Bosa Development's twin-tower campus — North and South, sharing one amenity platform.

Insignia was developed by Bosa Development — the same firm behind Bellevue Towers and Washington Square in downtown Bellevue. The South Tower delivered in 2015, the North Tower in 2016. Together they form one of Seattle's largest luxury condominium campuses at approximately 560 combined residences. Both towers share a single amenity platform including one of the only outdoor heated pools in any Seattle luxury condominium building.

Amenity stack

Outdoor heated pool, concierge, and a full fitness studio — shared across both towers.

Insignia's amenity campus is among the most complete in Seattle luxury condo buildings. The outdoor heated pool is the headline feature — rare in Seattle's urban high-rise market. Residents from both the North and South Tower have full access to the shared platform, which includes the pool, concierge, fitness center, club room, theatre, and outdoor terraces.

View orientation

Puget Sound to the west. Lake Union to the north. Rainier to the south.

Insignia's 41-floor North Tower height and Denny Regrade position create a panoramic view footprint. West-facing North Tower upper floors command the highest premiums; South Tower units offer the same orientation at lower absolute price points due to its 26-floor height. RexMont maps each tower's per-square-foot spread by floor and direction before any offer.

West (North Tower premium)

Puget Sound, Olympic Mountains, Elliott Bay, Bainbridge Island

The North Tower's full height (41 floors) unlocks the most unobstructed westward Puget Sound and Olympic Mountain views in the building. Upper north-tower west units are the building's most sought-after at resale, commanding the highest price-per-square-foot in the Insignia comp pool.

North

South Lake Union, Lake Union, Queen Anne, Cascade foothills

Lake Union views from north-facing North Tower units. The South Tower's lower height means upper north-facing floors in the North Tower have meaningfully better sight lines across the SLU corridor and toward Queen Anne.

East

Cascade Mountains, Capitol Hill, South Lake Union, downtown core

Morning Cascade views — an entry price point inside the building. Same outdoor pool, concierge, and amenity access as west-facing floors at a lower per-square-foot cost. South Tower east-facing units offer this view angle at a lower absolute price.

South

Downtown Seattle skyline, Pioneer Square, Mount Rainier

Upper south-facing floors in both towers frame Mount Rainier and the full downtown skyline. South Tower upper floors offer this view at a lower entry point than comparable North Tower units. A popular orientation for buyers who prefer the city-and-mountain framing.

Location & commute

Denny Regrade: equidistant to Amazon, Pike Place, and Seattle Center.

Insignia's position in the Denny Regrade puts Amazon headquarters, Pike Place Market, and Seattle Center all within a 10–12 minute walk. Westlake Link Light Rail is 8 minutes on foot, giving residents access to the broader Sound Transit system without a car.

Why work with RexMont

Two towers. Nine years of comps. We know every floor in both buildings.

Insignia is one of Seattle's most data-rich luxury condo buildings — two towers, 9+ years of resales, and enough transaction volume to price precisely by floor, orientation, and tower. RexMont's Insignia comp database is the most granular tool available to buyers and sellers in this building.

Twin-tower structure means genuine optionality on floor, height, and price

Most Seattle luxury condo buildings are a single tower — Insignia gives buyers a real choice. The North Tower (41 floors) and South Tower (26 floors) share the same amenity campus, developer pedigree, and HOA but have meaningfully different price-per-square-foot curves. Buyers who want upper-floor Puget Sound views target the North Tower; buyers who want the same Bosa-quality finishes and amenity campus at a lower entry point often find their value in the South Tower. RexMont maps both towers' comp data before any offer.

Bosa Development's construction quality commands a consistent resale premium

Bosa is one of North America's most respected luxury condo developers — the same firm behind Bellevue Towers and Washington Square. Buyers who prioritize construction quality, finish standards, and long-term build integrity consistently look at Bosa buildings first. Insignia's resale comp pool reflects a sustained premium relative to buildings from less rigorous developers.

Established comp pool means buyers and sellers price with real data

Insignia delivered in 2015–2016, which means more than 9 years of resale data. Unlike Spire's thin comp pool, Insignia buyers and sellers have access to hundreds of closed transactions across both towers — enough to price by floor, orientation, and specific floor plan within each tower. RexMont's database of Insignia comps is detailed enough to show exactly where value sits inside the building.

