Common questions
Understanding the Westhaven 398.
Review the principal size, layout, delivery, and installation considerations before requesting a final quote.
Is the entire 398 square feet usable interior space?
No. The approximate 398-square-foot figure represents the expanded exterior footprint. Framing, wall thickness, partitions, cabinetry, fixtures, and built-in elements reduce the finished usable area.
Does the layout include three separate bedrooms?
The product is presented with a three-bedroom configuration. Bedroom sizes, doors, windows, storage, and circulation should be confirmed in the selected floor plan.
What is included with the kitchen and bathroom?
Included cabinetry, countertops, sinks, bathroom fixtures, plumbing components, electrical components, appliances, finishes, and climate systems depend on the selected configuration and written project scope.
Are larger configurations available?
The product is offered in 20-foot, 30-foot, and 40-foot formats. Floor area, bedroom count, transport dimensions, and layout vary by the selected size.
Can it be used as an ADU or permanent residence?
Suitability depends on the installation location and final specifications. Zoning, foundations, utilities, energy standards, permits, and occupancy requirements vary by jurisdiction.
What is needed for a project quote?
Provide the delivery city and state, intended use, selected size, preferred floor plan, site-access conditions, desired finishes, quantity, unloading requirements, and anticipated timing.
Need a larger layout or multiple units?
Share the intended use, project location, preferred size, quantity, and interior arrangement so the appropriate project scope can be reviewed.
