Trade terms for professionals and design studios

Indian architecture has always moved through covered open air — verandahs, colonnades, shaded courts where inside and outside negotiate. Osso & Bottone speaks that language: the first Mutina collection created expressly for exterior spaces, with R11 slip resistance, barefoot class C and 0.15% water absorption, so a walkway stays safe through the monsoon and elegant through the dry season.

Designed by Ronan Bouroullec in 2024, the four modules are sculpted rather than printed: Osso narrows at its waist like a bone, Bottone carries circular edge cuts that close into perfect rings across the mandatory 4 mm joint — the pattern literally appears in the grout. Unglazed porcelain, full-body coloured with mixed earths in five shades (Sabbia, Grigio, Rosso, Blu, Verde), 10 mm thick, with stain class 5 and class A chemical resistance for floors that host chai, turmeric and everything in between.

Plan it across the connective tissue of a campus or hotel — entrance courts, corridor loggias, café terraces — and let the same surface continue into reception. Technical sheet and certificates can be downloaded from this page.

FAQ

Will the surface stay safe during monsoon months?
The declared slip values are built for wet use: R11 on the ramp test, barefoot class C, DCOF 0.66 and a wet pendulum value of 45. Combined with 0.15% water absorption, that is a floor designed to be rained on, not just to survive it.
Why are the edges of the tiles cut away?
Because the ornament lives in the joints: Ronan Bouroullec sculpted the rectangles so their voids — a bone-like waist on Osso, semicircles on Bottone — compose patterns once the pieces are laid with a 4 mm joint, mandatory on Bottone S and L.
Does strong sun affect the five colours?
The shades are not painted on: they are mixed coloured earths running through the entire 10 mm body of unglazed porcelain. Declared resistance to thermal shock and chemicals class A complete the picture for exposed terraces and courts.
Is this collection suitable for interiors as well?
Yes — it was born outdoors but finished for both worlds. In hotels and offices the same colour often runs from the shaded walkway into reception, so the building reads as one continuous ground.
How is maintenance handled on high-traffic walkways?
Stain resistance is class 5, the highest rating, and routine care is simply a porcelain detergent diluted in water. Finish samples can be requested; their cost is fully credited at order confirmation.

From verandah to reception: laying out Osso & Bottone

Five steps to bring Mutina's outdoor-first porcelain into Indian courts, colonnades and the rooms they lead to.

Trace the covered-open route
Mark every space that lives half outside — entrance court, loggia, terrace café — and treat them as one continuous floor rather than separate finishes.
Match shape to pace
Bottone's ringed joints animate places where people pause; Osso's quiet taper suits long circulation. One shape per stretch keeps the rhythm legible.
Hold the 4 mm joint
Specify it as a fixed dimension — mandatory on Bottone S and L — with cement grout for exposed areas and epoxy reserved for interiors.
Test grout colour under your own sky
Tropical light is unforgiving: compare tone-on-tone against contrast on a real panel at noon and at dusk before deciding.
Quantify by shape, blend by box
Each format covers differently per square metre; order per shape and blend pieces from several boxes during laying to spread the V3 earth-shade variation.
