I HOUSE
The present work is a rehabilitation and an almost complete reconfiguration of an existing Florentine-Moorish style house — a style often found in interwar Bucharest in houses and apartment buildings known for a high quality of architectural expression. Its most frequent elements include calcio vecchio plaster, twisted spindle columns with floral capitals accompanying arches or windows, arched, broken, or flattened openings, consoles with buttresses, and prominent window sills.
The challenge of the project was to reintegrate the original architecture with its specific details and materials into a building that is completely reconfigured on the inside and partially on the outside — a modern structure in which technology and functionality support spatiality.

The process was long, beginning in 2019, and involved three building permits: two for the main body and one for the gazebo extension and walkway construction. The main volume was extended vertically, the arched windows lost their parapets, and the street-facing window was reconfigured to receive more morning light from the east.
The spatial reconfiguration was necessary to enable a functional reorganization and to bring scale and light into the interior. Through this, we created two major vertical spaces — the orangery and the dining room — which became the most representative living areas of the house, complemented by the living room and the exterior pavilion.
The interior design is limited to a few materials characteristic of the period in which the house was built — mainly mosaics, parquet, metal, stone, and decorative plasters — with areas of apparent sandblasted concrete. Externally, mosaic and washed mosaic finishes were used. The stamped lime plaster was restored on all façades and inside the orangery.
The joinery was custom-designed for the location using steel profiles with thermal breaks. The furniture is custommade and uses walnut veneer, recomposed veneer, solid walnut wood, marble and marble mosaic. The terazzo poured over the underfloor heating followed two different recipes for the interior and for the exterior and greenhouse.
