The Poet's Blue

1861 there was once an influential man who built a stone apartment building in the centre of Helsinki.

2023 there is once a woman who was impressed by its history and location.

The Poet's Blue

The Poet's Blue is interior architect Anne Kosonen's showroom home at Mariankatu 7 in Helsinki.

The building was designed by G.T.P. Chiewitz for merchant Henrik Borgström and his family in 1861. Chiewitz also designed the Ritarihuone (Knight's Room) opposite which was built at the same time. Architecturally, the building is significant as it represents an early example of the renewed stone construction method of the 1800s. It also has historico-cultural value connected to the people who contributed to Finnish culture and society at the time that have lived in the area, such as Finland’s ‘national poet’ JL Runeberg, author Zacharias Topelius and philosopher JV Snellman. Today the building’s central position opposite the Presidential Palace houses apartments and offices including architect and design studios.

The Poet's Blue apartment renovation has been designed by Seven Days Studio, led by interior architect Anne Kosonen. The starting point was to decide how to create a functional private home and public work environment in a historic, partially protected milieu. A simple yet atmospheric lighting design and reflective surfaces harmonize the apartment's old structure with custom made unique furniture without driving away the spirit of history.
