Leipzig is a mercantile city in Saxony with a proud history of trade, books and exchanges. Today, the site provides a rather heterogeneous context of socialist apartments and hotel towers, alongside 19th century grand-hotels and late 20th century office blocks. The SAB, the federal development bank of the state, will relocate into a new Leipzig headquarter for 600 staff.

Offices are designed to be open and transparent, creating an efficient yet loose array of stacked and overlapping floor-plates; they will be cooled and heated through the columns by a geothermal system. Efficient shading and insulation, in combination with activated exposed concrete surfaces and decentralised ventilation, will create a simple yet highly sustainable bank of the future and an important new public institution in the centre of Leipzig.
