In our experience, it comes down to when the designer joins the team. On one of our current renovations, the builder invited us to the first meeting before our clients had even closed on the house. While the sale was in escrow, we walked the rooms together and started shaping what the home could become.

When the architect came on, we designed side by side as the plans took shape. Layout questions were solved on paper, like a window that would have left no room for a queen bed.

By the time framing was finished, the trades had more than 100 pages of specifications in hand. The scope grew to four times its original size, and the build still hasn't paused once waiting on a decision.

This project is a perfect example of why the most successful renovations have an interior designer hired from day.

A kitchen should feel just as good on a Tuesday morning as it does when the house is full. 🤍

This one was designed to handle both — everyday routines, quick meals, people gathering in the kitchen, and all the little moments in between.

Beautiful, functional, and made for real life.

For a primary bathroom, we selected a clay tile mosaic for the floor. It was absolutely gorgeous, and it carried a 16 to 18 week lead time.

Timing like that affects an entire project, so we went to work with the builder and trades. Together, we found a way to phase the installation in that one room so the rest of the house could keep moving. Even with that plan, it would still add a short delay at the finish.

So we brought it back to our clients with the full story: why we chose this tile, how the timing had changed, what the phased plan looked like, and a beautiful alternative that was available sooner.

They kept the original. A few extra weeks, for years of stepping onto that floor every morning.

That’s our role in a build. We do the problem-solving and lay out every option, so you can make the decisions that matter most with confidence.

Powder rooms are one of our favorite places to give a home a little personality. 🤍

This one feels soft, classic, and just interesting enough. The wallcovering brings in movement, the deep green vanity grounds the space, and the warm brass finishes give it that extra polish.

Small room, big moment.

Our founder, Rose Zefferino, came to design through construction. In 2005, she was managing residential builds, and like many builders, she assumed design was the simpler side of the job.

Twenty-one years later, and eight years since she opened Z. Domus Designs, she knows how technical good design really is, and how much it shapes the way a build runs.

"A good interior designer will absolutely speed up a project," Rose says. "It makes everything clearer and easier for everyone involved."

A primary bedroom can be more than a place to sleep. 🤍

This sitting area gives the room another purpose — a spot to slow down, have coffee, read, or simply have a little space at the end of the day.

It makes the bedroom feel more complete without filling it just for the sake of filling it.

The martinis are optional. The advice still stands. 🍸

A beautifully resolved home is not created by loving every sample on its own, matching every room, or asking every detail to be the star.

It comes from understanding the complete composition, where contrast creates interest, where restraint gives the eye somewhere to rest, and when experienced guidance may lead somewhere better than the first instinct.

These are four design truths I believe, with or without a dirty martini.

Swipe through, then tell me: which one are we discussing over the next round?

An entry should give you a feel for the home before you see the rest of it. 🤍

Our client loved cleaner lines and a quieter palette, so we brought in interest through texture and shape instead of more color. The subtle wallcovering gives the backdrop a little movement, while the arched Gabby Home console adds a strong architectural moment without making the space feel busy.

Simple, warm, and just unexpected enough.
