Modular Cottage Concept

A modular cottage can look refined and permanent, but local classification and foundation review come first.

Inspirational concept overview

A modular cottage concept for visitors comparing factory-built and site-built paths.

This is an inspirational design concept, not a permit-ready plan. Feasibility depends on parcel, jurisdiction, zoning, utilities, septic/well, fire access, overlays, and local department review.
