The Project

This Redwood City home gained an entire second story. On Jefferson Ave, New Bay Builders designed, permitted, and built a full second-story addition and home remodel — a new upper level with a primary suite and bathrooms, connected to the main floor by a new staircase, all under a new roof structure.

One in-house design-build team managed the project from first drawings to final walkthrough — architecture, engineering, permits, and construction under a single roof, with a single point of accountability.

What We Did

  • Built a complete second-story addition, crowned with a new roof structure and roofline
  • Installed a new interior staircase linking the main level to the new upper floor
  • Created a new primary suite with a spacious primary bedroom
  • Built new bathrooms, including a double-vanity bath, a vanity with gold fixtures, and a tiled shower
  • Finished a bright upper landing connecting the new rooms
  • Completed the exterior with new siding and drought-smart landscaping

The Result

The result is a transformed two-story home with a cohesive new roofline and a light-filled upper level — a new primary suite, spa-like bathrooms, and comfortable spaces for everyday living, all delivered by a single design-build team from start to finish.
