Europe's 'largest green wall' completes on Warwick car park

  • 1 Comment

One World Design has completed this car park - clad with ‘Europe’s largest green wall’ - for the National Grid’s HQ in Warwick

The 446-space split-level car park boasts a 1,027m² living wall, home to more than 97,000 plants.

The car park was constructed from pre-fabricated steel frame units and built in just six weeks.

The architect’s view

National Grid House, on the outskirts of Warwick and within view of the historic castle, houses some 2,800 staff. It is operational 24 hours a day, every day of the year and is a site which controls and is critical to the power distribution infrastructure in the UK.  National Grids’ commitment to sustainability in all their undertakings has meant that the brief for a new car park on this site would always lead to something extraordinary – with the car park now finished it has literally come alive.

The plant species have been selected to include predominantly Native and Wildlife friendly species, the majority of which are evergreen to provide coverage all year round. The planting of the green wall incorporates Mentha which is a Mint; and this acts as a deterrent for wasps. There are also plants that attract butterflies, such as Hebe pinguifolia “Pagei”, others that provide nectar for Bees (Vinca minor “Bowles Purple”) and others that provide good nesting properties and habitual protection for birds in Winter and Early Spring such as Buxus sempervirens.

‘The living wall is designed to add both to the ecology and biodiversity of the area but also it will flower and bloom adding colour and variety with the seasons. Fruit bearing plants are included – strawberries for instance.

  • one world design architects ethos and moto is ‘design that adds value’ – some mistake this as a purely financial endeavour. Not at all. From the outset one-world design architects has been focused on adding ecological, social and environmental value as a priority. This project, along with the Diamond Jubilee Bridge for instance, is an example of where, with the help of a great forward thinking client and design team, we have succeeded - that is the joy for me in this project
