Home Design

At Allegro Design Co., our team of expert designers excels in the delicate dance of form and function.

Let us guide you through the process of creating your dream home, ensuring every corner resonates with warmth and personal touch.
How it works
- Our first step is to sit with you and capture the vision of your home.
- We then create the preliminary plans and present them to you.
- After revisions are made and plans are finalized, we will begin structural design and planning.
- Once the custom home plans are finalized, you’ll be all set to give these plans to your builder.
Structural Design and Planning
Structural Design and Planning is the process of determining how the house is built and what components are used to build it. Our licensed professionals prioritize longevity, practicality, and affordability, helping ensure that your home can stand strong for years to come. With Allegro, you’re not just building a house; you’re creating a home with a lasting legacy.

Septic Design
While the city sewer system might be miles away, our expertise shines in creating onsite water treatment system (OWST) solutions tailored just for you. At Allegro Design Co., we specialize in designing environmentally harmonious, reliable water treatment systems that blend seamlessly with your land. Trust us to ensure every aspect of your home, including its septic system, reflects the custom and sustainable lifestyle you seek, providing you with peace of mind and comfort in your personal retreat.
Disclaimers
- Different counties will have varying requirements for septic systems
- A soils test is needed prior to designing the OWST, as different soils may dictate the design of the system
- The number of bedrooms in your home plan needs to be decided prior to the design of the OWTS


Soils Testing
Your dream home deserves a foundation as unique and solid as your vision. At Allegro Design Co., our experts are dedicated to ensuring your custom home design is perfectly attuned to the unique characteristics of your land. Our in-depth understanding of home design allows us to proactively tailor your home’s foundation to the beautiful land you love, ensuring it stands strong for generations. Trust us to lay the groundwork for your bespoke residence, where every detail reflects your aspirations and ensures enduring stability and style.
Why would I need this?
- Soils testing is required by most counties in the Rocky Mountain region.
- Soil composition can affect the design of your home, to its foundation, and even its plumbing.
- Without a soils test, you may run into substantial complications in the building process.
