Create a customization brief that protects the desired outcome while exposing cost, code, procurement, and handoff consequences.
Modular homes can offer meaningful design choices, but every change interacts with module dimensions, structure, transport, factory processes, code, procurement, site completion, and warranty boundaries. Customize from ranked outcomes rather than an unlimited option list.
Translate preferences into performance outcomes
Describe why a change matters: accessibility, daylight, storage, family use, energy performance, future flexibility, maintenance, or appearance. An outcome lets the team propose several workable solutions. A fixed product request made too early may create unnecessary engineering, freight, or site work.
Define each proposed change completely
- Location, dimensions, finish, hardware, performance, and acceptance criteria
- Factory-installed, factory-prepared, shipped loose, or site-installed status
- Structural, energy, fire, accessibility, utility, and permit effects
- Lead time, substitution rule, allowance, tax, freight, and labor
- Drawing, specification, model, and contract documents that must change
- Warranty owner and final inspection responsibility
Choose the best production location
| Approach | Potential advantage | Control question |
|---|---|---|
| Standard factory option | Known process and coordination | Is the exact specification included? |
| Engineered factory change | Integrated before shipment | What revisions and cutoffs apply? |
| Site-installed customization | More local flexibility | Who designs, permits, protects, and warrants it? |
Run a disciplined selections process
- Rank must-have, preferred, and optional outcomes.
- Confirm feasibility before pricing finishes.
- Request written cost and schedule effects.
- Update every controlling document together.
- Freeze decisions by an agreed cutoff.
- Inspect samples, installed work, and closeout records.
Watch for customization drift
- One drawing changes while contract or specification does not
- Owner-supplied item lacks lead time, storage, or warranty owner
- Site contractor prices a change the factory already included
- Late substitution changes dimensions, finish, or system compatibility
Keep a selections and change register
For every selection, retain identifier, location, approved sample, responsible installer, current price status, lead time, substitution authority, required drawing revision, cutoff, approval, and verification evidence. Close the register by room and system before final payment and warranty handoff.
