London-based architecture studio HawkinsBrown has added a brick extension to a 19th century warehouse to create an office block at 53 Great Suffolk Street in Southwark, London.

The warehouse, which was built in the 1890s and is believed to have previously been used as both a blacksmiths and a meat factory, has been repurposed as a 3,700-metre-square office space named 53 Great Suffolk Street.
Alongside the Victorian building a brick extension, matching the shape and form of the existing structure, has been built to double the building's floor area. The office that now occupies the enlarged building has been shortlisted in the Business building category of the 2018 Dezeen Awards.

"The challenge was to create a new building which can be read as one whole, striking the right balance between being sympathetic to the existing warehouse and its special qualities but also to create a strong, contemporary and contextual building," said HawkinsBrown.
An addition floor was added to the Victorian structure, with the new building built at to the raised height. Dormers at roof level of both structures mean that the extra floor could be built without increasing the building's overall size.
As very little additional weight could be put on the existing warehouse, HawkinsBrown designed a cantilevered structure so that all the loads of the rooftop addition were placed on the new extension's foundations, reducing the impact on the existing building.
