Seventeen residences. That is the whole pitch at One Bay Harbor — a seven-story boutique at 1150 101st St where the elevator serves so few homes that neighbors actually know each other. Completed in 2019 by Tross International and designed by Frankel Benayoun Architects, the building mixes one- to three-bedroom residences (955 to 1,972 square feet) with a rooftop pool, fitness center, and a duplex penthouse crowned by a wraparound terrace. Resale and rental listings both surface at One Bay Harbor, and the rental rules deserve a close read before you buy — they are stricter than a certain resale listing's marketing suggests.
One Bay Harbor Frequently Asked Questions
❯ How many units are in One Bay Harbor?
Seventeen, across seven stories — ten one-bedrooms, five two-bedrooms, and two three-bedrooms, plus the duplex penthouse. It is one of the smallest purpose-built luxury buildings on the island, which means amenities like the rooftop pool and fitness center are shared among very few households.
❯ What is the rental policy at One Bay Harbor?
The HOA's published policy allows leasing twice per year with a six-month minimum, and owners may lease during the first year after purchase. Note: at least one resale listing marketed the building as short-term friendly, which conflicts with the published long-term rules — verify the current policy in the condo documents before buying.
❯ Tell me about the penthouse.
The PH702 duplex corner penthouse spans about 1,972 square feet with four bedrooms and three and a half baths, wrapped by a private terrace built for sunset entertaining — plus a spa-like sauna room and a fully kosher kitchen.
❯ What amenities does the building have?
A rooftop pool with panoramic views, a jacuzzi, a fitness center, ample storage lockers, and two assigned parking spaces per residence. The amenity set is compact but complete — everything a 17-residence building needs, nothing it doesn't.
❯ Can you walk to Bal Harbour Shops from One Bay Harbor?
Steps from the Bal Harbour Shops, top-tier schools including the A-rated Ruth K. Broad Bay Harbor K-8, houses of worship, and the beach. Walkability is a genuine selling point — the car can stay parked for days.
❯ What sizes do the residences come in?
From about 955 square feet for the one-bedrooms up to 1,492 square feet for the three-bedrooms, with the duplex penthouse at roughly 1,972. Floor-to-ceiling windows and wraparound balconies make even the smaller plans live larger than the numbers suggest.

Life in a Seventeen-Home Building
There is a texture to buildings this small that no amenity deck can replicate. Seventeen households means the board knows every owner, packages don't pile up, and the rooftop pool at golden hour feels like a private club. One Bay Harbor was clearly designed for buyers who have lived in big towers and decided they were done with them.
The one-bedroom-heavy mix makes this an accessible entry into newer island construction — resales from the mid-$600s into seven figures. For an even smaller boutique, Pearl House has just 15 residences; for a 36-unit alternative, see Bay Harbor One.
The Penthouse Sets the Tone
Every boutique needs a flagship, and at One Bay Harbor the duplex penthouse is it. Four bedrooms, three and a half baths, a wraparound terrace with sunset views, and bespoke touches like the sauna room signal what the developer thought the building's ceiling could be — and resale pricing for the best units has largely validated it.
Below the penthouse, the formula stays consistent: modern design, floor-to-ceiling glass, and terraces that pull the outdoors in. It is not the flashiest building on the island, but seventeen households seem to like it that way. Another Frankel Benayoun design worth comparing: Onda Bay Harbor on the east waterfront.
