History
Faubourg 21 is an intimate hotel occupying two historic townhouses on Avenue Marnix in central Brussels, restored by ORIGIN Architecture & Engineering after four years of meticulous work. The two mansions date to the mid-19th-century urbanisation of the city's faubourgs following the dismantling of Brussels' second ring wall: the house at No. 22 was built around 1850 in a neoclassical style, while the mansion at No. 21 was rebuilt in 1907 and is classified in its entirety as a protected historic monument.
Belgian heritage artisans painstakingly refurbished the interiors: mouldings, marble, stretched-canvas walls and hand-repainted faience. Maison Sarah Lavoine dressed the rooms. Reopened as Faubourg 21 in 2025, a member of The Leading Hotels of the World, the property offers 16 rooms and 4 suites.
