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.
