Castle Impossible

After removing a marble bathroom that was damaging the beams below, Daphne and Ian reimagine the space into an enchanting castle library. And amid the challenges, a surprise visit from Daphne's father brings a welcome boost of warmth and encouragement.

After a surprise request from Daphne's grandmother to move back to the castle, Daphne and Ian face their biggest challenge yet as they renovate one of the most derelict buildings on the property to meet granny's high expectations - the chateau gatehouse.

Daphne and Ian need to stand out from the crowd to secure wedding bookings, so they turn their tired restrooms into luxury powder rooms. The discovery of a hidden bridge in the forest inspires them to add Renaissance-style murals to the powder room walls.

It's full steam ahead to complete the gatehouse interior after Granny expresses shock at its unfinished state. Daphne and Ian install a castle view mezzanine, find a statement chandelier at Tony's in Normandy, and add special touches for Charlie the cat.

Daphne and Ian create a tea room to help pay for a costly terrace fix. Dick and Angel visit to lend their expertise. Ian designs frescoes for the wall, and Daphne upcycles a dresser, a bar, and a dessert cart. Will their new business venture be a success?

To offset the terrace repair costs, Ian plans to turn the dungeon into a medieval tavern to rent to future clients. His vision includes axe throwing and jousting, while Daphne plans an apothecary corner that's linked to the chateau's history.

With a baby due in a matter of months, Daphne and Ian take on their biggest challenge as they race to transform their historic three-story Dove Tower into a luxury bridal suite, creating the perfect wedding retreat far from the cries of a newborn.

In this dramatic season finale, it's a race to the finish line to complete the Dove Tower. But with costs spiraling and time running out, Daphne and Ian face some tough decisions in order to finish the project before their baby arrives.
