Who we are

We are architects, engineers, designers and makers, lighting experts specialised in the planning, implementation, and production of light. Our work moves between design and build, combining technical precision with hands on craft.Rooted in Beirut, we have spaces in London, Antwerp, Bologna, Paris, Dubai, Amsterdam, New York, and Berlin. This network allows us to work closely with architects, partners, and clients across different regions and contexts.Since 2004, PSLab has grown into a team of over one hundred specialists who contribute to every stage of our work, from concept and engineering to fabrication and installation.

What we do

We design and build lighting for architecture and the spaces people use every day. Our work spans residential, cultural, commercial, hospitality, and public projects.We develop custom fixtures, adapt existing components, and design integrated lighting systems that respond directly to context, material, scale, and use. Every project results in a specific solution that supports how a space functions, feels, and is experienced.Our archive documents the fixtures, systems, tests, and learnings that emerge from this work. It is a practical resource we draw on to refine existing ideas, develop new ones, and ensure each project benefits from the knowledge built across many years of making light.View our Archive [↗]

How we work

We approach each project from a blank slate. There is no catalogue; every light is designed and built specifically for its space.Design, engineering, and production operate as one. We move directly between drawing, testing, prototyping, fabrication, and installation, keeping the process efficient and grounded in real conditions.We stay closely involved on site, coordinating with architects, clients, and makers to ensure each detail performs as intended. This direct collaboration allows us to respond to constraints, adjust quickly, and deliver solutions that work in practice.
