Особняк Гутхейля, Art Nouveau manor estate in Khamovniki District, Russia

The Gutheil manor is a symmetrical Art Nouveau house built in 1902–1903 by architect William Walcot for the Moscow Trade and Construction Company. Its smooth walls are clad in light pinkish-lilac glazed tiles, and the semicircular windows and entrance are framed by panels with pale rocaille stucco. A glass canopy above the door echoes French Art Nouveau.

The plot once belonged to a service yard of Prince I. A. Gagarin's estate, later bought around 1816 by brigadier N. I. Mukhanov. In 1899 the Moscow Trade and Construction Company of Ya. A. Rekk divided the land into three plots; William Walcot's project was built in 1902–1903. The house was soon sold to Karl Gutheil, head of the music publishing firm A. Gutheil from 1882, which issued most of Rachmaninoff's works. Since 1958 it has housed the Moroccan embassy.

The house is named after Karl Gutheil, who took over the music publishing firm A. Gutheil founded by his father in 1882 and made it one of the largest sheet-music publishers in the Russian Empire. It issued most of Rachmaninoff's works and compositions by Balakirev, Arensky and Grechaninov, and in 1885 acquired rights to a large part of the operas of Glinka, Dargomyzhsky, Serov and Verstovsky. Since 1958 the building has housed the Embassy of Morocco.

The mansion at Prechistensky Pereulok 8 houses the Moroccan embassy, so only the street facade is accessible. The pink-lilac glazed tiles, stucco panels and the glass canopy over the entrance are best seen from the opposite side of the lane. The restored wrought-iron fence reproduces Walcot's original wavy scrollwork.

The building's central volume recalls the rizalit of the Derozhinskaya mansion built by Fyodor Schechtel a year earlier, yet art historian Maria Nashchokina notes that the Gutheil house found no imitators among Moscow Art Nouveau architects. The original low wrought-iron gate with Walcot's wave-like scrolls was lost and rebuilt in a neoclassical style; the 2011 restoration recreated it in its first form.
