Home remodels & additions should do more than add square footage. The right design improves daily function, solves layout issues, and makes your home feel more comfortable, efficient, and cohesive. At Platypus Design and Construction, we provide residential design and engineering services for homeowners in Utah and Idaho who want thoughtful remodel and addition plans that work with the home they already have.

Whether you are planning a whole-home transformation, expanding a kitchen, adding a primary suite, or reworking an outdated floor plan, our team creates designs that support your goals while blending with the existing structure. We focus on practical solutions, structural integrity, and a finished result that feels intentional from the inside out.

Custom Home Remodels & Additions Designed Around the Way You Live

Every home has limitations, but the right plan can turn those limitations into opportunities. Our home remodel and addition design services are centered on how you use your space now and how you want it to serve you in the future. We look at circulation, room relationships, natural light, storage, structural conditions, and overall flow to create a design that feels both functional and natural.

Instead of forcing a disconnected addition or a cosmetic remodel that leaves underlying problems untouched, we develop solutions that improve the full experience of the home. That may mean opening up common areas, improving bedroom and bathroom layouts, creating better indoor-outdoor connections, or designing an expansion that looks like it has always belonged there.

Our Home Remodel Design Services

We provide design and engineering support for a wide range of residential remodeling and home addition projects. Each design is tailored to the existing home, the property, and your priorities.

  • Whole-home remodel design for outdated, inefficient, or poorly functioning homes
  • Room additions including bedrooms, bathrooms, living areas, mudrooms, offices, and flex spaces
  • Home expansions that increase square footage while maintaining architectural continuity
  • Layout reconfiguration to improve flow, usability, openness, and daily convenience
  • Kitchen and living area redesign for better gathering spaces and more efficient use of space
  • Primary suite additions and remodels that improve privacy, comfort, and functionality
  • Structural planning and engineering coordination for wall removal, expansions, and major modifications
  • Exterior integration planning to help the addition match the existing home in form and appearance

Whole-Home Remodel Design

A whole-home remodel is an opportunity to fix long-standing issues and rethink how the house supports your lifestyle. Many older homes have compartmentalized layouts, limited storage, awkward circulation, and underused areas. Our design process helps identify what is working, what is not, and what changes will create the biggest improvement.

We design whole-home remodels that can include floor plan changes, room resizing, repurposing unused spaces, improving sight lines, and modernizing how the home functions. The goal is not simply to update finishes, but to create a home that feels more livable, efficient, and aligned with your needs.

Room Additions and Home Expansions

When your current home no longer fits your needs, an addition can provide the extra space you need without requiring a move. A well-designed home addition should feel seamless, not like an afterthought. We carefully consider roof lines, exterior proportions, structural transitions, interior flow, and how the new space connects to the rest of the house.

Our team designs room additions and home expansions for growing families, changing lifestyles, multigenerational living, home office needs, and improved comfort. From a single-room expansion to a larger addition, we help create plans that improve functionality while preserving the character of your home.

Layout Reconfigurations That Improve Daily Living

Sometimes the best remodel does not involve adding more square footage. Reconfiguring the layout can dramatically improve how a home feels and functions. We help homeowners rethink existing space to eliminate bottlenecks, improve openness, add storage, and create more useful room relationships.

Layout reconfiguration may include opening walls, relocating kitchens or bathrooms, adjusting room sizes, creating better entry sequences, or converting underused areas into spaces that support everyday life. These changes can make a home work better without the cost or site constraints of a large addition.

Why Seamless Integration Matters in Home Additions

One of the biggest concerns with any home addition is whether it will look and feel connected to the original house. A successful addition respects the existing structure while improving it. We design with careful attention to proportion, massing, roof design, transitions, and structural compatibility so the finished plan feels unified rather than pieced together.

Inside the home, that same level of integration matters just as much. Ceiling heights, hallway connections, natural light, views, and material transitions all influence whether the new space feels like a natural extension of the home. Our design approach prioritizes that continuity from the earliest stages of planning.

Engineering Support for Remodels & Additions

Residential remodels and additions often involve more than layout ideas. Structural changes, load paths, foundation considerations, framing modifications, and existing site conditions all play a role in what is possible. As a design and engineering team, we help ensure that your project is planned with both creativity and technical understanding.

This is especially important for projects that involve removing walls, enlarging openings, adding a second story, extending the footprint, or making major changes to the structure. By integrating engineering considerations into the design process, we help reduce surprises and create plans that are practical to build.

Our Design Process for Home Remodels & Additions

Good remodeling design starts with listening. We take the time to understand how your home functions today, what frustrations you want to solve, and what you want the finished space to achieve. From there, we evaluate the existing structure and begin developing a design that balances vision, usability, and feasibility.

  • Discovery and consultation to understand your goals, priorities, and existing home challenges
  • Site and existing condition evaluation to assess constraints, opportunities, and structural considerations
  • Concept development to explore layout options, additions, and spatial improvements
  • Design refinement to align the plan with function, aesthetics, budget direction, and buildability
  • Engineering coordination for structural modifications and major residential changes
  • Construction-ready planning to support a smoother path into the build phase

Designed for Homes in Utah and Idaho

Homes in Utah and Idaho come with a wide range of architectural styles, lot conditions, climates, and local requirements. Our team designs remodels and additions with these regional factors in mind. From snow loads and structural demands to neighborhood context and property constraints, we help homeowners plan improvements that are practical, durable, and tailored to where they live.

Whether your home is older and in need of major updates or newer but lacking the right layout, we bring local design and engineering insight to the project. That helps create solutions that not only look right, but also perform well over time.

What Our Clients Say

Real Projects. Real People.
Real Results.

We let our work — and our clients — speak for us. Here's what homeowners and business owners have to say about working with Platypus Design & Construction.

"I am more than satisfied with the excellent work Platypus Design and Construction recently did for us. After a windstorm blew down a portion of our vinyl fence, he not only repaired the fence but saw what needed to be done to secure it so it would withstand future storms. He performed the work quickly, efficiently, and skillfully. The result was excellent and the cost was reasonable. We also appreciate the clarity and friendliness of all his communications and interactions with us. Overall, he did a superb job, even exceeding our expectations."
Bruce Y. Fence Repair
"McKay and his team have done multiple TI buildout projects for me and my Scenthound locations. They have been great to work with through everything to help me get a mix of great pricing, service, and overall product delivery. They are honest with their work and will ensure they take care of you as their client. Further, being able to use them for both design drawing, engineering, and the project buildout and management has saved me tens of thousands of dollars and weeks of time during my buildouts to have it all done with them in house. Platypus will continue to be my go-to for all my future commercial construction needs."
Spencer S. Commercial Build-Out
"We had an outstanding experience working with McKay Harper and Platypus Construction on a garage addition and a custom pergola over our patio. From the beginning, McKay demonstrated a high level of craftsmanship and attention to detail - he was able to match the existing architecture of our home seamlessly, to the point that the addition looks like it has always been there. It was a unique design challenge, and McKay used thoughtful engineering to create a beautiful freestanding structure that feels both solid and elegant. His pricing was very fair, and we would give McKay and Platypus Construction our highest recommendation and would absolutely work with him again."
