Arsenit

Arsenit is an architecture and design studio based in Tallinn, Estonia, founded by Arseni Timofejev. Its work moves between buildings and products, with a close interest in construction detailing and in how a small structure can be made precise, repeatable and gentle on its site.

The clearest example is Piil, a full-scale prototype of an elevated retreat built in 2023 in an Estonian pine forest near the Jägala river: one leg holds the stair, the services and a store, the accommodation is prefabricated in modules that a crane bolts together, and the envelope is a rainscreen of thermally modified pine that weathers to silver-grey without oiling. The prototype later became a modular product sold through piil.ee. Other projects include the Little Prince Kindergarten, an extension to an 1899 villa, and the Rae Rist school campus.
