Ideally located between Montmartre Hill and the Batignolles district, in a stunning 1930s Art Deco building designed by architect André Contenay, this rare 320 sqm (3,444 sq. ft.) mixed-use space (residential and commercial) captivates with its originality and exceptional volumes. The main living area, a 194 sqm (2,088 sq. ft.) family loft (181 sqm / approx. 1,947 sq. ft. under Carrez Law), opens immediately upon entry onto an impressive glass roof that floods the entire space with natural light. The expansive 52 sqm (560 sq. ft.) living room, extended by a contemporary kitchen at the heart of the apartment, creates a truly convivial space. The 31 sqm (334 sq. ft.) master suite includes its own bathroom and a custom walk-in closet. Two additional bedrooms share a modern bathroom. A laundry room and guest toilets complete this level. A private period freight elevator serves all three floors, adding unique character to this atypical property. On the ground floor, a spacious fourth bedroom—adaptable as an office, TV lounge, or reception area—features its own shower room and toilet, offering both comfort and flexible usage. The commercial section, currently operated as a classified 3-star furnished tourist rental, has a separate entrance. It includes three bedrooms and a living room with an open kitchen, as well as two shower rooms—providing attractive rental profitability. Finally, on the top floor, a soundproofed, air-conditioned private concert room—adaptable for other uses—perfectly completes this unique property. This property will appeal to lovers of distinctive architecture and inspiring spaces, seeking peace, light, and a prime location just steps from shops, schools, and public transport.
