When a celebrated green skyscraper runs out of money, the contractor wants the land.
On a riverfront parcel in downtown Milwaukee, where concrete, rebar, and dirt sit behind chain-link fencing, the story of a building that was supposed to change American construction is unraveling in real time. In June 2025, Neutral Edison broke ground to fanfare as what developers billed would become the world's tallest mass timber building - a 31-story, 378-unit hybrid tower at 1005 N. Edison St. that was projected to top out at 375 feet by 2027. By September, the cranes had gone quiet. By November, the tower crane had been dismantled and hauled away. And by March 2026, the general contractor had filed suit seeking foreclosure of the site - a legal move that could strip Madison-based developer Neutral of the property entirely and hand it to another buyer.
Milwaukee has staked a significant piece of its identity on mass timber innovation. The city is already home to the Ascent, currently the world's tallest mass timber structure at 25 stories and 284 feet - a record-setter in its own right that helped prove the engineering case for tall wood buildings in North America. Neutral Edison was supposed to surpass it dramatically, rising an additional six stories and 91 feet to claim a global title.
The project was not just about height. Neutral, a Madison-based developer operating under its original name The Neutral Project, positioned The Edison as a landmark in sustainable construction. The firm estimated the use of mass timber would reduce the building's embodied carbon footprint by 54 percent compared to conventional construction, while cutting operational carbon and energy use by 45 percent. The building's structural system relied on a hybrid of glulam columns, cross-laminated timber floors, and cast concrete cores - a configuration that required an alternate fire compliance process, including what the developer described as the world's first successful three-hour fire resistance test on a mass timber assembly.
The project secured $133.3 million in construction financing in January 2025 and broke ground five months later. Engineering firm Thornton Tomasetti - the same team behind the Ascent - was brought in to design the structural system. Chicago-based Hartshorne Plunkard Architecture handled the building design. Fond du Lac-based C.D. Smith Construction Inc. served as general contractor, the same firm that built the Ascent. The project was embedded in a larger riverfront master plan by Vancouver-based Michael Green Architecture, a pioneer of modern timber construction in North America.
Construction began in June 2025. Within three months, it had stopped.
On September 18, 2025, Neutral CEO Nathan Helbach issued a statement announcing that work had been paused. The explanation cited tariffs and inflation. "Recent tariffs and broader inflation have materially increased key input hard costs," Helbach said. "Pausing to value-engineer is a difficult but prudent step to safeguard the long-term success of 1005 N. Edison." The statement characterized the halt as temporary, framing it as a prudent cost-reduction exercise rather than a financial emergency.
The reality was considerably more severe. By October 2025, Milwaukee City Development Commissioner Lafayette Crump disclosed publicly that the project was facing a $25 million funding gap. Initial cost estimates had put the project at $205 million; costs had ballooned to $230 million, primarily driven by material price increases - a figure that made the gap between what was available and what was needed painfully clear. Tariffs on Canadian lumber, which supplies roughly 25 percent of all wood products used in the United States, were a factor. So was a 15 percent tariff on mass timber imported from the European Union that had been imposed under Section 232 of the Trade Expansion Act. Cross-laminated timber costs had already spiked to a 180 percent premium over standard lumber by 2023, and construction material input prices had been rising at an annualized rate exceeding 9.7 percent through early 2025.
Milwaukee Alderman Robert Bauman, whose district encompasses the Edison site, was blunt in his assessment. "We appear to have a situation where they underestimated their costs, they started construction anyway, and they suddenly came to a realization the project was underfunded as designed," Bauman told the Daily Reporter. He added a plainspoken observation that would prove prophetic: "I've worked here for 21 years and it is very unusual for a project to stop once construction has commenced."
The site became, in the words of one publication, a "construction site-turned-ghost town." In November 2025, C.D. Smith began dismantling and removing the tower crane and other equipment - a step that sent an unmistakable signal about the project's near-term prospects.
On March 6, 2026, C.D. Smith Construction filed suit in Milwaukee County Circuit Court against The Edison SPE LLC and The Edison Project LLC, both affiliates of Neutral. The complaint is stark in its characterization of what happened. The Neutral affiliates "ran out of capital" following cost overruns, the suit states. The developer had terminated loan agreements with senior lenders and entered discussions about either restructuring the project or selling it outright. According to C.D. Smith, Neutral had not provided evidence that it could raise the capital needed to complete the project, had not performed any meaningful value engineering to reduce costs, and had not proposed workable solutions to cover what the contractor described as "millions in unpaid costs."
"In other words, Owner has all but abandoned the Project as contemplated and agreed under the relevant agreements," the complaint states.
