A modular housing plant: designing the front end before the line runs

What it is

A company spinning off into volumetric modular homes, designed, built and set from its own factory line in Arizona and aimed at workforce and low-income housing, with a new plant coming online. The company is not named.

It engaged Common Ground for an initial analysis of its business model centered on the plant's front end: how it reads a lead, prices it early and guides a developer to a signed feasibility agreement. A factory is a fixed cost with a line that has to stay fed, and the conditions that keep it fed are set in the first calls and the first number, long before a box is built. The company's chief executive originated most leads through his own network and wanted the front end designed before choosing who would run it.

What Common Ground did

• Instead of a memo built around the hypothetical project in the brief, Fowler ran a real two-story rental community of about 200 units that he had bid before through the plant as if it were live, from the first thin lead to a drafted feasibility agreement, so every recommendation had to survive real plans and a real local trade market.
• Common Ground mapped the front end as a stage-gated pipeline: intake and a first call, a free rough estimate, a paid feasibility package, then a preconstruction handoff, each with an entry test, a named output and a gate decision.
• Every budget was split into common costs, identical no matter who builds the units, and vertical delivery, where stick framing, panel systems and volumetric modular actually compete, so a developer compares methods on the only scope where they differ.
• The estimate ran on Kanopi, LÏEF's estimating engine, as two blind quantity takeoffs reconciled against each other, with its band of plus or minus 15 percent and its exclusions printed on its face. A comparison figure recalled from an earlier project was caught running high by double digits against the original document before the number shipped, and source before memory became a written rule, with never tune an input to hit a target beside it.
• Schedule led every page, because a factory builds units indoors while the site is graded, and at this scale carry, interest and rent not yet collected outweigh a small difference in construction cost.
• Everything deeper than the rough estimate sat behind a fixed-fee feasibility agreement, nonrefundable once work starts, delivered within 21 days and credited 100 percent against a build contract signed within 180 days, so the fee itself tests whether a developer is real.
• Fowler tested the business behind the plant from five seats: plant operations, housing finance, tax and incentives, labor cost and technology, and left leadership with one open question from each.

Results

• The analysis was delivered in one week, with the core package built the day the brief arrived.
• On the worked example the factory path ran about 14 months against 18 to 19 months for the two site-built paths, which is why schedule led every page of the pitch.
• Leadership received a front-end operating document and a pursuit risk register to adopt. Nothing was installed by Common Ground; the work was analysis.
