More than 34 tonnes of glass has been lifted over a west London hospital in a delicate project to renovate a link bridge at the Grade II-listed site.

St Charles’ Centre for Health and Wellbeing, in Ladbroke Grove, has remained open throughout the two-week project, which was due to be completed on Friday (July 17), and involves 40 individual sheets of glass being lifted into the hospital’s courtyard by crane before being secured in place around the second-floor walkway.

Each pane of glass measures 2m x 4m and was manufactured in Austria.

The site, which is owned by NHS Property Services, dates from 1881 and has a number of architecturally-significant features including a 182ft tower and a number of cast-iron galleries and walkways.

The glass casing provides an innovative way to make a key walkway weatherproof and usable for patients, without interrupting views of the hospital’s celebrated Victorian design.
