We built Lok-N-Blok because wood-frame is the US residential construction method that 94% of homes still use — and it hasn't meaningfully changed in 200 years. Here's the honest side-by-side, including where wood still wins today.
| Dimension | Lok-N-Blok | Wood-frame (stick-built) |
|---|---|---|
| Core material | Concrete composite, interlocking geometry | Dimensional lumber + nails |
| Joint type | Mechanical interlock + anchor + tension | Nailed, often glued |
| Fire behavior | Non-combustible core | Wood feeds fire |
| Termite / mold / rot | Not a food source; not porous under normal exposure | Vulnerable to all three |
| Wind performance | Engineered for HVHZ 250 mph wind loads (assembly per our details) | Typical stick-framed home rated ~110–150 mph depending on code |
| Install labor | 2-person certified crew; 2-day training | Multiple skilled trades (framing, siding, sheathing) |
| Schedule to dried-in | ~3–5 days (2,000 sq ft shell, pilot data) | ~2–4 weeks typical |
| MEP rough-in | Factory-routed channels in blocks | Drill and snake through studs after framing |
| Service life | 150-year resilience thesis under review | ~30–50 years typical |
| End-of-life | Dismantle + reuse blocks | Demolition to landfill |
| Insurance premium | Typically 10–25% lower in hurricane zones (insurer-dependent) | Standard |
| Upfront material cost | Currently competitive / small premium over stick-built | Familiar lumber supply chain; lowest material cost in soft-wood cycles |
| Code / approval ubiquity | Florida approved; ICC-ES in progress | Approved in every US jurisdiction; no review friction |
| Trade familiarity | Growing crew base; 2-day certification required | Every framer on the continent knows it |
| Aesthetic flexibility | Stucco, paint, exposed, or any cladding | Any cladding |
We are deliberately honest about wood-frame's strengths: it has ubiquity, trade familiarity, and a mature supply chain. Those are real. We are betting that the other dimensions — resilience, labor, schedule, lifecycle — compound into a better long-term choice for most new residential construction.
Every US building official has stamped a stick-framed plan. Lok-N-Blok is approved in Florida today and expanding state-by-state — which means some jurisdictions require an engineering review before your permit.
A framing crew doesn't need training. Our 2-day certification is cheap, but it is a step — and a scheduling consideration on your first Lok-N-Blok project.
When lumber prices crash, stick-framed material is cheaper than ours. Over a full market cycle the cost picture reverses — but on any given month, lumber can underprice us.
Non-combustible core, no termites / mold / rot, and a 250 mph wind-rated assembly. The insurance-claims math alone moves hurricane-zone builds.
2-person certified crew replaces framing, sheathing, and siding trades for the exterior envelope. The schedule savings compound into finance cost savings on every project.
150-year resilience thesis under insurance and engineering review vs ~30–50 for stick-framed. End-of-life disassembly + reuse vs landfill demolition.
Factory-routed channels for plumbing + electrical eliminate the wall-cavity drilling that eats MEP rough-in schedules.
