New London Architecture

Millennium Mills


Millennium Mills is an iconic industrial former flour mill that sits as the centrepiece to the Royal Docks. It is due to be fully restored to create 225,000 sq.ft of flexible workspace.

Millennium Mills is an iconic industrial former flour mill that sits proud and civic as the centrepiece to the Royal Docks. The Mill is now due to be fully restored as part of The Silvertown Development brought forward by The Silvertown Partnership, which will create over 6,000 new homes, 1.8 million sq.ft of next generation workplace, and a new space for cultural and community events.

Millennium Mills was originally built in 1905 but suffered extensive damage during World War One. It was rebuilt in 1933 & 1954 by Spillers and served London until 1981 where it fell derelict due to the decline of shipping trade.

The Millennium Mills refurbishment presents a full circular economy story that conserves the life of existing built fabric by ensuring longevity, adaptability, and reusability as part of a new chapter. The proposal plans to retain and refurbish the original mill building, adapting the industrial space to create 225,000 sq.ft of flexible workspace. The façade will be sensitively preserved and celebrated by retaining the iconic Millennium Mills and Spillers signage. The internal load-bearing structure and foundations will be retained, as well as the original mill equipment, which will be repurposed and put back into the building as a key feature to highlight its industrial past.

New interior additions are minimised, promoting material efficiency and economy. The focus has been on specifying high-quality materials that support longer-life and adaptability of the building, as well as the wellbeing and modern lifestyle of occupants.

Embodied carbon is an essential part of the regeneration of The Mills, and the circular approach works to reduce carbon through the whole lifecycle of the building. The Silvertown development, including Millennium Mills, has a zero-carbon district heating system. Extensive studies have been undertaken to investigate the best solutions for facade retention, , floor infills, and construction of the extension.

“With a shared passion and a wealth of expertise, AHMM, Lendlease, and Buro Happold are reimagining Millennium Mills into a dynamic and inspiring hub of innovation and creativity. The team’s collaborative spirit is fuelling this transformation.”
