Home Additions Contractor in Salt Lake County for Existing Homes That Need More Space

Expand an older or established home with design, engineering, and construction decisions coordinated before the build starts.

Home Addition Construction in Salt Lake County

Adding onto a Salt Lake County home can be more complicated than building new. Existing foundations, rooflines, framing, utilities, drainage, and finishes all need to be understood before the addition can feel intentional instead of patched on.

Platypus helps homeowners evaluate the addition as both a design problem and a construction problem. That means looking at how the new space ties into the existing home, what structural upgrades may be needed, and how the work can be sequenced around daily life.

Addition Projects We Can Help Plan

  • Main-floor living space, bedroom, bathroom, and kitchen expansions.
  • Garage additions, attached accessory spaces, and expanded entries.
  • Second-story or structural additions that need engineering input.
  • Additions connected to remodels, ADUs, basement work, or site improvements.

Match the House, Protect the Budget

A good addition should look like it belongs and perform like it was planned from the beginning. Bringing design-build thinking into the early stage helps align the look, structure, budget, and construction path before demolition begins.

FAQ

Home Additions Contractor in Salt Lake County Questions

Can Platypus add onto older homes in Salt Lake County?

Yes. Older homes often need careful review of structure, utilities, rooflines, foundations, and finish transitions before an addition is priced or built.

Can you help determine whether to add out or add up?

Yes. The right direction depends on lot constraints, structure, budget, intended use, and how much disruption the owner can tolerate.

Do additions usually need engineering?

Many additions do, especially when the work affects structure, foundations, rooflines, retaining conditions, or second-story loads.

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."

"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."
