Project Vision

The Herst Coffee Roasters remodel is conceived as a residential sanctuary masquerading as a coffee bar — a space where the ritual of specialty coffee is elevated through material richness and architectural intention.

This brief outlines a curated palette of primary and accent materials that honor the artisanal heritage of the roastery while delivering a hospitality environment of genuine sophistication. Every surface, finish, and fixture has been selected to create a cohesive, moody, and deeply considered interior.

Central to the transformation is the introduction of PINKYS steel doors opening directly to the street — anchoring the façade and inviting the neighborhood into the space with drama and permanence.

"Honed, stone surfaces in dialogue with soft, warm textures — an appeal to luxury rooted in craft."
Design Principle

The goal is not renovation — it is transformation. To create a cultural outpost that feels as though it has always existed here: earned, layered, and completely at home.

Primary Flooring

F-01 · Primary
Cipollino Marble
Large Format · Polished · Italian Origin

Quarried in Tuscany's Carrara region, Cipollino is defined by its dramatic swirling veins of deep green, grey, and white — each slab a unique work of geological art. Large-format installation creates a richly textured, moody interior ground plane that anchors the entire material story.

Interior · Primary Field
F-02 · Accent Floor
Sagano Matcha Verde Marble Mosaic
1×4 Elongated Oval · Honed · Turkish Origin · Staggered Set

Premium Grade Sagano Vibrant Green Matcha Verde Marble in a 1×4 elongated oval mosaic format — honed to a matte, tactile finish. The cool grey-green tones and white veining of each individual tile create a richly patterned field when set in staggered rows, bridging the Cipollino's bold green drama with a quieter, more intricate ground plane in transitional zones.

Accent Floor · Mosaic · Honed

Wall Finishes

W-01 · Primary
Dark Walnut Paneling
American Black Walnut · Book-Matched · Custom Millwork

Dark walnut cabinetry and wall paneling deliver the "moody and intimate" quality that defines the finest hospitality environments — referencing the warm gravitas of historic London gentlemen's clubs. Grain variation is part of the character; consistent finish, natural imperfection.

Wall Primary · Millwork
W-02 · Accent
Fluted Plaster
Hand-Applied · Vertical Flute Profile · Matte

Where walnut yields to lighter register, fluted plaster adds tactile texture while maintaining a sophisticated, quiet atmosphere. The vertical rhythm of the flutes elongates wall panels and creates a refined interplay of light and shadow — particularly effective under warm directional lighting.

Accent Wall · Relief Texture

Service Counter & Millwork

C-01 · Feature Counter
Calacatta Viola Marble
Book-Matched Slab · Honed or Polished Finish · Brass Inlay Detail

The service counter is the spatial centerpiece — the place where the ritual of coffee is performed. Calacatta Viola, with its signature purple-grey veining on a warm white ground, delivers a distinctive and unmistakably curated counter surface. Paired with polished brass logo inlays and custom deep-green millwork below, the counter reads as both workhorse and objet d'art. This material choice signals intent: this is not a typical café.

Seating & Bar Programme

STANDING BAR TABLE SEATING
S-01 · Primary Seating
Standing Bar & Table Programme
Walnut Counter · Leather Bar Stools · Bouclé Chairs · Marble Top

The seating programme is organized around two distinct social modes: a standing bar along the service wall — topped in Calacatta Viola marble with a brass foot rail, upholstered leather bar stools in deep tobacco — and round café tables in dark walnut with mid-century bouclé chairs for longer dwell. Together, they accommodate the full spectrum of the café experience: the quick espresso at the bar and the extended meeting at the table.

Standing Bar · Marble Top Leather Bar Stools Round Tables · Walnut Bouclé Side Chairs
S-02 · Bar Stools
Full-Grain Leather Stools
Full-Grain Leather · Deep Tobacco · Counter Height

Counter-height bar stools with leather-wrapped seats and walnut or blackened steel frames line the standing bar. The leather will patina with use — accruing the character of a well-worn saddle — creating the lived-in quality that distinguishes Herst from a polished café.

Bar Height · Counter Seating
S-03 · Table Chairs
Yellow Bouclé Side Chairs
Wool Blend · Mid-Century Form · Table Height

Yellow bouclé side chairs at round walnut café tables introduce mid-century warmth and a moment of unexpected cheer in an otherwise tonal interior. The textural contrast of bouclé against smooth marble and dark wood is intentional and considered — not decorative pastiche.

Bathroom Material Palette

Design Direction — The Herst bathroom palette is drawn from a curated mood board pairing deep forest green, fluted white marble, rose-bronze fixtures, and stacked ceramic tile — a moody, considered interior that extends the main space's material DNA into the wet areas.
B-01 · Wall Tile
Deep Green Elongated Subway Tile
Vertical Stack · Glossy Glaze · Forest Green

Deep forest green elongated subway tiles in vertical stacked bond — glossy glazed finish that catches and reflects warm light. Applied to wet wall zones and shower enclosures, these tiles reinforce the brand's deep green signature at the most intimate scale.

Shower · Feature Wall
B-02 · Vanity
Fluted White Marble Vanity
Vertical Flute Relief · Honed · White Carrara

A fluted white marble vanity — the same fluted language used on the walls of the main space, here translated into stone. The vertical ribbing catches directional light beautifully, creating rhythm and shadow across what would otherwise be a flat surface. Anchors the bathroom with material weight.

