Warren Buffett to Offer a New Spin on Modular Construction

A startup owned by Berkshire Hathaway aims to make the construction industry more like car manufacturing.

A startup owned by Warren Buffett’s Berkshire Hathaway Inc. aims to shake up the construction industry by making it more like car manufacturing.

MiTek Inc., a Missouri-based construction-technology company, is launching a new modular building venture with New York City-based architect Danny Forster & Architecture. The company plans to build entire rooms for hotels and apartment buildings in factories, and then send them to a construction site to be stacked on top of each other.

MiTek has more than 6,000 employees and sells building components, construction software and services like engineering. The company said it is investing tens of millions of dollars in the modular venture, and plans to start working on its first projects early next year.

Modular construction isn’t new, but companies have struggled to be profitable. Transporting entire rooms to construction sites can be expensive, and some finished buildings have suffered from leaky facades.

Other efforts to streamline the construction process have also had issues. Katerra Inc., a Silicon Valley-based startup, has been looking to move a bigger part of construction work to factories and become a one-stop shop that cuts out middlemen like plumbers and architects. But it has struggled under this model, and its main backer, SoftBank Group Corp., had to bail it out.

MiTek looks to modernize modular construction by requiring assembly by general contractors. Instead of building entire rooms in a factory and driving them to a construction site on a flatbed truck, MiTek wants to ship kits of manufactured building parts along with instructions.

General contractors would then construct rooms from these parts, which would include a steel cage forming the structural support for the room, in a warehouse or other type of industrial building near the construction site.

Shipping the parts, rather than entire rooms, keeps transportation costs low and allows MiTek to supply the country from its factory in Lebanon, Pa., said Todd Ullom, the company’s vice president of modular building solutions.

That companies continue to invest in modular construction despite the challenges speaks to the business model’s promise, proponents say. Construction is a massive industry, plagued by rising costs and inefficiencies. Anyone who manages to automate it the way Henry Ford once changed car manufacturing stands to make a fortune, some industry observers say.

“How come an entire industry is operating on mid-to-late-20th-century mode when we’re a quarter of the way, almost, into the 21st century?” said Barry LePatner, a New York-based construction attorney. “It drives me crazy.”

MiTek’s approach brings its own challenges. Relying on customers to assemble rooms based on written instructions can be tricky. Many general contractors are resistant to change, which could lead to friction and mistakes.

Mr. Ullom, who worked as a general contractor for more than 30 years, said relying on a single supplier instead of numerous subcontractors reduces risk, and the instructions are simple to follow. He said MiTek would offer on-site training.

MiTek also plans to automate much of its 225,000-square-foot factory, for example by using robotic welders, not unlike how auto makers assemble cars. Architect Danny Forster’s firm has designed what could become the world’s tallest modular hotel, a planned 26-story building for Manhattan. He said other modular-construction companies moved work from building sites into factories but failed to make it faster or more efficient.

“A lot of times it has been bringing the chaos of the construction site and just putting a roof over it,” he said.

Strong family financial planning can help reduce taxes and support younger generations. From intrafamily loans and asset gifts to inheritance disclaimers, strategic cooperation can create meaningful financial benefits—when families have the trust and structure to make it work.

Happy is the family whose members—parents, grandparents and grown children—trust each other enough to cooperate on shared goals, especially financial ones. When that is truly the case, Uncle Sam’s tax rules can help as well.

This matters especially now that mortgage rates are above 7%, and many families are looking for ways to help younger members. If the elders have resources and are confident younger ones can cooperate, a family loan could make homeownership possible while providing the elders with a useful income stream.

Other strategies can actually lower taxes, such as when funding 529 plans or Roth IRAs, or when someone inherits a traditional IRA with required withdrawals larger than they will need.

Here are three strategies useful for functional families.

Intrafamily loans

It is perfectly legal for families to lend money to a relative for a down payment or even a private mortgage.

But it is important not to cut corners, says Ryan McKeown, a CPA with Modern Wealth Enhancement in Minnesota. If the loan is for a down payment, be honest with the mortgage provider and have a formal agreement. The lender owes tax on the interest payments received.

