The tower went up in 15.5 months. The harder number is six.
That’s how many months Coastal Construction has been running full-scale high-rise work next to occupied condominiums. The south tower at Saltleaf on Estero Bay opened in March 2026. The north tower topped out on 23 September, 22 storeys, 838,335 square feet, with residents living forty feet away through the whole concrete cycle.
The two towers carry a $458 million construction value inside a $750 million development spread across 500 acres of Southwest Florida coastline. London Bay Development Group is the developer. Arquitectonica is architect, McNamara Salvia structural engineer.
What’s underneath it
Deep auger-cast piles and post-tensioned concrete, which is the standard answer on a bay-front Florida tower and has been a more closely examined answer since Surfside. Large-format glazing and extensive balconies sit on top of that, which sets the tolerance regime: a curtain wall of that scale doesn’t forgive a deck that drifted.
Getting 838,335 square feet from start of construction on 10 June 2025 to top-out on 23 September 2026 means the concrete cycle held through two Florida summers. Temporary certificate of occupancy is targeted for 31 May 2027, final CO for 27 August 2027. Both are targets.
The occupied-neighbour problem
Brion Salatino, a senior project manager at Coastal, described the constraint as maintaining “full-scale construction operations while protecting resident access and safety.” That’s the polite version of a logistics plan where the crane radius, the delivery route, the concrete pump setup and the hoist all have to work around people who are home.
Developers phase two-tower projects this way for good financial reasons. The first building delivers, closes and pays down debt while the second is still forming decks. What it costs is a two-year period where the construction manager’s site rules are also a customer-service commitment, and where a dropped tool is a very different event than it would be on a fenced site.
The numbers, and where they come from
The subcontractor list is deep: Allen Concrete on concrete and masonry, Power Design on electrical and HVAC, American Plumbing, Coastal Fire Protection, Stowell, Sigma Marble & Granite, Stone Systems and Spectrum Kitchens.
The $458 million and $750 million are developer and contractor figures reported by ENR. There is no public filing behind either, the square footages are as supplied by the project team, and the 2027 certificate dates are objectives rather than commitments. Everything in this project’s public record traces back to the people building it, which is normal for private residential and worth stating anyway.
Twenty-two storeys, 224 units, two towers. One of them has people in it.
