We are choosing to support Homeless Oxfordshire because they, like many in the construction industry, also build homes, just not with physical bricks and mortar! Through the combination of guidance and the provision of a wide range of different types of accommodation, Homeless Oxfordshire enables people to learn how to manage a tenancy, have improved self-esteem and a more positive self-identity and gain the skills that will allow them to move on. Ultimately living and succeeding with greater independence.

Interested in getting involved too? Why not join the Homeless Oxfordshire book club. By joining, you can help someone to start a new chapter in their life. Reading has many benefits for us all; escaping our reality for a little time improves mental health and well-being. By joining, you can help someone to start a new chapter in their life (and all for less than the price of a coffee and a croissant!)
