The Jahu apartment building is located in Kalamaja, in a melting point of different eras. The building is situated right between two areas, one with well preserved historical wooden houses and the other with contemporary architecture.

Taking the plot into account, a 5-storey building with 37 apartments was designed. With a footprint of 840 m2, the building is situated in accordance with existing valuable trees and at the same time creates a south-facing garden with lilacs, apple- and cherry trees. This kind of gardens are characteristic for the historic Kalamaja courtyards. The flats on the ground floor have terraces with small gardens in front of them to separate them from public areas and give more privacy to the inhabitants.

Starting from the 2nd floor, apartments facing north have a view to the sea and flats to west have a nice overview of Kalamaja. From the 3rd floor all the apartments to south are looking to the medieval old town of Tallinn. Flats to the east see the modern face of the city with its urban courtyards.