Outdoor pool is rare in Seattle luxury condo buildings

Insignia has a heated outdoor pool — a feature that appears in very few Seattle luxury condo towers. For buyers who prioritize resort-quality amenities in an urban setting, Insignia is often the first building they land on. The pool is also a meaningful marketing differentiator when Insignia units are listed: it draws buyer attention in a market where most competing towers offer only indoor fitness amenities.

Selling at Insignia

Bosa quality, an outdoor pool, and Puget Sound views — the story sells itself if told right.

Insignia sellers have three headline assets: Bosa's construction reputation, the outdoor heated pool, and the North Tower's Puget Sound view angles. Every RexMont listing strategy for Insignia leads with those three and targets the specific buyer pools most likely to pay a premium for them.

North Tower height advantage — 41 floors with unobstructed Puget Sound and Olympic Mountain views is the Insignia seller's strongest headline, and upper-floor west-facing units command the most competitive market
Bosa Development brand recognition — buyers who research Seattle luxury condos know Bosa's construction quality, and the developer name carries direct pricing credibility in listing copy
Outdoor heated pool in photography — one of the only Seattle luxury condo towers with this feature; lead with it in listing media
Deep comp pool supports precise pricing — 9+ years of resale data means pricing conversations are anchored in fact, not guesswork, which shortens negotiation cycles
Twin-tower optionality as a value narrative — South Tower units can be positioned as the same Bosa build and campus at a lower price point, broadening the potential buyer pool
Denny Regrade location — equidistant to Amazon HQ, Pike Place, and Seattle Center; a compelling walkability story for multiple buyer segments

FAQ

Insignia Seattle questions buyers ask us most.

How many towers does Insignia Seattle have?

Insignia Seattle has two towers — the North Tower (41 floors) and the South Tower (26 floors). Together they have approximately 560 condominium residences. Both towers share the same amenity campus, developer (Bosa Development), and HOA structure. The North Tower offers the greatest height and the building's most commanding Puget Sound and Olympic Mountain views; the South Tower offers the same Bosa quality and shared campus at a lower per-square-foot entry point.

Who developed Insignia Seattle?

Insignia was developed by Bosa Development — a Canadian-based luxury developer with a significant presence in the Pacific Northwest. Bosa also developed Bellevue Towers and Washington Square in downtown Bellevue. Bosa buildings carry a consistent resale premium in both markets due to the developer's reputation for construction quality and finish standards.

What are the views like at Insignia Seattle?

The North Tower's 41-floor height delivers the building's most dramatic views — upper west-facing floors have unobstructed Puget Sound, Olympic Mountain, and Elliott Bay exposure. North-facing units look over South Lake Union and Lake Union toward Queen Anne. East-facing floors show the Cascade range. South-facing upper floors frame downtown Seattle and Mount Rainier on clear days. South Tower views follow the same orientation pattern at lower maximum heights.

Does Insignia Seattle have a pool?

Yes. Insignia has an outdoor heated pool — one of very few Seattle luxury condo towers to offer this amenity. The pool is part of the shared amenity campus between both towers and is available to all Insignia residents. This feature is consistently a differentiator at resale for buyers who prioritize resort-quality outdoor amenities in an urban high-rise.

What is the HOA fee at Insignia Seattle?

Insignia HOA dues vary by unit size, floor, and whether the unit is in the North or South Tower. As a building delivered in 2015–2016, the HOA has had nearly a decade to build reserves and conduct multiple reserve studies. RexMont reviews the current HOA budget, reserve study, and per-unit contribution rates before any Insignia offer.

How does the North Tower compare to the South Tower at Insignia?

The North Tower (41 floors) reaches higher, which delivers better sight lines for upper-floor units — particularly on the west side where Puget Sound and Olympic Mountain views are unobstructed at height. The South Tower (26 floors) offers the same Bosa construction quality, the same shared amenity campus, and the same HOA at a lower per-square-foot entry point on equivalent floor plans. The best choice between the two depends on budget and whether unobstructed top-floor views are a priority.

Is Insignia Seattle close to Amazon headquarters?

Insignia is an 8–10 minute walk to Amazon's Day 1 building and the Spheres — farther than Nexus (4–6 minutes) but still within comfortable walking distance for daily commuters. Insignia competes with Nexus for the Amazon employee buyer pool primarily on the strength of its outdoor pool, twin-tower optionality, and deeper comp-supported pricing.
