Inside Casa en Penumbra: The Madrid Apartment That Turns Shadow Into Luxury
Teleno Studio has reimagined 56 square metres in a 19th-century Madrid building around a single oak volume, proving that small-footprint city living can feel quietly opulent. From Paris to Berlin to New York, it is a masterclass in olive-toned, low-light glamour.

There is a particular kind of luxury that has nothing to do with square metreage. Casa en Penumbra, a 56-square-metre apartment in central Madrid, makes the case beautifully. Renovated by Teleno Studio inside a 19th-century building, it replaces a chopped-up floor plan with one continuous living space, organised around a compact oak volume that does the quiet, clever work of holding the home together.
That core contains the bedroom and bathroom, concentrating the services into a single architectural gesture and freeing the perimeter for kitchen, dining and living. The result is a home that feels generous despite its modest footprint, and one that any city dweller eyeing a smaller second home will recognise instantly.
A strategy of shadow, not sunlight
Most renovations chase daylight. Teleno Studio did the opposite. Rather than maximising the Madrid sun, the studio built a strategy of controlled illumination, layering linen curtains and olive-toned textiles to filter the city’s intense exterior light. The effect is a calibrated penumbra throughout the apartment, where shadow becomes an active design tool rather than something to be banished.
It is a confident approach to interiors, and a surprisingly practical one for apartment living. Soft, managed light flatters materials, softens hard edges and makes a compact plan feel layered and atmospheric instead of exposed. The palette does the rest, with deep olive greens, dark woods and warm metallics setting a mood that reads as expensive without ever shouting.
The case for olive, oak and Emperador
If there is a single reason this apartment lingers in the memory, it is the palette. Casa en Penumbra is built almost entirely from greens, browns and warm darks, a tonal world of olive walls, oak joinery, dark stained timber and the deep, veined drama of Emperador marble. Nothing here is bright or primary. The colour does its work in the mid-tones and the shadows, which is precisely why it feels so expensive.
Olive is the hero, it is soft enough to recede into the background yet rich enough to feel intentional, and it flatters skin, brass, glass and greenery in equal measure. Against it, the warm honeyed wood and the cocoa-toned marble read almost like neutrals, grounding the scheme so that the eye travels rather than snags.
The genius is in the discipline. By keeping the whole apartment within one narrow tonal band, Teleno Studio lets texture and finish carry the contrast instead of colour. Matte plaster sits beside satin lacquer, rough stone beside polished metal, velvet beside glass. It is a lesson in restraint that any reader can borrow. Pick a tone you love, commit to it across walls, joinery and soft furnishings, and let the materials supply the variety.
Every surface here is chosen to play with that low light. Satin finishes, dark woods and reflective elements amplify the subtlest shifts in brightness, while floor-to-ceiling mirrors set perpendicular to the windows pull visual depth across the room and distribute soft gradients of light from one zone to the next. Lacquered pieces and glazed ceramics gain presence through controlled reflection rather than colour.
It is exactly the sort of material intelligence that translates to any city apartment, where outlook is often limited and natural light comes at a premium. The lesson is simple and worth stealing. Lean into tone and texture, let mirrors and sheen do the spatial work, and a small room starts to feel like a considered retreat.
A kitchen that wants company
The kitchen is folded straight into the main living space as a dark wood volume, punctuated by an opening in rich Emperador marble. It is designed for social life rather than hidden away, encouraging the shared rituals of cooking and gathering. Behind the sofa, a stone element carries storage while moonlighting as an informal bar, knitting the living, cooking and dining zones into one fluid scene.
This is open-plan living done with restraint and polish, and it is the part of the apartment that city buyers everywhere will likely covet most. In a compact pied-a-terre, where space is precious and entertaining is often the point, a kitchen that doubles as a backdrop for a good evening is worth its weight in marble.
The oak core and a more private world
Step inside the oak volume and the mood shifts. The bedroom and en-suite bathroom form an introspective domain, with a large sliding door mediating the transition from open social space to something more enclosed and subdued. Light becomes increasingly indirect, deepening the contrast between the collective and private halves of the home.
The bathroom is treated as the most intimate room of all. A red travertine sink is set within a mirrored surface to play up depth and reflection, while metallic and polished finishes respond to humidity and changing light. It is a small space designed to be felt as much as seen, which is rather the whole point of Casa en Penumbra.
A blueprint for the world’s design cities
By combining tight spatial planning, a disciplined material palette and genuinely clever light control, Teleno Studio has shown how shadow can operate as a primary architectural device, shaping both perception and everyday domestic life. For a generation of urban buyers downsizing, dual-keying between cities or simply choosing character over square footage, it is a quietly radical blueprint, and one that travels far beyond Madrid.
The principles hold in any of the world’s great design capitals. Picture them in a Haussmann apartment in Paris, where tall windows and period mouldings would frame an olive scheme beautifully. Or in a converted Altbau in Berlin, where the high ceilings and raw bones reward exactly this kind of tonal, textural confidence. In New York, the same approach would transform a compact Manhattan one-bedroom, trading the relentless pursuit of light for atmosphere and depth.
The FLUXX takeaways are universal. Choose a tonal, light-absorbing palette over magnolia. Concentrate the services so the living space can breathe. Let mirrors, marble and a single sculptural light do the heavy lifting. Whether the address is in Madrid, Paris, Berlin, New York or London, the message is the same. Small, in the right hands, has rarely looked so luxurious.
