Buyer Fit
Insignia Towers is the larger 2015 building, with 698 residences across 41 stories, a published HOA range of $600 to $2000+, and amenities listed in the registry as indoor pool, dog park, sky lounge, concierge, and sauna. It fits a buyer who wants a larger Denny Triangle high-rise record to review and wants to compare that scale against a newer tower before choosing a specific unit.
Spire is the newer 2021 building, with 343 residences across 41 stories, a published HOA range of $700 to $2000+, and amenities listed in the registry as pool, gym, concierge, and sky lounge. It fits a buyer who wants a newer Denny Triangle high-rise record to review and wants to compare that age and amenity profile against Insignia Towers before choosing a specific unit.
Seller Strategy
A seller in either building should make the verified facts easy for buyers to compare: unit count, year built, HOA range, amenities, floor, view, parking, and the current resale certificate. Insignia Towers and Spire share the same Denny Triangle high-rise context, so the listing has to explain the specific unit and building documents clearly rather than relying on generic tower language.
Jeff's Take
This is a clean Denny Triangle comparison because both buildings are high-rises, both are 41 stories, both publish a Walk Score of 98, and both have verified building data in the registry. The first split is age and scale: Insignia Towers was built in 2015 with 698 residences, while Spire was built in 2021 with 343 residences.
The amenity lists also overlap without being identical. Insignia Towers lists indoor pool, dog park, sky lounge, concierge, and sauna. Spire lists pool, gym, concierge, and sky lounge. Those are useful starting points, but the real decision still needs the current HOA budget, reserve study, meeting minutes, insurance information, parking details, and rules for the specific unit.
I would not choose between these buildings from the headline facts alone. Put the exact units side by side on monthly cost, floor, exposure, parking, reserves, rental policy, pet policy, and current building documents. The better choice is the unit and HOA position that underwrites cleanly, not just the newer tower or the larger tower.
