How We Do It

Architect-Led Advantage

The architect-led design-build process is a specialized form of design-build, where the entire project is led by the firm's in-house architect. This approach guarantees a high level of customization, enabling clients to collaborate closely with the architect to bring their unique ideas to life. The architect remains deeply involved throughout the project, ensuring the development of comprehensive architectural and structural plans. By incorporating client selections into the construction plans from the very beginning, the process also delivers highly accurate bids, reducing uncertainties and change orders. 

Architecture

Our unique Vacation Style Living design philosophy will make you feel like you're living on vacation all year round with a home that's not only beautiful, but also functional.

Construction

As experienced masterbuilders, we manage and oversee the entire construction process so you don't have to worry about a thing.

 

Real Estate

As a licensed real estate agent, Francisca Alonso can help you find a lot to build your dream home on, sell your current home, or purchase a move-in ready home.

Google Reviews from Real Clients

What Clients Are Saying

  • We love the design. We love the uniqueness of our home. Most new homes only differ by the numbers on the mailbox. You cannot tell one from another. We wanted something unique, something special and I feel that is exactly what we got.

    Rob Custom Home Design-Build Client

  • What could have been an extraordinarily difficult process – essentially building a brand-new home from the inside out – was made easy by Francisca, Tony, and their entire team. Being both the architect and builder, the design and construction flowed seamlessly.

    Veronica Modern Renovation Client

  • From the very beginning, they took their time and expertise to guide us through every stage of the design and construction process, providing a single point of contact that eliminated the usual stress of dealing with multiple parties. Working with Francisca and Tony was nothing short of a delight. 

    Catherine Custom Home Design-Build Client

  • 5 years ago my husband started to look for builders that were building the kind of home we wanted, a vacation home for our daily busy lives with lots of lights, fantastic outdoor spaces and practical living spaces, and we found the perfect architects to help us in that endeavor - AV Architects and Builders.

    Andrea Custom Home Design-Build Client

  • Once we realized we needed to build to get what we wanted we started researching. We met with Francisca at a spec home they built and one of the first things she told us is that they don't build spaces with no purpose. It's funny, because we were at a huge house in Great Falls, but it still full intimate and purposeful.
