Two suns.
One hill.

One of the city's first neighborhoods. Victorian porches, old trees, the southeast corner of Balboa Park. Named for the hour the setting sun reaches it after downtown has gone to shadow.

Alüm takes the crest of 25th and C and builds for that hour: tall glass, planted balconies, shops on the sidewalk, a roof for the end of the day. One hundred and thirteen homes. One hill.

    Level 1

    Arrival

    Walnut, dark tile, a patterned stone floor. A leather bench. A ceiling made of light. The first room a guest remembers.

    Level 7

    The pool

    Long and narrow, for swimming. Olive trees in terracotta. Loungers for after, a table under the pergola for after that.

  • Rendering of the dining and lounge room: a long oak table, a green sofa, a wall of timber cabinetry and a stone-topped kitchen counterPlate V
    Level 7

    The dining room

    One table for twelve. A kitchen behind it, a sofa beside it, a screen for the match. Sunday, if it goes long.

  • Rendering of the lounge: a deep green sectional facing glass doors that open to a terrace table and the skyPlate VI
    Level 7

    The lounge

    Glass walls that slide away. Inside and out become one room, most days of the year.

    Level 8

    Panorama Bar

    Warm timber, a softly lit bar and lounge seating by tall windows. A room for conversation, listening and the last light of the day. The Level 7 Resident Terrace is for all residents; additional Level 8 club experiences require a separate paid membership. Explore Panorama Bar for the distinction; programming and availability remain subject to change during construction.

The hill,
the park,
the city.

Coffee on 25th Street. The park at the end of it. Downtown at the bottom of the hill.

Golden Hill marks the southeast corner of Balboa Park and holds the oldest public golf course in San Diego. The ballpark, the Gaslamp and the bay are a few minutes west. Close enough to use. Far enough to leave.

Golden Hill
Morning25th St

The street

A roaster, a supper club, a slice, a bistro. Three blocks.

AfternoonBalboa Park

The park

Golden Hill Park, the golf course, the Pershing bikeway. All of it begins where the neighborhood ends.

EveningDowntown

The city

East Village, the Gaslamp, the water. Down the hill and back up for the light.

IV ArchitectureCAST Development
ALÜM exterior rendering with planted balconies above the corner storefront.

Built for
the hour.

Deep, planted balconies over a corner of shops. A patterned screen at the sidewalk. A terrace on seven for the end of the day.

The building is a mixed‑use residence by CAST Development. Its face to 25th Street is a grid of balconies thick with planting, so the view turns green before it turns to city; its ground floor opens to the sidewalk behind a perforated screen. The graphic identity follows the building rather than decorating it: the vertical of the tower, the disc of the sun, the paper‑and‑ink of the elevations.

V The name

Golden Hill · Two suns
I · 1887

Golden Hill

Seen from the water at dusk, the setting sun caught the glass on the hillside and turned the neighbourhood into a beacon. Schuyler and Bartlett named it for that light.

Schuyler & Bartlett1887
II · 25th & C

Alm

Alüm is named for Golden Hill's original shimmer — the setting sun catching glass on the hillside, seen from the ocean — and for gold's true origin, forged long before our Sun and carried here from a distant sun.