C.D. Smith is seeking damages of no less than $11.3 million in unpaid construction bills - not including interest, fees, and court costs - and is demanding that a judge issue a foreclosure judgment against the riverfront development site. If granted, C.D. Smith could take ownership of the parcel and sell it to another prospective developer. The lawsuit names eleven additional contractors and vendors as co-defendants, including project architect Hartshorne Plunkard Architecture, in a strategy designed to consolidate all claims with financial stakes in the outcome into a single proceeding.
The $11.3 million claim represents the core of the contractor's exposure, but it is not the only financial claim outstanding. C.D. Smith had previously filed a $10.1 million construction lien against The Edison SPE in November 2025. The Edison site also carries an overdue property tax bill exceeding $43,000, according to city records.
Neutral CEO Nathan Helbach did not respond to requests for comment on the lawsuit.
The collapse of The Edison has cost Neutral far more than the building itself. In July 2024, the Milwaukee Department of City Development had selected the firm as the preferred developer for a proposed $750 million mixed-use redevelopment of the Marcus Performing Arts Center parking structure - a city-owned, 2.45-acre parcel directly adjacent to the Edison site. The proposal was sweeping: up to 750 residential units, 190,000 square feet of office space, 300 hotel rooms, and a final phase that called for a 55-story timber tower that would have been the tallest building in Wisconsin. It would have been part of a master plan by Michael Green Architecture, the same firm involved in The Edison's broader site concept.
Following The Edison's financial unraveling, Milwaukee officials moved in November 2025 to remove Neutral as the preferred developer for the Marcus Center site. DCD Commissioner Lafayette Crump announced that it was "time to move in another direction." The department is now seeking new development proposals for the parcel - and Alderman Bauman, having watched the sequence of events unfold, offered a characteristically direct verdict on the developer's qualifications: "They were totally inept. They had no financial track record. They had no development track record, and they're kaput."
The Edison was, in fact, Neutral's first high-rise. The firm had previously completed Baker's Place, a 13-story, 206-unit apartment building in Madison.
The Edison's collapse is arriving at a consequential moment for mass timber construction. According to WoodWorks data, 2,524 multi-family, commercial, and institutional mass timber projects were in progress or had been built in the United States as of June 2025 - a figure that reflects rapid sector growth driven by sustainability mandates, evolving building codes, and carbon reduction commitments. The Inflation Reduction Act and state-level clean building incentives had accelerated the pipeline further.
But the structural economics of mass timber construction carry risks that The Edison's failure lays bare. Nearly a quarter of all wood products used in the United States are imported from Canada, making mass timber projects disproportionately sensitive to trade policy. Anti-dumping and anti-subsidy tariffs on Canadian lumber have been a source of persistent friction between the two countries for decades, tied to a long-running dispute over softwood harvested from Canadian Crown lands. European cross-laminated timber and glulam, increasingly sourced for ambitious North American projects, face their own tariff exposure. Construction input prices for lumber and wood products had already risen more than 27 percent since 2020 before the latest rounds of tariffs added further pressure.
The Ascent - The Edison's shorter, completed predecessor - demonstrates that tall mass timber is structurally and financially achievable. But The Ascent was developed by New Land Enterprises, a firm with a substantial track record, backed by institutional financing, and built during a period of more favorable material costs. The Edison was attempting to exceed it in height, complexity, and ambition while being delivered by a first-time high-rise developer navigating a brutal cost environment.
Milwaukee Alderman Bauman's forecast for the site's future is measured. He expects that whatever eventually rises at 1005 N. Edison St. will be a significantly scaled-back version of the original vision - a building redesigned to use the existing foundation work while cutting cost and possibly height. The world's tallest mass timber title, meanwhile, will have to wait.
A project that was presented to Milwaukee as a badge of green ambition has become, instead, a case study in the intersection of sustainability idealism and real estate fundamentals. The tariff environment, rising material costs, and a $25 million funding gap were not abstract risks - they were foreseeable pressures that the developer's financing structure was not equipped to absorb.
The legal proceedings now underway will determine who bears the financial losses from a project that broke ground with ceremony and stopped with silence. C.D. Smith's foreclosure demand may ultimately result in the site changing hands, resetting the development clock for a parcel that Milwaukee officials had designated as a catalytic site for the city's downtown future. For the broader mass timber industry, the Edison story is neither a repudiation of the material nor of the concept - but it is a clear-eyed signal that no amount of sustainability ambition is a substitute for adequate capitalization, realistic cost forecasting, and the financial depth to absorb the volatility that…
