Permanently Unique Group has expanded its modern Greek dining concept to London with the opening of Fenix Mayfair, featuring interiors designed by Studio WYZE. Spanning 4,500 square feet within a 1920s Portland stone building, the venue translates Cycladic design into an interconnected sequence of light-filled dining and intimate bar spaces [1].
Where is Fenix Mayfair located and what is its background?
Fenix Mayfair is housed inside a 1920s Portland stone heritage building in London's Mayfair district, marking the concept's official capital debut [1]. The modern Greek restaurant brand originally launched in Manchester in 2023 under hospitality operator Permanently Unique Group [1]. As reported by Hospitality Design, the London expansion occupies 4,500 square feet of floor space tailored to create a Greek island atmosphere [1].

How did Studio WYZE approach the architectural layout?
Studio WYZE designed the floor plan to respond directly to the 1920s building's structural footprint by maximizing incoming natural daylight [1]. Sculptural plaster arches guide patrons across interconnected zones rather than divided rooms [1]. This spatial sequence transitions guests from an airy, sunlit dining area into a darker, intimate evening bar [1].
According to Hospitality Design, the studio balanced Mayfair's quiet luxury aesthetic with Mediterranean warmth by applying a restrained palette of neutral tones and natural materials [1]. Studio WYZE cofounder and principal Christina Arbenz noted that the design explores rhythm and restraint by letting the historic architecture shape the interior layout [1].
| Design Feature | Material or Specification | Functional Area |
|---|---|---|
| Backlit Feature Wall | Greek decorative bricks with dynamic color-shifting illumination | Main Dining Area |
| Architectural Partitions | Curved sculptural plaster arches and decorative breeze blocks | Circulation & Dining |
| Flooring Surfaces | Italian parquet and terrazzo flooring | Dining Room & Bar |
| Bar Counter Front | Bronze feather-front counter | Bar |
| Bar Feature Wall | Lava-stone back bar and fluted rammed earth panels | Bar |
| Wall Treatments | Dual plaster finishes evoking Mykonos textures | Throughout Venue |

What lighting strategy was implemented inside the venue?
Studio WYZE partnered with specialist firm INTO Lighting to install a dynamic lighting system that shifts throughout service hours [1]. Where natural exterior light fades, a feature wall made from Greek decorative bricks provides color-shifting illumination that mirrors the sun's changing tones [1]. This dynamic scheme ensures the dining environment transitions smoothly from daytime lunch covers to late-night lounge seating [1].
What materials define the dining and bar spaces?
Tactile finishes and raw textures define the venue, including dual plaster wall treatments designed to mirror the physical textures of Mykonos [1]. The bar area combines terrazzo flooring, Italian parquet, fluted rammed earth panels, and a back bar built from lava stone [1]. The centerpiece bar counter features a bespoke bronze feather-front design, set alongside custom furnishings and sculptural decorative breeze blocks [1].
Hospitality Design highlighted that the design goal was to recreate a relaxed Greek island gathering in London without imposing rigid or formal hospitality constraints [1].
