Sixty exhibitors from builders and architects to DIY and kitchen stores will be on hand from 11am to 6pm both today and tomorrow.
There's also demos from chefs, planning designers and de-cluttering experts.
WLR Event Manager Róisín Ferris says there's a lot to interest people.
"We have almost 60 exhibitors, but we also have a whole schedule of stage presentations," she says, "we have celebrity guests, Roz Purcell is going to do a cookery demonstration, we have a demo kitchen - Bloom's Gary Graham."
Tickets are available online, or you can pay on the door.
They cost €10 each, or you can get 2 for €15. Children enter for free.
