SLAB GALLERY

Discover nature's masterpieces

In SLAB Gallery we showcase the very best nature has to offer. Our team travels the world to personally select every slab and ensure that only the most refined pieces make it into the collection.

Selected for spectacular veining, distinctive character and exceptional quality, these slabs turn accent walls, bars, reception desks or tables into compositions with real visual impact. The choice is personal, so we bring you into the process. You can view the materials we discover live, via video call or detailed images, so you can choose the slabs that respond perfectly to your project’s vision, piece by piece.

Applications

Natural stone washbasins, made to order for retail spaces

Every piece begins with the architecture of the space it will inhabit. We analyse the proportions, the routes, the materials, the points of visibility and the way the object will be used. The shape can be curved, geometric, massive, suspended, minimalist or entirely atypical. Dimensions, finishes, edges, cut-outs and fixing systems are defined individually for each project. The result is not a superficially personalised standard product, but an object created from scratch for a single space.

La Mița Biciclista, a cultural landmark reactivated in Bucharest

La Mița Biciclista reopens its doors as a cultural establishment, preserving the memory of the house and translating it through light, materiality, scenography and a direct relationship with the city. Built in 1908, the house combines the Beaux-Arts language with Art Nouveau influences, and the contemporary intervention reactivates its social and cultural character.

DentPost, precision, calm and modernity

DentPost welcomes its patients in a formula that preserves the rigour of a medical space and translates it through light, proportion, tactility and an atmosphere built around a sense of safety. In place of an impersonal clinical expression, the intervention proposes natural surfaces, calm tones and precise details that ease the tension associated with a visit to the dentist.

BOB Coffee Promenada, a meeting place in the flow of the city

BOB Coffee opens towards the flow of Promenada Mall like an urban lounge, without isolating itself from the energy of the public space, yet offering a slower rhythm built around coffee. Located on level 1, the café works simultaneously as a meeting place, a workspace and a pause point in the daily route through the shopping centre.

Casa Icoanei, interwar heritage reconfigured for the present

The house recovers its Florentine-Moorish character through the restoration of the façades and the original details, reinterpreted in a contemporary, luminous and rigorously proportioned formula. The main volume is extended vertically, and the openings are recalibrated to bring the morning light inside and to connect the spaces of the house more clearly.

Panoramic, a reinvented symbol of contemporary Brașov

Panoramic reopens its doors in a form that preserves the building's modernist memory and translates it through light, transparency, materiality and a direct relationship with the landscape. The original building dates from the 1970s, and the contemporary intervention preserves the scale, proportions and structural logic of the modernist landmark.

Material performance

A durable material, processed to keep its appearance and integrity over time.

The material keeps its shade and intensity, even in spaces constantly exposed to light.

Can be used for vertical cladding in bathrooms, kitchens, façades, fences and plinths.

The material can be used in bathrooms and kitchens, with the right installation and treatment system.

You can view and choose every piece individually, in the showroom or remotely, via video call and detailed images.

Every piece can be cut and adjusted in our workshop to fit correctly into the final space.

Colour, texture and natural variation differ from piece to piece.

Large-format slabs allow visual continuity and let the stone's natural pattern flow across extended surfaces.

Specialised transport through our own fleet or partner network.

We can provide installation and maintenance services with a specialised team.

SLAB: from material to project

SLAB Gallery brings together large-format slabs, selected for their veining, colour and one-of-a-kind character. Every slab is a unique piece, a mineral canvas formed over millions of years and ready to become architecture.

Sergiu Constantinescu-Brădescu
SLAB Gallery was born from a desire to create a space dedicated to architects and designers, a place where natural stone could be discovered without haste, at true scale and in all its complexity.

I wanted a living library of materials, not a conventional showroom. A space where you can choose not just a type of stone, but the exact slab that's right for a project, for its veining, colour and one-of-a-kind character.

Here, ideas can begin directly with the material, and our team can carry them forward, from selection and design through to final execution.

Mariana Constantinescu-Brădescu
We created SLAB Gallery as an art gallery at architectural scale: every slab is a unique work, sculpted by nature over millions of years. In our flagship store in Bucharest, architects and designers can see the material at its true size, touch its surface and closely observe the veining, texture and every detail that can't be fully understood from a simple sample. The experience continues online too, through Slab Inventory, where they have access to the real stock available directly at the quarry and can choose exactly the slab they want, with the precise pattern, tones and particularities of that piece, and no other. The latest innovation in our portfolio, an ultra-thin slab of just 0,7 mm instead of the classic 2 cm version, radically changes the rules of the game. It reduces the material's limitations, opens up new possibilities for application and completely transforms the way we will design and work together from now on.
