Today Willen House is a student residence.  Its website says that, "Willen House is located on Bath Street EC1 in the heart of cosmopolitan Islington, and is ideally situated for access to all of City University's buildings. The residence's interior was extensively modernised in 2007, and the unique 'Bauhaus' exterior dates back to the 1940s."

The name comes from the original occupant, the Willen Key Company that was founded in 1903 by James Walker.   Apparently the reason for Willen was that in those days Willenhall in Staffordshire was the home of lock and key making.  The company's original premises were in Battersea but in 1923 they moved to a larger building in Bath Street off City Road.  During WWII their Bath Street building was destroyed and the company moved its operations to Willenhall.  After the war they returned to Bath Street occupying this grand new building.

Today, Willen House says that it has, "... accommodation spread over six floors, (and) offers postgraduate students a friendly and supportive environment for living and studying.  Each room is a self-contained studio study room with its own ensuite bathroom and kitchenette area.  The studio rooms are competitively priced according to the different sizes and position within the building, streetside or non-streetside. All rooms have windows."
