Berezovy Domik, Architectural landmark in Gatchina Palace Park, Russia.

Berezovy Domik is a rectangular wooden pavilion in Gatchina Palace Park whose exterior walls are designed to resemble stacked birch logs. The interior features elegant plasterwork, painted ceilings, and decorative elements in the neoclassical style.

The Birch House dates from the 1780s; Vasily Brenna, Nikolai Lvov and François Viollet are named as possible authors. The Mask portal in Pudost limestone was built by Brenna in 1795–1797 and survived the war. The Birch House was destroyed during the occupation of Gatchina and rebuilt in 1975 to a design by architect A. A. Kedrinsky.

The name "Berezovy Domik" refers to the birch logs used on the facade, while the stone portal is called "Maska" (Mask) because it hides the pavilion behind it. Such surprise pavilions were used for rest by small groups walking in the park. The interior's mirrors and facing windows make the roughly 25 square metre hall appear larger.

The building is accessible through guided tours offered by the Gatchina Museum-Preserve, which cover several historical structures on the palace grounds. Visitors should prepare for extended walking, especially during wet weather, and comfortable footwear is recommended.

The building feigns a simple wooden hut from the outside while concealing a refined interior space with skillfully painted ceilings inside. This interplay between outward appearance and inner elegance makes the structure a visual surprise.
