The Project

This Portola Valley home was beautiful, but the master bathroom didn't match the caliber of the house around it — it was simply too small to feel like the private retreat a master suite should be. The homeowner knew exactly what they wanted, and our job as their design-build team was to bring that vision to life, start to finish.

The key move was expanding the bathroom into the adjacent bedroom and building a brand-new custom closet — reworking the footprint to create a true, spacious master suite. With the new space, we placed a sculptural freestanding tub as the centerpiece, relocated the walk-in shower to a glass-enclosed spot that made sense for the new layout, and finished everything in clean, modern quartz. The result is exactly what the homeowner pictured: a bright, spa-like master suite that finally lives up to the home.

A Master Suite Worth the Space

Reworking the Footprint

The best bathrooms aren't just about finishes — they're about space and flow. By borrowing square footage from the adjacent bedroom and rebuilding the closet, we gave the master suite room to breathe. Relocating the shower and centering the freestanding tub meant every element had the space it deserved, rather than being squeezed into an old, tight footprint. It's the same thoughtful planning we bring to room additions and whole-home renovations.

A Clear Vision, Smoothly Delivered

When a homeowner knows exactly what they want, our job is to execute it flawlessly — and having design, permits, and construction all under one roof is what makes that possible. From the Town of Portola Valley approvals to the final walkthrough, this bathroom remodel came together smoothly, on schedule, and exactly as envisioned.
