Land Securities Group Plc.

One of our clients, LandSec, are the clever people behind Girls Can Do It Too, an initiative designed to encourage girls to consider a career in construction. Currently, only 11% of the construction workforce are female, and LandSec are attempting to increase this number by providing education and engagement projects and workshops for girls aged 11-13. Featuring workshops on demolition and tower building, as well as challenging the girls to design a planning project of their own (with a focus on budgeting and environmental considerations), LandSec have proven their dedication to addressing the need for diversity in this very male dominated industry. Ruth assists the project by sharing her fascinating insights into the industry and is even on the project judging panel!

Working in schools we take part in the Urban Plan Educational workshops programme, which has now reached more than 2,500 pupils in 100 schools since its launch. Alongside more than 200 industry volunteers engaged across the country, we provide invaluable industry & careers advice to students while guiding them through their workshops and helping judge their presentations.
