Christina meets a couple who wish for a main floor overhaul that boasts an open concept and a bright, airy vibe in the Season 4 premiere. A dream kitchen will anchor the space and feature a wine bar, statement rattan light fixtures and vaulted ceilings with exposed wood beams while dealing with her own bustling family life. Adding to the season lineup, Christina will help repeat clients give their dated bathrooms a modern upgrade and design a resort-worthy pool for her contractor.
