Guide
What homeowners need to know.
Prefab strengths
Factory production, repeatable models, and clearer product specs can help if the site is compatible.
Custom strengths
Custom plans handle awkward yards, garage conversions, slopes, design constraints, and higher-control finish goals.
The site decides more than marketing does
Crane access, utilities, setbacks, trees, grade, foundation, and city process can make or break either route.
Cost table
Use ranges until scope is real.
| Item | Planning range | Why it moves |
|---|---|---|
| Prefab path | $250k-$500k+ | Total project cost depends on site work and permitting. |
| Custom path | $300k-$600k+ | More flexibility, more design/project management variables. |
| Garage conversion | $120k-$300k+ | Different category; compare separately. |
Mistakes
Avoid these expensive shortcuts.
- Comparing prefab base unit price to custom all-in project price.
- Choosing prefab before checking site access.
- Choosing custom without budget guardrails.
FAQ

Is prefab or custom better?
