscaping, creating a private and tranquil setting. An approximately 500-square-foot covered patio with a full outdoor kitchen provides the perfect environment for year-round dining, entertaining and relaxation. From the foyer, soaring double-height ceilings create an impressive sense of arrival and lead to the second floor, where an oversized loft is accompanied by three spacious guest suites—each featuring an ensuite bathroom and walk-in closet. Privately positioned in its own wing, the expansive primary suite offers two oversized walk-in closets and a spa-inspired bathroom designed as a serene personal retreat. Combining modern architecture, exceptional functionality and a premier Boca Raton location, this newly built residence presents an extraordinary opportunity in the heart of Palm Beach Farms.
Monthly payment calculator
Rate: 7.24% 30-year fixed average (Freddie Mac, week of October 29, 2026). Your own rate may differ; you can change it here.
Estimate, not a loan offer. Tax default: the higher of the seller's bill and about 1.9% of price (Florida resets a new owner's assessment). Insurance default: Florida OIR county average with wind, data as of Mar 31 2026. Rate is an assumption; your lender sets the real one. Zach doesn't take lender or title referral fees.
Florida risk facts
- Flood zone
- Zone X: minimal flood hazard (per FEMA map). Outside FEMA's mapped high-risk area. Many flood claims still come from outside high-risk zones, so a quote is worth getting. Source: FEMA National Flood Hazard Layer, checked Oct 31, 2026. This is a map lookup, not an official flood zone determination.
- Wind and building code
- Built in 2027, after the statewide Florida Building Code took effect in 2002. Ask for the wind mitigation report; it can lower insurance. My Safe Florida Home offers free inspections and grants when funded.
- Disclosure
- Florida sellers must give you a flood disclosure about known flood damage, insurance claims and federal assistance (§689.302).
We don't show crime scores or rate neighborhoods. Every listing is open to everyone.
Start an offer
- Pre-approval letter or proof of funds (cash)
- The price you'd offer and your deposit
- Financing type and closing date
- Inspection period you want (often 10-15 days)
- A signed buyer agreement with Zach (Florida practice before touring or offering)
Nothing here is a binding offer. Zach calls you, checks the comps and writes the contract with you.
