Lots Road Power Station

London, UK

º£½ÇÊÓƵ delivered the complex engineering and heritage‑sensitive solutions that enabled the transformation of Lots Road Power Station into a modern residential landmark.

From 1902 to 1998 Lots Road Power Station fuelled the London Underground. At the time of its construction, it was dubbed the largest power station ever built. It burned 700 tonnes of coal per day, which allowed District Line trains to make the transition from steam to electric. The station eventually powered most of the London Underground.

A bold new vision has transformed Lots Road Power Station into an expansive, dual‑site residential development. Split by a creek across the boroughs of Hammersmith and Fulham and Kensington and Chelsea, the site provided one million square feet of luxury accommodation. It was the last of the three great power stations along the Thames to be returned to use, following the conversion of Bankside into the Tate Modern and Battersea Power Station into a mixed-use complex.

Lots Road Power Station burned 700 tonnes of coal per day, which allowed District Line trains to make the transition from steam to electric.

The wider development includes Tower West, the tallest residential building in SW10 at 37 stories.

Our experts designed a ‘building within a building’ solution, using the latest digital 3D modelling.

We worked closely with Thames Water to achieve a series of significant build-over agreements, to allow the new structures to be developed over a range of subterranean assets. 

Challenge

Lots Road was decommissioned in 2002, at which point the Tube became fully powered by the National Grid. In 2013, the area was rebranded as Chelsea Waterfront, a riverside development comprising ten buildings. This included Tower West, the tallest residential building in SW10 at 37 storeys, and Powerhouse – the new name for the former power station building. º£½ÇÊÓƵ’s multidisciplinary team was engaged to provide design and advisory input across both the new buildings and the adaptive reuse of the power station itself.

Although Lots Road was not a listed building, it was issued with the first licence of its kind from English Heritage to allow development while preserving its rich history. The façade and several key features of the power station were retained, presenting the challenge of weaving 21st‑century high‑end living spaces into a 120‑year‑old industrial complex.

The strict planning restrictions on the development required innovative structural solutions from the team. The existing structure stood as a testament to more than a century of upgrades, effectively forming a virtual east‑to‑west cross-section of historical steelwork added over the years. Our teams worked on the redevelopment of Lots Road Power Station at the same time as many experts across º£½ÇÊÓƵ were engaged on another significant restoration and regeneration project nearby. This enabled us to transfer many of our learnings to enhance the Lots Road project, particularly in understanding the best approaches to intrusive investigations into existing industrial fabric when assessing a historic structure for reuse.

Solution

The English Heritage licence demanded the retention of various sections and the restoration of the facade, so to marry this with the architect’s vision, our experts designed a ‘building‑within‑a‑building’ solution using the latest digital 3D modelling. Our implementation of this enabled full coordination between the old and the new.

Supporting the new superstructure on the existing site required a holistic approach from our ground and structural engineers. The decision was taken to retain the existing foundations but to excavate a new double basement to balance the additional weight and stresses associated with the building’s new purpose. This new basement exploited the original 1902 features to provide generous car parking spaces for the new residents.

Although the new structure built within the power station was entirely self‑supporting, lateral structural interfaces tied the shell of the old building to the reinforced concrete floors of the new structure, allowing for the required movements. Our facades team also took on a compliance‑monitoring role, supporting facade design and implementation across Powerhouse and four other buildings on the site.

Bespoke solutions had to be developed to accommodate the large‑scale redundant infrastructure on the site, such as the substantial inlet and outlet tunnels that once delivered water from the Thames for cooling processes within the power station. We also worked closely with Thames Water to secure a series of significant build‑over agreements, allowing the new structures to be developed over various subterranean assets. Our water engineering experts developed a flood‑risk management strategy for the site and liaised closely with the Port of London Authority, advising on a range of interventions to enhance the historic river wall and build greater resilience against the future flooding impacts of climate change.

Our bridges team designed a small pedestrian bridge over the creek, connecting the two halves of the site. By maintaining the industrial heritage of the area, the project delivered an embodied‑carbon saving by retaining the existing fabric and reusing it as the façade of the new apartment building. The site’s biodiversity was also enhanced through new landscaping. Full‑height evergreen trees were placed where Lots Road’s turbines once stood, and water features were installed between the vast chimneys, which rose 275 feet above the Thames.

Value

The reimagined power station building stands at the heart of an 8.85‑acre redevelopment, framed by the two new glass residential towers at the mouth of the creek.

Completed in 2024, this repurposed icon of London’s Victorian heritage offers 260 luxury flats and helps restore and revive this historic section of the Thames riverside. Our broad, multidisciplinary team delivered critical input across a range of services, acting as a trusted advisor to the client and working closely with a range of collaborators and architects to realise this major regeneration.

Lots Road Power Station has received positive environmental assessments, with BREEAM ‘Good’ for the commercial areas, and EcoHomes and EPC ratings also achieving ‘Good’.
