Project overview
About this project
This addition extends the back of a single-story home with a vaulted great room. A white shaker kitchen runs along one wall with a patterned tile backsplash, black countertops and stainless appliances, and a wide sliding glass door opens straight onto the lawn.
An exposed beam crosses the vaulted ceiling and wood-look plank flooring runs through the space. A ductless mini-split heats and cools the new rooms.
The bathroom is the statement piece: black-and-white patterned tile covers the shower walls and floor, paired with a wood vanity, matte black fixtures and open black shelves. Outside, the addition was finished in stucco with a gable roof that matches the original house.

Questions & answers
Room additions: common questions
Planning something similar? These are the questions homeowners ask us most. Anything else, just call.
(650) 749-7436Do room additions need a permit?
Yes. Additions change the structure, roof, electrical and often plumbing, so they are permitted and inspected. We prepare and submit the permit package.
Will the addition match my house?
We design the roof line, siding or stucco, windows and interior finishes so the addition reads as part of the original home.
Can I live at home during an addition?
Usually, yes. Most of the work happens outside the existing house until the final tie-in, which we plan with you.
What can an addition include?
Bedrooms, a primary suite, a bathroom, a larger kitchen or family room. Many additions combine a living space with a new bathroom, like this one.
Do you offer free estimates?
Yes. We visit your home, measure, and give you a written estimate before anything starts.
Client reviews
What our clients say on Google
We hired Ohad and his crew for a home addition, and they did a fantastic job. The new area feels like it’s always been part of the house. Great craftsmanship and smooth process.
⭐⭐⭐⭐⭐ We hired Quarts Construction to transform our backyard into a covered outdoor living space, and the entire project was completed in just two weeks from start to finish. The result exceeded our expectations. Our goal was to create a space that would be comfortable even on rainy days while remaining bright, open, and airy. Quarts delivered exactly that. The craftsmanship and attention to detail were outstanding. From Ohad’s initial design recommendations to his hands-on project management throughout the project, everything was handled professionally and efficiently. Every member of the crew worked hard, took pride in their work, and was a pleasure to work with. The finished patio feels like a natural extension of our home and has completely transformed how we use our backyard. We are extremely satisfied with the outcome and would not hesitate to hire Quarts Construction again for future projects. Highly recommended.
Working with Ohad on our full home remodel was an incredible experience. He helped us through every decision and made sure everything turned out exactly how we envisioned. The team was easy to communicate with and super detail-focused. We still can’t believe how beautiful our home looks!
