The LL331 Lobby in Barcelona is conceived as a contemporary corporate threshold that merges technology, material warmth and urban permeability. The design seeks to express the identity of a high-performance office building through a clear, sculptural composition of elements: a monolithic reception desk, luminous ceiling lines and cylindrical structural volumes. The lobby acts as a calibrated filter between city and workplace, orchestrating flows of people with an architecture that communicates precision, innovation and openness.
The spatial narrative is built around three layers: the urban front with its transparent revolving doors, the security and access-control core, and the reception and waiting areas framed by a green backdrop. These layers are visually unified by a continuous timber slatted ceiling and an expressive light sculpture that traces a dynamic trajectory above the central axis, evoking data flows or sound waves.
The layout prioritizes efficient circulation and intuitive wayfinding. A fully glazed entrance zone maximizes visual continuity with the street, inviting users into a generous vestibule before transitioning into the controlled lobby interior. The cylindrical cores operate as both structural and spatial anchors, subtly guiding visitor movement around them and framing direct lines of sight toward the reception desk.
The access-control gates are aligned orthogonally with the main facade, forming a clear, linear threshold that separates public and semi-public domains. Their positioning in front of the reception ensures supervision while preserving a sense of openness. Secondary waiting and informal meeting pockets are located to the sides, where circulation slows down and acoustic comfort increases.
The material palette combines tactile natural finishes with refined metallic and glass surfaces to balance warmth and corporate sophistication. The continuous timber slat ceiling introduces a domestic scale overhead, improving acoustics and visually elongating the space. Its linear geometry is echoed in the integrated lighting tracks, reinforcing depth and direction.
The reception desk is executed in a light grey stone with a faceted geometry, producing a crystalline, sculptural presence. Underlit plinths and recessed base details create a floating effect that reduces the perceived mass of the element. Brushed stainless steel in the access gates and column claddings adds a technical, precise character, while large-format porcelain or stone flooring ensures durability and easy maintenance.
Lighting plays a central role in articulating the brand identity of LL331. A custom, sinuous light sculpture suspended above the reception axis becomes the visual signature of the lobby, translating the company’s dynamism into a three-dimensional luminous gesture. Integrated linear luminaires in the ceiling slats and column crowns provide uniform ambient light without visual clutter.
Vertical surfaces are carefully illuminated to emphasize depth: the green wall behind the desk receives grazing light that accentuates texture, while the black glossy volumes at the perimeter reflect and multiply light, amplifying the perceived space. The LL331 logotype appears as a backlit element embedded within the green wall, clearly legible from the entrance and reinforcing orientation.
Sustainability is addressed through both visible and invisible strategies. The vertical green wall behind the reception contributes to improved indoor air quality, microclimatic regulation and acoustic absorption, while also introducing a biophilic component that softens the technological character of the lobby. Plant species are selected for low maintenance and adaptability to interior conditions.
Energy-efficient LED lighting, presence and daylight sensors reduce consumption by adapting levels to real occupancy and natural light. The high degree of facade transparency optimizes daylight penetration, decreasing reliance on artificial illumination during daytime. Durable, low-emission materials are specified for floors, wall claddings and sealants, supporting a healthy indoor environment and reducing life-cycle impacts. The overall design is conceived to age gracefully, minimizing the need for future replacements and associated resource use.
