A six-story condominium community on Alki Avenue, across from the public shoreline, with a pool courtyard and hillside backdrop.
1250 Alki Avenue SW · Alki · Seattle
Building note: The developer announced temporary occupancy approval in December 2022. The first closing occurred in June 2023, and completed-project reporting followed that year. The May 2018 design-review proposal contained 40 homes; the completed community contains 37. Construction approval, occupancy and sales dates represent different milestones.
Between the bluff and the bay: the making of Infinity Shore Club
At 1250 Alki Avenue SW, Infinity Shore Club approaches waterfront living through the width of its site and the arrangement of its outdoor rooms. Its 37 condominiums occupy six stories, with a steep green hillside behind and the public shoreline across the avenue. Vibrant Cities developed the project, Tiscareno Associates designed the architecture, Susan Marinello Interiors shaped the interiors, and Walsh Group built it. The result reflects a particular piece of Alki geography, with the building's form, materials and shared spaces all responding to the setting.
An infinity pool gives the central courtyard its purpose
The pool sits in the opening between the residential wings, alongside a sun deck and a glazed residents' lounge. A cascading water wall brings the composition down to street level, where pedestrians can experience it from outside. That central opening is the architectural gesture that makes the broad development legible as two connected parts.
Assembling the site
Five parcels became one carefully divided building
The May 2018 design-review packet called the proposal Alki Beach Residences and described five parcels near Duwamish Head. It showed forty homes; the completed community contains thirty-seven. The packet also reveals how the design was conceived around two landscapes: Puget Sound in front and the wooded slope behind. A courtyard facing the water and a rear garden terrace were connected visually through the lounge. These were organizing ideas from the planning process, giving residents places to experience both sides of the property rather than treating the hillside as merely the back of a building.
Architecture shaped by constraints
A curved avenue and a steep slope set the terms
Tiscareno describes a site squeezed between the hillside and Alki Avenue's curve, limiting the footprint and parking options. Splaying the building into two wings followed that curve while breaking down its apparent size. Two elevator cores serve the separated volumes. Bob Tiscareno also described meetings with neighbors and additional side setbacks intended to bring more daylight and landscaping between buildings. The finished form is therefore more than a way to capture views. Its divisions, openings and edges address the challenge of fitting a relatively broad condominium project among the surrounding waterfront buildings.
Behind the open interiors
Concrete structure and acoustic details support the design
Structural engineer Scott Erickson of DCI Engineers explained that concrete allowed the team greater freedom in arranging columns, walls and open living areas. Those decisions supported the extensive glass and projecting balconies envisioned by the designers. Acoustic consultant Mohamed Ait Allaoua of A3 Acoustics described another set of less visible choices: double-stud party walls, cast-iron waste and rainwater piping, and attention to mechanical noise and vibration. The value of this account lies in its specifics. It explains how the project team approached spacious interiors and sound control, while leaving actual performance to be assessed in the residence itself.
An interior designer's connection to Alki
Susan Marinello drew the palette from a familiar beach
For Susan Marinello, the location was personal. In a project interview, she recalled attending Alki Elementary for three years and visiting a grandmother who lived in the neighborhood. Her material choices followed that familiarity: warm hardwood, stone and tile intended to recall the sand, pebbles and water outside. She described a deliberately restrained palette, allowing a smaller number of materials to carry the rooms. That approach gives the interiors a connection to the beach without turning them into a collection of nautical references. When comparing homes, look at how the finishes meet the daylight and outlook of the particular floor plan.
Different kinds of outdoor space
The shoreline, the shared gardens and the private terrace
Infinity's exterior life happens at several scales. The public shoreline is across Alki Avenue. Within the development, the published amenity program includes the pool and heated spa, a rear garden retreat, rooftop gathering areas, a fitness center, and equipment storage and washing facilities for water sports. The architect distinguishes communal roof areas from private ones, an important detail when looking at a particular residence. Folding glass NanaWall systems connect indoor rooms with decks, but a home's outdoor area, exposure and privacy still need individual comparison. Walk the shared spaces as well as the apartment to understand the whole setting.
The opening came in stages
Construction completion and the first closing tell different parts of the story
The developer's occupancy announcement records a January 30, 2020 groundbreaking, just before the pandemic. In December 2022, the project announced a temporary certificate of occupancy and anticipated residents arriving the following January. The first closing came later: a June 2023 announcement identified June 12 as the initial completed sale after resolution of a contractor dispute. Those milestones explain why a 2022 construction date and a 2023 opening account can both appear in the building's history. Infinity was newly built as condominiums, and its transition from construction into ownership unfolded over more than one calendar year.
