    Our Company

    Our Core Values at InVita Homes

    What began as a personal journey to build a home that truly served our blended family has become a professional calling. At InVita Homes, we build from that same place of heart — a desire to do right by people, meet them where they are, and guide them with care through a process that too often feels overwhelming, opaque, and one-sided.
    We believe building a home should feel empowering — not confusing, transactional, or exhausting. That’s why our values are not slogans; they’re the framework for every conversation we have and every wall we raise. We lead with transparency, ensuring you understand what you’re paying for and why. We operate with integrity, delivering what we promise, no shortcuts or hidden costs. We listen deeply and design with flexibility, tailoring solutions that reflect your real life, not a cookie-cutter standard. We prioritize communication, offering clarity instead of complexity, and we price with fairness, using a simple percentage-based model that keeps incentives aligned. Above all, we treat your home with the same devotion, respect, and diligence we gave our own — because for us, this work is personal.

    When Kim and I married, we combined our families, now consisting of four children, and soon realized the necessity for additional space. It was our decision to embark on the path of new construction, with the anticipation that we could realize our vision. We engaged in discussions with various local homebuilders, aiming to create a new home tailored to the needs of our expanded family.

    The process of constructing a new home with specific features and within a reasonable budget presented us with unexpected challenges. We discovered that numerous production builders were inclined to capitalize on the relative lack of knowledge of their clients, a situation we, too, found ourselves in.

    We successfully completed our new home within the planned schedule and budget, staying withing the allowances we had set for ourselves. The result was a source of great satisfaction, and we were eager to share our newfound knowledge with anyone contemplating a construction project.

    Frequently asked questions

    Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

    • What kinds of homes does InVita build?

      We specialize in custom single-family homes. That includes ranches, 1.5-story, or 2-story layouts — and everything in between. We work with people at every budget level, offering realistic paths to high-quality, personalized homes. Whether you bring your own plans, need help designing from scratch, or want to adapt one of our in-house models, we’ve got you covered.

    • What does “driven by integrity” really mean at InVita?

      To us, integrity isn’t just a word — it’s the way we build. We treat every home as if it were our own. That means no hidden costs, no surprises, and no pressure. We’ll give you honest answers, realistic timelines, and a process designed to make you feel confident, not confused.

    • Does InVita Homes have any model homes or past projects I can see?

      While we don’t operate large model home centers like some volume builders, we often feature walkthroughs and project photos on our Facebook page. We’re also happy to share more about past projects or client references during your consultation.

    • How is InVita Homes different from production builders?

      Production builders often rely on upsells, vague pricing, and limited design flexibility. At InVita, we’re transparent from the start — offering custom design, clear communication, and a true partnership. Our pricing model is based on a percentage of your actual build cost, not arbitrary markups.

    • What’s included in a standard InVita home?

      InVita’s standard features go well beyond the basics — including granite or quartz countertops, upgraded cabinetry, luxury master bathrooms, 9’–11’ ceilings, and insulated, fully finished garages. We aim to build every home with quality, comfort, and long-term value in mind, while still scaling finishes to meet your budget.

    • What kind of clients does InVita Homes work best with?

      We work best with clients who want to be informed, involved, and empowered — whether it’s their first build or their forever home. Our process is especially supportive for families looking for clarity, control, and honesty throughout their homebuilding journey.

    • Is InVita Homes a local or national company?

      InVita Homes is a locally owned company based in the St. Louis area. We focus on building single-family custom homes in surrounding counties and communities where we can be hands-on throughout the process — from consultation to walk-through.

    • What inspired the creation of InVita Homes?

      InVita Homes was founded by Randy and Kim, a husband-and-wife team after a deeply personal experience navigating the custom homebuilding process as a blended family. Frustrated by a lack of transparency and genuine support from typical builders, the founders learned firsthand how empowering it is to work with someone who actually wants to teach you the process — not take advantage of your inexperience. That’s the model InVita is built on: clarity, fairness, and the kind of service they wished they had.
