MILWAUKEE, WI RESIDENTIAL 1200 SF COLLABORATORS - BRYAN RAMIREZ
MODULAR
Situated within Milwaukee’s underutilized urban fabric, MODULAR introduces a high-performance, Net-Zero residential prototype specifically designed for the city’s narrowest lots. Developed in partnership with Habitat for Humanity, the project navigates restricting local zoning codes to deliver a "build-ready" solution that balances rapid assembly with architectural integrity. The design utilizes a rigorous 2-foot planning module to optimize the use of standard B-Public prefabricated components—specifically R-52 wall and R-80 roof panels—minimizing material waste and construction costs. By leveraging the sectional depth required for Net-Zero energy efficiency, MODULAR transforms deep window sills into functional interior niches, reclaiming square footage within the compact 20-foot wide footprint.

MODULAR prioritizes a disciplined assembly logic, utilizing a ledgered mid-floor system to facilitate the seamless, undisrupted installation of prefabricated panels. This structural rigor extends to the mechanical core, where a streamlined galley layout optimizes the efficiency of both plumbing and HVAC runs. Within the living volume, a double-height ceiling expands the perceived footprint, flooding the interior with natural light via high-performance south-facing clerestory windows. The residence is engineered to be Net Zero-ready, featuring an integrated infrastructure that allows for a fluid transition to solar energy.
Magnetized panel model showcasing prefabricated standard-size panels and apertures.
The same design, built using traditional stick construction and insulation, would nearly double the heating load. This translates to an extra $390 per year in operating costs totaling nearly $12,000 over a 30-year mortgage—assuming energy costs do not rise.
With Habitat For Humanity’s affordable mortgage model, the owners benefit from lower long term operational costs.
The home is designed to be Net-Zero Ready with the space necessary for the equipment to achieve 0 EUI.
The home would need a minimum of 18 standard size solar panels, or about 288 SF of roof space.
Equipped with solar, the owners would save over $1,800 in annual electricity costs—assuming energy costs do not rise.
