From the Architect: "In the heart of Rome’s Trastevere district, Studio Tamat has breathed new life into a hidden Liberty-style gem tucked away in the courtyard of a late 19th-century building along Viale di Trastevere. Once the caretaker’s house for the old train station (or a neighborhood doctor’s office, depending on who you ask) this forgotten villino has been reimagined as a refined urban hideaway for two.

"Spread across three compact layered floors occupying 861 square feet and culminating in a lush, green terrace, the project began by carefully preserving the home’s most distinctive elements. Restoring the front veranda with its delicate cathedral glass in soft greens, pinks, and yellows called for a mix of craft and technical precision. The original rhythm and hues were respected, while the frame was rebuilt in steel and solar-control glass. By removing the old French door that once divided it from the house, the veranda now flows into the interior, extending the living space and bathing it in natural light that shifts in tone throughout the day. Inside, the intervention reconfigured the layout, previously fragmented by a tight spiral staircase, and on the perception of the spaces. The redesign is radical in gesture but sensitive in execution: by moving the kitchenette beside the veranda, space is opened up for a striking alternating-tread staircase in chestnut wood. Its first step, clad in Verde Alpi marble, becomes the sculptural base of a custom bookshelf built underneath. Nearby, a mirrored chestnut storage unit conceals the laundry and enhances the sense of openness.

"The living room gains new depth, framed by a soaring double-height window that looks out onto surrounding gardens, in quiet harmony with Munari’s iconic Falkland pendant lamps. The custom kitchen, liberated from overhead cabinetry, is defined by a linear base topped in Verde Alpi marble and shaded drawers that fade from black to terra-cotta, echoing the preserved original terra-cotta floors. A deep blue volume organizes the ground floor’s services: fridge and pantry on one side, a discreet powder room on the other.

"This bold block of color continues upward, passing through the mezzanine and defining the main bathroom on the top floor, where Nouveau furnishings by Ex.t meet the textured surfaces of Patricia Urquiola’s Mater tiles for Mutina and fixtures by Formafantasma for Quadro Design. To bring in light and create a sense of airiness, the mezzanine has been partially opened, introducing a double-height void. Glass floor panels offer glimpses between levels, while mirrored panels below bounce reflections upward, visually expanding the space and enhancing the blue volume. The remaining floors are finished in Foret parquet by Oscar Ono Paris, designed by Raphael Navot—preassembled oak slats with visible end grain, a nod to the pebble streets of 19th-century Paris and ancient Rome. A custom bed with drawer base and integrated headboard echoes the kitchen’s color gradient, creating visual continuity between the levels.

"A second spiral staircase in raw iron with cherry wood treads connects the sleeping area to the upper level, serving as a sculptural focal point for the studio space. A glass partition, echoing the veranda’s rhythm with alternating clear and ribbed panels, elegantly screens the bathroom: the door doubles as a backdrop for the shower, while a Verde Alpi marble sink slices through the glass, becoming a shared counter surface. Outside, the terrace features compacted stone paving in two shades of green, blending into the surrounding vegetation and reflecting the palette.

"Discreetly nestled in one of Rome’s most characterful neighborhoods, this intervention captures the quiet charm of Trastevere. Just like the district itself, where modest facades often hide unexpected treasures, this project reveals the latent beauty of a neglected house. Merging memory with material, and history with contemporary sensibility, Studio Tamat has created a deeply rooted, yet strikingly modern urban refuge."