If the loan is for a private mortgage, both sides should have legal representation with a formal written agreement, including payment terms. The lender owes tax on the interest, and the borrower often can deduct it if he or she itemizes.

To avoid IRS trouble, the interest rate shouldn’t be lower than the agency’s Applicable Federal Rate at the time of the loan. Currently that is about 5% for loans longer than nine years; about 4.5% for loans three to nine years; and about 4% for loans three years or less. Currently, traditional mortgage rates are generally above 7%.

In addition, the lender could use the $19,000 annual gift-tax exemption (described below) to forgive some or all of the interest or principal annually. If both lenders and borrowers are married, that is up to $76,000 a year. There is no tax for the borrower on such forgiveness, because it is from a gift.

If you’re going this route, McKeown advises against having a fixed plan to forgive the debt. Instead, do it in one-off letters specifying the amount—and keep careful records. Otherwise the IRS might try to treat the loan as a taxable gift.

Asset gifts

Powerful tax-saving moves for families often use gift-tax provisions. Under current law, anyone can give anyone else up to $19,000 of assets annually, free of gift tax. That means a married couple with three grandchildren could give them a total of $114,000 in 2026.

The gifts can be cash or other assets, like stock. For noncash gifts, the cost basis—which is the starting point for measuring taxable gain after a sale—“carries over” to the recipient. So if someone buys $1,000 of stock and gives it away when it is worth $5,000, the recipient’s cost basis is $1,000. If the recipient later sells the shares for $8,000, the taxable gain is $7,000.

Here’s an example showing how gifts could save a family taxes. Grandma is a widow of modest means, while her child and spouse have prospered. The couple has two children, and they want to contribute $5,000 to a 529 college-savings plan for each—but they need to sell stock to do it. Their tax rate on the sale would be 18.8%, and they would need to sell about $11,000 of stock.

However, Grandma’s federal tax rate on the stock sale is 0%. If the couple gives $10,000 of shares to Grandma, she could sell them, pay no tax, and fund the grandchildren’s 529 plans. This saves about $1,000 of tax.

These moves are legal, and they could be used in other ways, such as to help a young person fund a Roth IRA.

But trust among family members is essential: Under the law, givers can’t put conditions on a gift. Grandma could use her stock proceeds to take a cruise, but she makes 529 contributions instead.

Mark Sellner, a retired tax attorney and CPA living in Sarasota, Fla., uses this strategy. His children sell stock he gives them and fund 529 plans for his grandchildren.

The family’s tax savings aren’t huge, but he likes other benefits. The sales by his children don’t boost his adjusted gross income, which in turn could raise his Medicare Irmaa premiums or his 3.8% surtax on net investment income.

Sellner doesn’t worry about his children using the funds for another purpose.

“There can’t be any strings attached to gifts. Of course, it is up to us to decide whether to make them in the future,” he says.

Two caveats: The “kiddie tax” applies to most children under age 24, and it is levied at the parents’ rate on investment income above $2,700 in 2026. Consider this before making gifts to a young person.

Investors who give away stock also forgo the step-up, an important provision that exempts assets held at death from capital-gains tax.

Sellner knows he’s losing a step-up, but says, “The children could use a little more now. Why should they wait 20 years to get it?”

Disclaimers

A disclaimer is a highly useful strategy in which one heir renounces an inheritance in favor of another heir. Assuming family members cooperate, this can save taxes.

Here’s one example. Dad died and had a large traditional IRA that he left to Mom. She has enough assets and income to cover her expenses, and she lives in a state with a stiff estate tax. The inherited IRA would put her estate over the threshold.

Also surviving are three young-adult children. If Mom disclaims all or part of Dad’s IRA within nine months of his death, that amount could go directly to the children. They will have 10 years to empty the account, and the family as a whole will likely save estate and income taxes.

Disclaimers have many key details, especially regarding beneficiary documents. Although heirs have great freedom in choosing what assets to disclaim, the rules about who gets disclaimed property are rigid. It is best if the original owner names tiers of heirs so that if one disclaims, the next recipient is clear.
