Kew Bridge - Verdo (Ecoworld London)

Offsite SECBE Award 2021 finalist

This entry is to promote the build process undertaken by Ecoworld London at their Kew Bridge Development. Phase 2  known as Verdo is 20,000m2 of apartments created using a masonry and sandwich façade system designed and manufactured by Byldis. The offsite manufacturing processes are extended further than the façade and includes internal walls, stairs and landings and precast floors. All produced utilising BIM to include openings and risers for M+E services, ventilation and building management systems.

The challenge for the project included changing building fire regulations, and using European based contractors. Byldis adapted their processes and materials to create new solutions which are NHBC approved. Byldis systems meet all NHBC performance requirements to provide guarantees to future apartment owners. The approach by Byldis and Ecoworld London reduced the effects of the two events that coincided - Covid-19 pandemic and Brexit.

The highest block (Block I) was running at 6 days per level. This produced a  finished 13 story building in about 4 months. All 3 blocks are to be erected on time as per programme despite Brexit and Covid-19 pandemic occurring in the middle of the build. The elements were delivered complete with aluminium frames and glazing. Byldis also produced, assembled and supplied the internal walls, stairs and landings and the precast floors. The three buildings have 9, 13 and 14 storeys. The project has a total floor surface area of 20,000 square meters.

Building fire regulations in London have changed in recent years. Ecoworld London had to develop new solutions for working methods that comply with regulations and are NHBC approved. Byldis meets all requirements.

The prefab sandwich elements are made up of 3 layers: 

  • Inner layer, load-bearing reinforced concrete structure
  • Insulation layer, adapted to project requirements (fire regulations)
  • Outer sheet delivered to design

The sandwich elements are provided with frames and glazing in the factories. During assembly on the construction site, the vertical and horizontal seams between the elements ensure a wind and watertight facade. Facilities/openings for ventilation, heating/cooling and electricity already install in the factory, as well as constructive facilities for installing a balcony, for example.

Building fire regulations in London have changed in recent years. They have had to develop new solutions for their working method that comply with regulations and are NHBC approved. The building regulations stipulate the European minimum performance level for a building and NHBC is a company that offers a guarantee and security for the future apartment owners. The NHBC organisation also sets requirements at the minimum performance levels. Byldis meets all requirements.

Key facts:

  • Ecoworld London - Verdo project has produced 13 storey apartment block in 4 months, at a rate of a floor in 6 days.
  • Zero waste to landfill (only 113 T wastes removed from site in total) with zero reportable accidents and zero NWR incidents from build of structures.
  • Byldis approach was exemplary - and through their cooperation and approach both Brexit and Covid-19 effects were minimised.

  • Client: Ecoworld London
  • Project Partner: Byldis

About the Offsite Award: 

A number of factors are convening to make offsite construction a more attractive solution than ever before.  It can help address systemic failures including low productivity, low predictability, low margins, adversarial pricing, lack of culture for collaboration, limited R&D and investment in innovation and poor image.
