San Fernando is its own 2.4-square-mile city inside the Valley — 1920s bungalows and Spanish cottages near downtown, postwar stuccos toward the edges, and multigenerational households on almost every block. It's also our home turf: Guillen Construction is based right here at the Mission Hills line, so a walkthrough usually happens within days.
San Fernando households are often three generations deep, and our remodels here reflect it: opening cramped 1940s kitchens to feed twelve on Sunday, adding a bathroom so mornings work, converting a den into an in-law suite. Small city, our city — we build around family life here every week.
