This is a hotel sort of near Euston station but I have no clue what it's called or who the architects were. I really like the stacked geometric shapes used in brutalist and modernist architecture, especially when placed in an environment which also has other, more classically attractive (georgian etc) building styles.
Another reason why I like this style of architecture is the materials used; concrete, glass, brick. None of these materials are concealed and all are overtly man-made. Each is fit for its purpose.
*Now know it's The Imperial Hotel on Russell Square
