Hundreds of people marched through Cardiff yesterday in support of the city's Guildford Crescent.
Plans to demolish part of the street, including three businesses, have been put on hold for three months. But the future of independent music venue Gwdihw, the Thai House and Madeira restaurants is still uncertain.
Staff at Thai House have already been sent redundancy letters.
In First Minister's Questions in the Senedd on Tuesday, First Minister Mark Drakeford revealed that Cadw have been asked to consider whether buildings in Guildford Crescent could be listed and are "aware of the urgency".
Save Gwdihw and Guildford Crescent campaigner Daniel Minty says he welcomes the Council's support but is still calling for more reassurance for the businesses.
