EXCLUSIVITY BONAPARTE - Located on rue de Billancourt, just steps from the Passages, Saint François d’Assise School, Léon Blum Square, and all amenities, a duplex of 76.82m2 Carrez (120.61m2 on the ground), within a characterful co-ownership dating from the 1910s, on the 4th and top floor without elevator. The apartment has been completely renovated by an architect, offering atypical volumes and a unique charm under the roofs with an unobstructed view of Boulogne.

The entrance leads to a first level perfectly optimized.
On one side, the living room of nearly 36m2, bathed in light thanks to its east exposure and unobstructed view. The space is perfectly designed with a kitchen-dining area and a lounge area. The modern spirit offered by the open kitchen, the custom bookshelf, and the wrought iron staircase perfectly match the charm of the old apartment.

On the other side of this level, there is the children’s sleeping area including two bedrooms of 13.06 m2 and 6.40 m2, the latter can easily serve as a children’s room or an office.
A bathroom of 3.15 m2 completes this level.

From the living room, the wrought iron staircase leads to the upper floor hosting a master suite under the roofs, hidden from view.
Here, the floor space is significantly larger than the Carrez surface, offering a real feeling of cocooning under the roofs. Thanks to the mansard volumes, many custom storage spaces have been created. An adjoining bathroom completes this floor, forming an intimate and warm space.

The entire apartment benefits from a complete quality renovation, subtly blending the charm of the old (parquet, volumes under the attics) and contemporary features.
Unique atmosphere between family apartment and house under the roofs.

Property subject to co-ownership regime.
