What is a PHIUS-certified architect and why does it matter?

PHIUS (Passive House Institute U.S.) is the most rigorous energy performance standard in residential construction. A PHIUS-certified architect designs homes that use 40–60% less energy than code-built homes by engineering the building envelope from the start. Burkholder Architecture is the only PHIUS-certified firm in Southwest Missouri.

How is Burkholder Architecture different from other architects in Springfield, MO?

Most residential architects design to code minimum. Burkholder Architecture designs to a higher standard — integrating energy modeling, airtight building envelopes, and thermal bridge-free details into every project. We are also a full-service firm covering architectural design, interior architecture, landscape, cost estimating, and construction administration.

What does high-performance home design mean in practical terms?

A high-performance home stays comfortable in extreme temperatures without an overworked HVAC system. It features near-silent interiors, consistently even temperatures room to room, and dramatically lower utility bills. The building envelope itself does the work — not just the mechanical systems.

How much does a custom home architect cost in Springfield, MO?

Architectural fees for a full-service custom home typically range from 8–15% of the total construction cost, depending on project complexity. For a $1M home, that is roughly $80,000–$150,000 — including design, engineering coordination, specification writing, and construction oversight.

Can building a high-performance home help me qualify for incentives, rebates, or tax credits?

Yes. High-performance homes designed by Burkholder Architecture may qualify for the federal 45L Energy Efficient Home Credit under the Inflation Reduction Act, utility rebates through programs like Ameren Missouri's energy efficiency incentives, and equipment-level tax credits for high-efficiency HVAC, heat pumps, windows, and insulation. Because energy modeling is integrated into every project from the start, homes can be designed to hit the specific thresholds that unlock these programs.

How long does the custom home design process take?

For a full custom home, the design phase typically takes 6–9 months from initial consultation through construction documents. Construction administration begins once a general contractor is under contract and continues through project completion.

Do you work on projects outside of Springfield, MO?

Yes. Burkholder Architecture works throughout Southwest Missouri and the greater Ozarks region, including Republic, Nixa, Ozark, Rogersville, and Kimberling City. Projects beyond the immediate service area are evaluated on a project-by-project basis.

What is passive house design?

Passive house design is a building science methodology focused on five principles: superior insulation, thermal-bridge-free construction, high-performance windows, airtight building envelope, and controlled mechanical ventilation. It is a performance framework applicable to any architectural style, producing homes that perform at peak efficiency for decades.

Can Burkholder Architecture help with a remodel or addition?

Yes. Burkholder Architecture offers a Performance Audit for existing homes identifying energy inefficiencies and upgrade opportunities. The firm also takes on additions and full remodels aligned with its high-performance expertise.

Details

It started as a 3,262 square foot lake house. The kind of place that holds good memories and not much else. The family didn't want to leave it. They wanted it to grow up.

What they were really building

Not a bigger house. A forever one.

The brief was to keep what they loved about the original and add room for more of life to happen there. Space for more than one generation. A home that could carry them for decades, on the water they already loved.

The problem with most additions

You can usually spot an addition from the driveway. The rooflines don't agree. The old part and the new part feel like strangers sharing an address. And underneath the cosmetics, an older home is often quietly leaking energy through walls and a shell that were never built for it, so bolting on more square footage just means more to heat, cool, and worry about.

The family had seen that version. They didn't want a patched-together house. They wanted one home.

How we built it

Old and new as a single home. We designed the 2,882 square foot addition to read as part of the house, not an appendage to it. When it's done right, you stop being able to tell where the old house ends. That's the goal.
Bringing an old shell up to standard. A remodel is a chance most people miss: the walls are open, and the home can be made to perform far better than it ever did. The result is an older home that finally feels as good as it looks.
Room to be together, and apart. Multi-generational living only works when the home gives everyone somewhere to land.

What it feels like now

A lake house that used to be a weekend has become a home for every day. The spaces flow. The additions don't announce themselves. And the home holds its comfort in a way the original 3,262 square feet never could.

What Anchor House is really about

Sometimes the right move isn't to start over. It's to take something you love and make it whole. The bones were good. The memories were better. We gave them a home worthy of both, built to hold the next generation as well as it held the last.
