About this home

Welcome to 638 Lakeside Harbor, one of South Florida's most forward-thinking new builds — a move-in-ready 4BR/4.5BA coastal retreat east of US-1 in a gated enclave of only 10 homes. Designed by Blue Oval Group and pending certification as one of Florida's first iPHA Passive Homes, it pairs contemporary luxury with future-forward construction, Intracoastal and canal views, water and dock access, and a private community beach. Inside: soaring ceilings, large-format tile, a two-story glass staircase, private elevator, and a chef's kitchen with Dacor and Bosch appliances and a marble island overlooking a living room with statement fireplace. Every bedroom is en-suite; the primary offers a balcony, freestanding tub, water closet, dual vanities, and walk-in closet, while a main-level bedroom doubles as an office or den. A loft, second-floor laundry, smart controls, impact glass, air/water purification, soundproofed walls, an efficient HVAC-ERV system, whole-home generator, dual EV chargers, and solar-ready infrastructure add peace of mind. Outside: a decked patio and separate covered patio overlooking a saltwater pool and waterfall, plus a spiral staircase to a rooftop terrace with summer kitchen and Intracoastal views. Storm-resilient construction and hypoallergenic, mold- and pest-resistant materials — with an estimated 90% energy-cost reduction — deliver a smarter way to live. Minutes from Oceanfront and Oyer Park, Boynton Harbor Marina, Atlantic Avenue, and PBI.

Before You Make an Offer

Buying new construction from a builder

Your Buyer May Already Be Working With BreakThru Realty

Buyers come to BreakThru Realty searching for homes like this one, and many have shared their exact requirements with us: the neighborhood, the price, the bedrooms, the pool, the timing. If you own a home nearby and are weighing a sale, a broker can check it against those requirements before you list, and if no buyer on file fits, show you how we would reach the rest of the market.

BreakThru Realty works with hundreds of prequalified buyers searching for properties. Before you list, a broker reviews what you own, the market around it and whether an existing buyer's requirements match. If none does, you see how we would position it to reach other qualified buyers.

A potential match is a conversation, not an offer, until the buyer sees your property and makes one. No buyer is named and nothing about your property or business is shared until you decide to proceed.
