Why Build with Otto?
One trusted team from design through construction
Traditional construction splits architects, builders, and permit expediters, causing delays, confusion, and costly mistakes. Otto is one integrated team—no finger-pointing.
Start with a model or go fully custom
Our architect-designed models give you a beautiful starting point to customize, or work with us on a fully custom design. Either path uses the same predictable process.
Clear pricing with no surprise costs
No vague estimates or missing details.
You’ll get a full scope of work, transparent pricing, and coordinated drawings up front.
Proven through 75+ projects across LA
Our experience means fewer delays, fewer surprises, and better results.