Vanity · Basin Surround
B-03 · Accent
Silver Metallic Mosaic
Small Format Square · Metallic Glaze · Mirror Finish

Small-format silver metallic mosaic tile used as a ceiling inset or niche accent — the reflective surface amplifies light and adds a moment of unexpected shimmer. A subtle luxury detail that elevates the overall finish level.

Ceiling Inset · Niche Accent
B-04 · Paint
Sage Matte Wall Paint
Muted Sage Green · Flat / Eggshell · Non-Wet Zones

A muted, dusty sage green on non-wet wall surfaces — quieter and lighter than the deep forest green tile, this paint tone bridges the dark palette of the main space with the brightness needed in a bathroom. Flat or eggshell finish; moisture-resistant formulation.

Paint · Dry Wall Zones
B-05 · Fixtures
Rose Bronze / Copper-Tone Fixtures
Arched Gooseneck · Warm Rose Bronze · Basin

Arched gooseneck faucets in a warm rose-bronze finish — the fixture choice that bridges the green tile, white marble, and dark walls with a warm metallic note. The rounded arch form echoes the Air 4 Mini Arch door profile, creating a quiet continuity of curved language from façade to interior to bathroom. Specified throughout: basin tap, towel rail, and accessories.

Basin Tap Shower Fitting Towel Rail Rose Bronze Finish
B-06 · Accessory
Rose-Taupe Shelf / Tray
Powder-Coated Steel · Warm Mauve-Taupe · Shelf & Tray

A warm rose-taupe shelf or tray surface — powder-coated steel or lacquered timber — introduces a dusty warmth that softens the contrast between dark green tile and white marble. Used for vanity trays, floating shelves, and accessory surfaces.

Vanity Tray · Floating Shelf
B-07 · Background
Deep Forest Green Panel
Textured Lacquer or Linen-Weave Wallcovering · Dark Green

The primary background surface — a deep forest green in textured lacquer or linen-weave wallcovering — sets the mood of the entire bathroom. This is the same deep green from the main space millwork palette, here used as a full wall treatment to create an enveloping, intimate atmosphere.

Feature Background · Full Wall

Secondary Accents

A-01 · Hardware
Polished Brass
Hardware · Lighting · Counter Inlays

Polished brass appears consistently throughout: door pulls, light fixtures, counter inlays, and shelf hardware. The material bridges warm wood tones and cool stone surfaces, providing cohesion across the palette. Specification includes pendant lighting in the tradition of Achille Castiglioni's "Light Ball" — bold, graphic, mid-century references.

Hardware · Lighting · Inlays
A-02 · Millwork Color
Deep Green Lacquer
Textured Lacquer Finish · Custom Millwork & Paneling

Deep forest green is the signature brand color — applied to textured lacquer panels, millwork below the service counter, and select architectural details. It ties Cipollino's natural green veining back into the designed environment, creating chromatic continuity across stone and crafted surfaces.

Façade Transformation — PINKYS Air 4 Double Mini Arch

AIR 4 · DOUBLE MINI ARCH
Specified · pinkysirondoors.com
PINKYS
Air 4 — Double Mini Arch
Air 4 Series · Double · Mini Arch Top · Street-Facing Outswing

The street-facing façade is the first and most enduring impression Herst makes on the neighborhood. The Air 4 Double Mini Arch — with its signature arched top panels and slim steel sightlines — transforms the entrance from a functional threshold into an architectural statement. Hand-crafted from 12-gauge cold-rolled galvanized steel with 5/8" Low-E dual-pane tempered glass and a polyurethane foam core, the door floods the interior with natural light while the arched silhouette introduces a classical note against the contemporary steel finish. Opening outward to the street, the double configuration creates a grand, welcoming gesture.

Design Intent — The Air 4 Double Mini Arch serves a dual purpose: a meaningful upgrade in energy performance and security, and a defining architectural gesture for the building's street presence. The mini arch top introduces a classical, almost Mediterranean warmth to the steel frame — a counterpoint to the industrial material that echoes the residential sanctuary quality of the interior. When open, the double panels dissolve the boundary between café and street. When closed, the expansive glass creates a lantern effect — warm light projecting outward, drawing passersby in.

Lighting Strategy

Mid-Century Pendants

Spherical brass pendant fixtures — referencing Achille Castiglioni's "Light Ball" lamp — provide warm, graphic punctuation above the service counter and key seating zones. Bold, iconic, unmistakably considered.

Hidden LED Strip Coves

Warm-white LED strips integrated within walnut millwork and ceiling coves create ambient illumination that highlights the natural grain of dark walnut and draws out the pattern within Cipollino marble. Color temperature: 2200–2700K throughout.

Directional Accent Lighting

Recessed directional downlights and adjustable track spots create theatrical vignettes — highlighting the marble service counter, framing seating nooks, and washing dark walnut panels with warm directional light. Atmosphere by intention, not accident.

Lighting Philosophy — All sources spec at 2200–2700K (warm white) to reinforce the residential, intimate quality of the interior. No cold or neutral-white fixtures. Dimming capability throughout. The exterior PINKYS steel doors act as a fifth lighting element — when illuminated from within, the glass grid becomes a beacon.
