Bankside residents are to petition the House of Lords for permission to appeal against the planning go-ahead for the proposed 20-storey building alongside Tate Modern.
The development, originally rejected by Southwark Council, will comprise 65,000 sq.ft consisting of 19 flats, 9 key worker units, a restaurant and office space.
BROAD (Bankside Residents for Appropriate Development) lost its appeal in the High Court earlier this summer.
Meanwhile developers London Town is still discussing a start date for construction.
