Charlemagne Croco
On a quiet street in Luxembourg City, a corner house from 1957, later converted into a day care centre, had lost its domestic coherence. Thick fire doors, sealed thresholds, and subdivided rooms turned the interior into a sequence of controlled compartments. Floors were interrupted, and the garden, buried beneath concrete and rubber tiles, was cut off from the house.

The project restores the house through a precise reworking of its architectural elements. Toward the street, the intervention is restrained: façades are repaired, window frames refined, and interior joinery adjusted to recover depth and proportion. Toward the garden, the approach shifts: The terrace and winter garden are removed, along with part of the rear slab, opening the section.
A cubic extension is inserted, clear in geometry. Inside, the floor unfolds as three stepped levels, defined by subtle shifts in height, material junctions, and built-in elements. The sequence from living room to kitchen to garden level becomes a continuous gradient, where steps act as thresholds, integrated seating, and storage.

 Sloped ceilings integrate structure and services within a continuous envelope. Fixed elements—kitchen, storage, sanitary core—are compacted along the edges, freeing the central space. At the rear, six sliding glass panels, each 4.5 metres high, transform the façade into a mobile plane, extending the interior toward the garden, or vice versa.
