Building Should Be Exciting
— Not Exhausting.

You started this project with a vision. But somewhere between the third contractor bid and the second design revision, excitement turned into frustration. Does it really have to be this hard?

Too Many Teams, Zero Alignment

Your designer, engineer, and contractor have never met — and somehow you're the one playing middleman. When they don't communicate, details slip through the cracks and costly rework follows.

Budgets That Spiral

Gorgeous designs that can't be built affordably. "Unforeseen conditions" someone should have caught. When design and construction aren't aligned, your budget pays the price.

Radio Silence

Calls to voicemail. Weeks without an update. Problems you discover long after they started. You shouldn't have to chase your own contractor for answers.

What if your designer, engineer, and builder were all on the same team?

The Cost of Waiting

These Problems Don't Stay Small

Every week with disconnected teams, your project bleeds money, time, and momentum. What starts as a small miscommunication becomes a full-blown crisis — and you're the one paying for it.

It starts small

A "Minor" Miscommunication

Your designer draws something your contractor can't build efficiently. Nobody catches it because they never talk to each other. You don't even know there's a problem yet.

Then it snowballs

Weeks Turn Into Months of Delays

Redesigns. Re-engineering. New permits. Each fix triggers another round of coordination between teams that aren't aligned — and your timeline keeps stretching while carrying costs pile up.

Now it's expensive

Rework, Change Orders & Budget Blowouts

What was quoted at one price is now thousands more. Framing gets torn out. Concrete gets repoured. You're writing checks for work that should have been done right the first time.

The real cost

A Project You Dread Instead of Love

The excitement you had on day one is gone. Now it's stress, finger-pointing, and wondering if it will ever feel finished. This was supposed to be your dream — not a nightmare.

The industry data tells the same story
63% of construction projects exceed their original budget
70% of rework is caused by design errors and poor coordination
2–4× more expensive to fix a problem on-site than in the design phase

You don't have a construction problem.
You have a coordination problem.

And it will keep costing you until your designer, engineer, and builder are finally on the same page.

Get a Team That's Already Aligned
The Platypus Difference

One Team. One Vision.
Zero Headaches.

What if your designer, engineer, and builder already worked together every single day? At Platypus, they do. Our integrated design-build team eliminates the chaos — so your project stays on time, on budget, and exciting from start to finish.

One Integrated Team, Total Alignment

No middleman. No finger-pointing. Our designers, engineers, and contractors collaborate under one roof daily — catching issues in the design phase before they ever reach your jobsite.

3+ disconnected teams
One team, one conversation

Budgets That Actually Hold

When the people designing your project are the same ones building it, every line is drawn with cost in mind. We engineer out the surprises so your wallet doesn't take the hit.

Beautiful but unbuildable plans
Designs built for your budget

Communication You Can Count On

Good news or bad — you hear it fast. We believe the sooner everyone has information, the sooner there are options and solutions. No voicemail runaround. Ever.

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."
