Why ADU. Why Now.
The ADU Window
Is Open.

Florida SB 184, record rents, and a housing shortage have created a generational opportunity for property owners. Here's the data.

SB 184
Florida law now requires ADU permits
As of July 2025, every Florida municipality must permit at least one ADU on any single-family lot. The legal barrier is gone. Subject to local zoning — we verify your specific municipality free.
$2,400
Average 1BR rent — Miami Beach
South Florida rents have risen 40%+ since 2020. Your unused backyard land generates $1,800–2,800/month in illustrative rental income. Actual results vary by location and market.
7 days
Estimated on-site assembly time
Factory-printed panels arrive ready. Our crew assembles on your foundation in an estimated 7–10 days. Timeline subject to site conditions and local inspection approval.

Organic materials used
No wood. No steel studs. No cellulose. 100% mineral construction significantly reduces mold, termite, and rot risk — by structural design, not by treatment.
Higher wildfire loss in wood-frame homes
After January 2025 LA fires, concrete construction demand in WUI zones has surged. Concrete doesn't burn. AEGIS Shell™ adds proactive satellite-triggered suppression system design.
50+
Year structural design lifespan
GFRP rebar eliminates corrosion. No replastering, no termite treatment, no rot remediation — ever. A multi-generational concrete asset on your land.

The whole process from site check to keys was exactly as promised. We're renting at $2,100/month — paid off the down payment in 18 months.

★★★★★
After the LA fires we ordered the AEGIS Shell. The satellite activation system alone is worth every dollar. Neighbors asked how we slept during fire season. Very well.
James & Patricia K.

★★★★★
My parents moved in three months ago. Close enough to help, independent enough to be happy. The concrete construction — they'll probably outlive us both.
