medioestudio reorganized a fragmented 55 m² apartment along Madrid Río Park by making its terrace disappear into the living room, not by building toward it. The original layout turned its back on the park despite sitting right alongside it, splitting the plan into compartments that blocked both light and view. The renovation resolves around a single bedroom and one large sliding window, collapsing the distance between inside and the landscape outside.
A generous central space now absorbs the kitchen, dining area, and living room into one continuous zone, replacing the fragmented plan that isolated each function in this Madrid Río Park apartment. Rather than treating openness as a stylistic choice, medioestudio used it to solve the apartment’s core problem: a 55 m² (592 sq ft) footprint that couldn’t afford wasted circulation. The kitchen, once boxed off, now reads as part of the same gesture that opens toward the terrace.
The terrace becomes a room itself once the large sliding window opens the central space directly onto it, aided by a floor level flush with the interior. That continuity does more than enlarge the apartment visually — it makes the Madrid apartment renovation‘s natural light and park views functional parts of daily life rather than incidental backdrop, a strategy Teleno Studio pursued from the opposite direction in House in Penumbra, where light was rationed rather than maximized.
The entrance was redefined as a working threshold, built-in storage absorbing what used to be dead space at the apartment’s edge. Circulation improves specifically because the entry stops being just a passage and starts pulling its weight, storing what the compact plan has no room to spare elsewhere. In a 55 square meter apartment (592 sq ft), every transitional space either earns its function or gets eliminated.
Wet areas were reconfigured for flexibility rather than expanded, since the compact footprint ruled out adding square meters to the bathroom in this compact Madrid apartment. The washbasin moved to a semi-open space that catches natural light and allows simultaneous use, while more private functions stayed adjacent to the existing service core. Keeping interventions close to the original plumbing kept the renovation efficient rather than invasive.
Color functions as an architectural tool here, not decoration — a warm, restrained palette of contrasting tones paired with the natural texture of wood defines zones without breaking the plan’s spatial continuity. Where walls might have divided the open space back into rooms, color does that job invisibly, letting Casa Río stay legible as one flowing area rather than a corridor of ambiguous zones. moca estudio reached a related conclusion in Casa GNR, using peripheral materials to define space in another compact Madrid apartment without adding partitions.
A ceramic lattice moves indoors in this Casa Río renovation, a material typically reserved for exterior architecture reassigned to establish continuous dialogue between the interior and the terrace. The lattice blurs the boundary between inside and outside more literally than the sliding window does, filtering rather than framing the relationship between the two.
The renovation’s real achievement is subtraction, not addition — eliminating unnecessary circulation space and redefining the relationships between rooms without adding a single square meter to the original 55 m² (592 sq ft) footprint. Casa Río proves that a compartmentalized apartment’s problem is rarely size; it’s usually the walls pretending the rooms need to stay separate. Whether every fragmented Madrid apartment can survive that same subtraction, or whether some layouts are broken beyond what removing walls can fix, is the harder question this project leaves open.
