A Newly Built Oceanfront Compound in the Florida Keys With Its Own Sandy Beach Lists for $40 Million
The land was previously owned by the late naturalist Herbert Zim, the founder of the Golden Guides nature book series.

It’s the second-most-expensive listing in all of the Keys, topped by a property just down the road that’s asking $42 million.
The roughly 7-acre spread on Plantation Key was previously home to the five-house compound of the late naturalist Herbert Zim, the founder and editor in chief of the Golden Guides nature book series.

For many decades, it was both Zim’s family estate and where he produced his Golden Guides, according to the current owner, Todd Maino. He bought the property, which encompasses six parcels, from Zim’s estate, he said. Mansion Global couldn’t determine what Maino paid.
Over the course of about four years, Maino, a commercial and residential developer, transformed the property into a new compound that was completed last year. There’s a new 8,200-square-foot main house with five bedrooms and a renovated three-bedroom guest house. Maino said he left some cosmetic details unfinished to allow the next owner to personalize the home.
“They can make it their own instead of buying somebody else’s vision,” he said.

Off the main house, there’s a 120-foot pool with a hot tub, and beyond that, a sandy beach extends along the property’s 480 feet of water frontage. There’s a dock within a grandfathered-in boat basin that’s larger and deeper than what would be allowed today.
“The drag is over 6 feet, so you can have a pretty large boat there,” listing agent Angel Nicolas of the Nicolas Group at Serhant said. He and his colleague Courtney Conley listed the property a week ago.
The property is full of Florida wildlife, from osprey and sandpiper nests to peacocks that wander around.
“I actually had a manatee have a baby in the boat basin,” Maino said. “It’s ecologically balanced with nature. It’s not concrete jungle—it’s not Miami.”
Because much of the property is open land and not covered in protected trees, there’s opportunity to further develop the estate, whether that be adding another house or amenities like a tennis court or a helipad.
The main house and guest house, which stand on their own waterfront parcels, are also available for sale separately. The lot with the guest house is priced at $15 million, while the main-house lot is asking $27 million, Nicolas said.

A Name Steeped in History, A Home Built for the Future. Timeless architecture, premium residences, and an exceptional Inner West location come together at Maybelle. With construction nearing completion, buyers can move into their brand-new home by the end of the year and purchase with confidence, knowing their home is backed by 10-Year Latent Defects Insurance.
Almost a century before construction began, two sisters unknowingly inspired one of Sydney’s newest residential addresses.
Local landowner and developer John Henry Schroeder combined his daughters’ names, Isobel and May, to create Ismay Avenue, a street name that has become part of the area’s identity, still visible today in Ismay Reserve. The Maybelle borrows that story rather than inventing one. It takes its name from Isobel and May, drawing a direct line between the development and the history sitting right outside its front door.
More than simply another apartment building, it reflects a vision of creating homes that honour the past while looking confidently to the future.
Developed and built by Omaya, a family-owned company with more than 35 years of experience, The Maybelle reflects a commitment to craftsmanship, quality and creating communities that stand the test of time.
Located beside Ismay Reserve, the boutique collection of one, two and three-bedroom residences combines timeless architecture by Squillace Architects, premium interiors and exclusive resident amenities within one of Sydney’s most connected Inner West locations.
Location is one of The Maybelle’s defining strengths, residents are moments from train stations, bus services and the M4 Motorway.

Positioned just moments from North Strathfield, Bakehouse Quarter, Sydney Olympic Park, Parramatta and the Sydney CBD, residents enjoy the perfect balance of green open space, vibrant local amenity and exceptional connectivity.
Surrounded by cafés, restaurants, leading public and private schools, shopping and parklands, The Maybelle offers a lifestyle where everything is within easy reach.
Designed to embrace its unique park-side setting, many residences enjoy expansive balconies overlooking Ismay Reserve, while selected homes capture elevated views across the Sydney Harbour Bridge and city skyline.
Spacious open-plan layouts, premium fixtures and finishes, and two carefully curated interior schemes create homes that are both beautifully refined and designed for everyday living.

The lifestyle extends well beyond each apartment. Residents will enjoy exclusive access to a full-level Garden Pavilion on Level 8, featuring beautifully landscaped spaces for entertaining, recreation, remote working and gathering with family, friends and neighbours.
Complementing this is the elevated Sky Terrace on Level 14, where sweeping Sydney Harbour Bridge and city skyline views create a tranquil setting to relax, recharge and enjoy the remarkable outlook.

As both developer and builder, Omaya oversees every stage of the project – from planning through to construction – ensuring quality, accountability and meticulous attention to detail throughout.
Buyers can also purchase with confidence, knowing The Maybelle is protected by 10-Year Latent Defects Insurance, providing additional peace of mind long after settlement.
With construction nearing completion, buyers will be moving into their brand-new homes by the end of the year, offering a rare opportunity to secure a premium residence without the lengthy wait often associated with off-the-plan developments.
For those seeking more than just a new apartment, The Maybelle offers something increasingly rare – a home with an authentic story, a genuine connection to its surroundings and a lifestyle that brings together heritage, nature, connectivity and contemporary design in one exceptional address.
