Downtown vs Denny Triangle High-Rise Comparison
Emerald and Spire are two of the newest condo towers in the Seattle core, both completed in 2021 and both rising about 40 stories over the urban grid. The real decision is not the height. It is which side of the core you want to live on, Emerald's Pike Place and waterfront-facing Downtown address versus Spire's Amazon-adjacent Denny Triangle position, plus unit count, in-building resale competition, and how a specific unit sits in its stack.

Buyer Fit
Emerald is a 40-story tower at 121 Stewart St with 262 residences, completed in 2021 in the heart of Downtown, steps from Pike Place Market, the Seattle Art Museum, and the Elliott Bay waterfront. Its 262-unit count is the tighter of the two, which can mean less in-building resale competition when you go to sell. It fits a buyer who wants to be in the classic Downtown core, walking distance to the market, the waterfront, and the financial district, in recent construction.
Spire is a 41-story high-rise at 2510 6th Ave with 343 residences, developed by Laconia Development and also completed in 2021. It sits in Denny Triangle between Downtown, South Lake Union, and Belltown, carries a Walk Score of 98, and lists published pricing from $700K with HOA dues ranging from $700 to $2000+ per month. With a documented amenity set including a pool, gym, concierge, and sky lounge, it fits a buyer who wants the Amazon and SLU employment cluster at the doorstep and a full amenity package in the building.
Seller Strategy
The seller decision splits on location and scale. An Emerald seller competes against a smaller in-building pool of 262 units and leads with the Downtown core position, the Pike Place and waterfront proximity, and the specific unit's view orientation. A Spire seller has 343 units in the tower and a larger amenity story to tell, but competes inside Denny Triangle against newer-tower alternatives like Nexus a block away, so timing around active and pending units in the building matters more. In both towers, the winning listing leads with the specific unit's stack, floor height, view, and current HOA position, not with generic new-construction language.
Jeff's Take
On paper these look like the same era of building: two roughly 40-story Seattle towers, both delivered in 2021, both in the walkable core. They are not the same decision. Emerald puts you in Downtown proper, steps from Pike Place Market and the Elliott Bay waterfront. Spire puts you in Denny Triangle, at the edge of the Amazon and South Lake Union job center. Where you want to walk out your front door is the first and biggest fork.
After that it comes down to scale and what is documented. Spire is the larger building at 343 units, with a published amenity set, a Walk Score of 98, and pricing and HOA ranges on the record, which gives a buyer more to underwrite up front. Emerald is the tighter 262-unit tower in a more central Downtown address, which can mean less in-building resale competition down the line. Neither wins on the floor plan of a brochure. The better-positioned unit in either tower beats the weaker unit in the other, every time.
Before you choose, I put the two specific units side by side on view orientation, floor height, monthly cost per square foot, parking, and the current HOA reserve and assessment position. That comparison, not the marketing, is what tells you which building is actually the better buy for you.
