Keltan House is a four storey office building dating from the 1960s located on a prominent cornerĀ  at the junction of Mare Street and Westgate Street in Hackney. The building was previously used by Hackney Council as offices and public facing services.

Our proposals for client, Barworks, centre on the ground floor where existing cellular offices are being replaced by an 850mĀ² open space with a servery, seating and tables that alternate between touchdown spaces, meeting and reprographic areas by day to a more conventional restaurant in the evening. Other smaller retail concessions responding to the locale have been incorporated including a florist, record shop and coffee roastery.

Externally, new openings are formed to allow for large areas of glazing and new entrances to the corners of the building.

The project opened in March 2018 as Mare Street Market.
