Brindleton Bay Coastal Duplex is a two-unit residential rental designed to fit right into the seaside neighborhoods of Brindleton Bay. The exterior has a classic coastal look with pale siding, stone accents, pitched roofs, awnings, and matching entrances for each side of the property. There’s also plenty of landscaping around the front, along with separate driveways and parking spaces. The build sits on a compact 20×20 lot, so it’s a great option when you want to add rental housing without taking up one of your larger lots. Each unit comes with one bedroom and two bathrooms and is minimally furnished, leaving plenty of room to decorate for whoever moves in. This duplex would work especially well for single Sims, young adults moving into their first place, siblings who want to live next door to each other, or two friends who want separate homes.
Follow these steps to install Brindleton Bay Coastal Duplex on your Sims 4 game:
