To celebrate and recognise Garfield Weston's donation, South East Dance will name a section of The Dance Space after the Weston family – The Weston Hub.
The area will be a thriving social space that underpins South East Dance's vision to connect local communities with professional dance artists.
Jamie Watton, CEO/Artistic Director, South East Dance, said:
"This kind and very generous donation will ensure The Dance Space is fitted out to the highest specification, enabling us to provide a range of live and digital performances, projects in the local community and training opportunities for professional artists.
"It will allow us to bring the delights and benefits of dance to an additional 75,000 people each year, building on the 88,000 people who already engage with our work."
To date, South East Dance has raised 95% of the £3.5 million required to create The Dance Space, with funding confirmed from public, private and higher education partners.
The organisation's energies are now focussed on raising the final £173,000 to complete the building to the highest standard.
