“I give Mangiantini Construction our highest recommendation!”

Testimonial

My wife and I worked with John, Jennifer, and Jacqui at Mangiantini Construction over the course of two plus years. The scope of work encompassed primarily new construction for our dream home. However, other projects included with the build, were a septic to sewer conversion, new well construction and building a pump house. I give Mangiantini Construction our highest recommendation! John worked tirelessly to guarantee we were satisfied and showed up every morning at the job site to make sure things were in order. He was incredibly patient with all our questions and concerns. He walked us through the whole process from plans to picking out fixtures. Jennifer and Jacqui were instrumental in helping us with picking out colors, providing us with contacts and vendors that offered only the highest quality products. In addition to the professional side of the project, a close friendship was kindled. The client experience is truly personal and caring. We felt like family throughout the process. If you are considering a remodel or new build I highly suggest you consider using Mangiantini Construction. You won’t find this level of professionalism, quality, and attention to detail anywhere else.

About Project

The Thomason Family’s Home Transformation – From Septic Line and Well Upgrade to Stunning New Build — A Complete Evolution in Sonoma County

When the Thomason family contacted us in 2020, their journey began not with a kitchen remodel or a paint swatch but with something far more foundational: converting their aging septic system to a modern sewer lateral and well upgrade.

They had recently inherited a cherished piece of family property — a 1-acre lot with a 1946 original home, a garage, and a barn. The bones were historic, the land was rich in potential, and the vision. To honor the past while creating something brand new.

Phase One: Infrastructure with Intention
Our collaboration started with a practical need: design and planning for a sewer lateral system and well upgrade. But as we walked the property and listened to the Thomasons’ vision, it became clear that this was just the beginning.

Phase Two: From Legacy Lot to Modern Living
With the sewer project complete, we moved into the next stage — designing a brand-new residence that would be both functional and future-focused. The goal: a modern, open-concept 3-bedroom, 2-bathroom home that complemented the character of the land while delivering all the comforts of contemporary living.

This stage involved:

  • Property Surveys
  • Architectural Design
  • Structural & Soils Engineering
  • CEQA Compliance & Environmental Planning
  • Asbestos Abatement
  • Site Planning and Development
  • The New Home: A Vision Realized

 

Once the design was finalized and all permits were secured through the Sonoma County Planning Department, construction began, and the transformation was remarkable. The new home is an inviting, thoughtfully crafted space where clean lines, open space, and natural light bring warmth and modern elegance to the family’s everyday life.

What once stood as a small, post-war house has become a custom-built residence that celebrates both heritage and growth.

“We started with a utility project and ended up with our dream home. The team guided us through every step — we couldn’t be happier.”
