The Sims 4’s February 3 base game update has arrived, and for players who spend more time designing than playing, it’s packed with long-awaited tools that finally let them fine-tune staircases with precision. While the upcoming Royalty & Legacy expansion promises new family dynamics and ballroom features, today’s patch delivers something far more enticing for Build Mode enthusiasts: flared stairs and asymmetrical railings.
Gone are the days of rigid, symmetrical staircases. Players can now add a flare to the top or bottom of any staircase, adjusting the width symmetrically or dragging just one side independently—mirroring the flexibility of roof gables. Railings can also be customized to stop partway down, allowing for partial coverage or one-sided designs. These changes may seem subtle, but for players who treat Build Mode like a sandbox, they unlock entirely new architectural possibilities.
The update also introduces granular family tree labels for in-laws, half-siblings, and step-relatives, along with restrictions on flirting between close relations. Visual tweaks include a new Africana style filter in Create-A-Sim and jewel-tone metallic nail swatches, while the Lost Legacies gameplay event launches as a four-week celebration.
For those waiting for Royalty & Legacy, set to release February 12, the expansion will bring its own Build Mode additions—but today’s patch already delivers features that feel tailor-made for players who’d rather spend hours tweaking staircases than hosting royal balls.
