One Twenty Brickell Residences: Reservation-to-Closing Timeline Explained

One Twenty Brickell Residences is a Property Markets Group (PMG) tower at 120 SW 8th Street in Brickell. Its official materials name Sieger Suarez Architects as architect and Cotofana Designs as interior designer. REHUB Miami's 2026 guide to the project also lists Juneau Construction Company as general contractor. The same guide describes a 37-story tower with 266 furnished residences in studio, one-, two- and three-bedroom layouts, ranging from about 450 to 1,395 square feet.

Those figures differ from the project's earlier launch specification. PMG's portfolio page describes a 34-story tower with 240 residences, and REHUB Miami's 2026 guide notes the same 34-story, 240-unit launch spec for 2024 before the program grew. Both PMG's portfolio page and REHUB Miami's guide describe the building as sold out. For a family reading this guide, the practical meaning is that the pre-construction sequence below is most useful as a framework for understanding how the building was sold and what remains ahead. The path to a unit today may run through the second-phase Signature tower or through a transfer from an existing buyer, and the sales team can confirm what is actually available.

The project is also under construction rather than a concept. According to REHUB Miami's 2026 guide, the construction timeline runs toward 2028. We treat that as a reference point rather than a promise, because the guide itself frames the schedule as a published program. Any family planning around a move-in date should ask the developer for its current written estimate.

A typical path, as outlined in a Brickell pre-construction guide from The Miami Home Group, runs from reservation to contract, then staged deposits during construction, then a certificate of occupancy and closing. The reservation is the earliest and lightest-commitment step. CondoBlackBook's pre-construction guide describes this phase as offering the lowest early-bird pricing and a wider selection of units, while noting that some building details may change and some unknowns remain.

For a multi-generational household, this is the stage where the real work is internal rather than contractual. Before a unit is chosen, the family should agree on who will live there full time and who will visit. They should also settle whether the home is a primary residence, a shared base or a secondary home, and what each adult needs from the space. That conversation matters in a building with this particular design. According to the developer's official site, each residence includes a private, dedicated office suite, and REHUB Miami's guide says the deeded office can reach up to 387 square feet.

That office suite is separate from the residence itself, which changes how a family can divide space. A parent who works remotely, a young professional or a grandparent who wants a quiet room can each have a defined area. Think through those uses early, because the unit mix runs from studios to three-bedrooms and the right size is a household decision, not a price decision.

CondoBlackBook's guide says the contract stage typically arrives three to six months after the reservation phase begins, once the developer has completed the approvals needed to go under contract on its units. After that, the Miami Home Group guide describes staged deposits made during construction rather than one large payment at the start.

The developer's own marketing for One Twenty Brickell Residences describes a staged payment plan that places the largest portion at closing and the earlier portions at contract, shortly after contract, at groundbreaking and at the one-year mark. The page is undated, so we do not repeat the exact percentages here. Families should request the current schedule in writing from the sales team and confirm which milestones have already passed.

With several family members contributing, a shared calendar of deposit milestones is more useful than a general sense of the total. Decide in advance who is responsible for each date and how the family will communicate if a milestone moves. The Miami Home Group guide also advises reviewing the contract's definition of substantial completion and any delay allowances, which is the kind of detail every contributing member should understand before the first deposit date arrives.

Construction is the longest stage and the one where families most often lose track of the calendar. The Miami Home Group guide notes that timelines vary with tower scale, foundation type, supply chains, weather and inspections. It recommends staying in touch with the sales team throughout, asking for milestone updates and revised closing estimates, and asking how final finishes and punch lists will be handled.

That advice suits a tower of this size. The published program, which REHUB Miami's 2026 guide puts at 37 stories, is a substantial build, and the guide notes the amenity program is concentrated on levels 12, 14 and 36. The developer's materials describe more than 60,000 square feet of amenities, including an infinity-edge pool, a pickleball court, a sky bar and lounge, a wellness and fitness center, and a kids' club. Because those spaces are among the last to be finished and tested, it is reasonable to ask the sales team how amenity completion is sequenced relative to the certificate of occupancy.

A useful habit for a family is to designate one person as the point of contact with the sales team. That person can circulate updates to everyone else, rather than having several relatives asking the same questions and receiving slightly different answers. Keep a simple log of dates, estimates and who said what, so a revised schedule can be compared with the original.

The certificate of occupancy is the turning point. CondoBlackBook's guide explains that once the developer receives the certificate from the county, which permits people to begin residing in the property, the developer sends out letters requesting closing within 30 days. The guide adds that you can schedule your move-in date once you have closed on your unit.

That 30-day window is short relative to a multi-year build, and it is the main reason to plan the family's logistics well before the letter arrives. If several households are consolidating into one residence, a prompt closing may coincide with the sale or lease-end of other homes. Work backward from the likely closing window and ask the sales team how much notice the developer expects to give.

Closing is also when the transition to ownership begins. The Miami Home Group guide recommends confirming how punch lists will be handled, which is worth a conversation before the walkthrough rather than during it. Because the residences are delivered fully finished and furnished, according to REHUB Miami's 2026 guide, the walkthrough is partly an inspection of finishes and furnishings. Bring the family member who will use the space most, and take photographs of anything that needs follow-up.

The developer's official Signature site describes One Twenty Brickell Signature Residences as the next chapter of the vision introduced with One Twenty Brickell Residences, with a private office suite included in each residence. The site presents a design-forward approach that balances work, wellness and home, and places the building near Brickell City Centre and The Underline. REHUB Miami's guide also discusses how the second-phase tower fits in. Families interested in this address who find the first tower unavailable may want to ask the sales team about the Signature phase and its own schedule.

A few planning questions apply to either tower. Ask for the current written construction estimate and how it has changed since launch. Ask which unit layouts and sizes remain, and whether the family's priorities, such as separate sleeping areas and a dedicated office for each working adult, can be met within the available mix. Ask who the contractor, architect and property manager are, as the Miami Home Group guide suggests, and review the developer's track record on completed projects.

Finally, build slack into the family calendar. Construction schedules can shift, and a household that has already given notice on another home is more exposed than one with flexibility. A realistic plan treats the published timeline as a target, keeps a buffer on both sides, and revisits the plan each time the developer issues a revised estimate.
