New · Kit-of-parts modular designer · Free
Compose a modular California school campus from a kit of parts.
Click building modules from the palette — classrooms, science / STEAM labs, maker / CTE labs, restrooms, admin, library, multi-purpose room, food service, gymnasium, outdoor learning pavilions, and connectors — to compose a campus. The site canvas auto-arranges your composition. Live rollups update on every placement: gross SF, classroom capacity, modular cost band, and the savings versus equivalent site-built delivery. When you're ready, stream a full AI analysis covering DSA Pre-Checked Plans pathway, program viability, configuration gaps, sustainability strategy for prefab delivery, sequencing, and risk callouts — calibrated to your school level and motivation.
For board and community planning conversation. Not architectural design. All California modular K-12 construction still requires DSA review under the Field Act, CEQA, Title 24 compliance, prevailing wage, and a licensed Architect of Record.

AI analysis
~15 seconds · DSA pathway · cost compare · gaps · sequencing
Planning aid only. This is an AI-generated kit-of-parts planning tool, not architectural design. California modular K-12 construction still requires DSA review under the Field Act (Ed Code §17280+), CEQA, Title 24 compliance, prevailing wage (Labor Code §1771), and a licensed Architect of Record under the California Architects Practice Act. DSA Pre-Checked (PC) Plans pathways exist but still require Inspector of Record and site-specific approvals.
Real California modular cost data
Cost ranges use May 2026 California K-12 modular benchmarks ($400–700/SF factory shell + $200–400/SF site work). Equivalent site-built comparison uses $1,500/SF midpoint.
DSA-aware
The AI analysis identifies DSA Pre-Checked Plans pathways that can save 6–12 months of review, plus Inspector of Record requirements that always apply.
Prop 2 / SFP eligible
2025 SFP per-pupil New Construction grants apply to modular: Elementary $15,485 · Middle $16,494 · High School $19,946. Modular replacement of existing modulars is Modernization-eligible.
When modular is the right move
- Replacing obsolete portables. California districts have thousands of 25–45-year-old portables past their service life. Modular replacement under SFP Modernization rules avoids the schedule and cost of site-built rebuilds.
- Post-disaster rebuild. Modular delivery cuts on-site construction time 40–60% — critical when communities are out of school facilities (the Berry Creek and Paradise rebuilds used modular extensively).
- Capacity expansion. Adding a wing of classrooms to an existing campus without disrupting the school year.
- Tight bond budgets. Typical 25–40% cost savings vs equivalent site-built for the same program.
