Under Construction Band Practice Rooms

Head up to Cathays Terrace and you'll find yourself in one of Cardiff's most genuine music spaces—tucked inside the community centre, Under Construction is where the city's working musicians actually spend their time. This isn't a polished venue trying to look edgy; it's a band practice room that hosts gigs, and that's precisely what makes it brilliant. You're getting sweaty rooms, honest sound systems, and lineups built on real community rather than promoter algorithms. It's the kind of place where you stumble in, don't know the bands, and leave having discovered your new favourite outfit.
