| Project | Overall | Structure & systems | Management & living |
|---|---|---|---|
| Echo BrickellBrickell, Miami180 units | 9.5/ 10 | —/ 10 | 9.5/ 10 |
Google’s building-level 4.8/5 from 132 reviews sets the level and converts to 9.4/10 under the requested curve. Repeatedly reported praise about the views, amenities and staff slightly outweighs the reported concern about apartment-entry communication, producing 9.5/10 overall; no evidence supports a separate structure score. | |||
The available building review material does not establish a recurring structural defect. It does report one review mentioning leaks and one mentioning unresolved maintenance since 2026, while the building page notes elevator work in July 2026; these are isolated or administrative signals rather than a quantified recurring pattern. | Published commentary is strongly positive about daily life: one resident review calls the views “spectacular,” describes a “boutique, exclusive atmosphere” with privacy and quiet, and says the staff is attentive and service quality exceptional. The same review says the amenities are “somewhat limited” for a luxury property and that the pool and jacuzzi area is “consistently windy”; another review summary raises concern about repair access without clear advance communication. | ||
| Monad TerraceMiami Beach59 units | 8.0/ 10 | —/ 10 | 8.0/ 10 |
Google’s 4.4/5 rating from 14 reviews is the largest qualifying review base and converts to 8.2 on the requested curve. The published written feedback is predominantly positive about architecture, views, staff and valet, but the limited sample includes one serious quality-of-life complaint about balcony noise; the resulting resident-experience score is 8.0, with structure left unevidenced. | |||
The published reviews praise Monad Terrace’s design and views, including “all glass, sunlight, and water reflections” and a “Brand New luxury building.” No reviewed source located for this report published resident evidence about leaks, plumbing, HVAC, electrical systems, waterproofing, structural failures or lift reliability, so no structural deficiency is inferred. | The available Google-derived reviews describe helpful, responsive service: one reviewer says a manager and staff member were “outstanding and kind” and that he “went out of his way” to find a package; another says, “All workers are fantastic” and praises free valet. The principal lifestyle complaint was neighbor noise—dogs barking on balconies and televisions left on all day—making it difficult for one reviewer to relax and enjoy the views. | ||
| 111 West 57th StreetMidtown Manhattan, New York60 units | 7.9/ 10 | —/ 10 | —/ 10 |
The Google-derived building rating of 4.3/5 from 158 reviewers sets the level and converts to 7.0/10 under the supplied curve. Multiple written reviews praise the architecture and facade, supporting a modest upward commentary adjustment, while the small Yelp rating and the records-based Rate My Landlord score do not qualify as competing anchors. | |||
Reviews praise the facade and architecture, but one reviewer said, “Standing on the balcony is terrifying, the railing feels too low for comfort,” while another said the building may be safe by engineering standards but “doesn’t feels safe.” Separately, contemporaneous reporting on the construction lawsuit alleged HVAC-installation failures caused water damage across 10 floors; that is an old construction-period allegation, not evidence of current resident conditions as of October 15, 2026. | The building's published materials describe 24-hour doormen, a dedicated concierge, private security, a lap pool, spa and fitness facilities, but these are advertised services rather than resident review scores. The reviews read were primarily about architecture and perceived safety; they did not provide reliable current evidence about management response times, staff attitude or common-area upkeep. | ||
| The FitzroyWest Chelsea, New York14 units | 6.5/ 10 | —/ 10 | 6.1/ 10 |
The largest published review base located was the building-specific 3.7/5 aggregate from three reviews, which converts to 6.1/10 on the supplied curve. Because the review base is below ten, the result remains close to the prescribed 6.5 no-anchor threshold; structure is left unscored because no published structure rating was found. | |||
The resident-review page contains positive physical comments, including “Excellent building and finishes. Best I’ve seen in NYC.” Separately, October 2025 reporting on the condo-board lawsuit described allegations of empty rooms instead of wine cellars, improperly installed cellar drains, leaking sinks and floors, and dryers that “routinely malfunction”; the sponsor disputed the claims as “entirely without merit,” so these are allegations rather than adjudicated findings. | One August 2024 review said there was “Great new staff and very professional” service, while a September 2022 review alleged a “Terrible DOORATTENDANT” and said the building “COULD USE BETTER STAFF!” October 2025 reporting also described the board’s allegations that common amenities were unfinished or non-working, including bathrooms, laundry facilities and saunas; the sponsor denied the lawsuit’s merits. | ||
| The Brooklyn TowerDowntown Brooklyn, New York | 6.1/ 10 | —/ 10 | 6.1/ 10 |
Google Reviews/Maps provides the largest clearly stated review base and reports 3.8/5 from 116 reviews, converted to a 6.4 anchor on the requested curve. The reported themes move that level slightly downward overall: construction, elevator/access, noise and management complaints are balanced only partly by praise for design, cleanliness and responsive staff. Current status remains somewhat uncertain because several detailed operational reports were published in 2025, while the Google material includes reviews through March 2026. | |||
Published resident and reporting-based feedback describes noisy, vibrating elevators that can stall, along with “cracks and chips in floor tiles and staircases,” peeling grout and paint, and malfunctioning intercoms and FOB keys. A resident also reported “weird noises the building makes when it’s very windy” and “things falling apart in your apartment”; these are reported complaints rather than an engineering assessment. | Daily-life feedback is sharply mixed. One resident praised management as “incredibly communicative” and said the concierge confirmed move-in details, while another said staff were terrible and that continuing construction meant they could “barely sleep”; a March 2025 resident also said, “none of the amenities have opened yet.” | ||
| American Copper BuildingsManhattan, New York761 units | 6.0/ 10 | 5.8/ 10 | 6.1/ 10 |
The Birdeye/Google aggregate of 3.7/5 from 371 reviews is the anchor and converts to approximately 6.1/10 under the requested curve. Openigloo’s 3.8/5 from 14 reviews is directionally consistent and does not create a material dissent. The reported complaints produce a modest net downward adjustment, partly offset by repeated praise for staff, cleanliness and amenities; the 2026 public-record issues are treated as commentary evidence, not as a separate rating. | |||
Resident feedback includes “severe vibration from HVACs,” humming and drumming in the walls, and a report that the floor was sloped; these are individual resident allegations rather than verified engineering findings. Public building records also show 2026 ventilation, window/floor and bathtub/shower complaints, while the older CityRealty description says the site’s flood exposure led to mechanical equipment being placed on the second floor with floodgates and backup generators. | The strongest positive pattern is staff and upkeep: residents describe staff as “attentive,” “kind” and “professional,” and one former resident says the building was “consistently clean and well cared for.” The negative accounts focus on responsiveness, costs and comfort: reviewers mention “no response to emergency issues,” expensive gym/rooftop access, noise and pest concerns; Birdeye also carries a complaint about “Terrible doormen” failing to stop skateboarding in the front area. |
