About Truoba Mini 425
Designed as an Accessory Dwelling Unit or guest house, this small residence is meant to complement the main home on your property. Its architectural identity is expressed through a strong, uninterrupted connection between indoor and outdoor environments.
The kitchen and great room form a single, open-concept space, a layout commonly found in compact home designs. The living area opens onto a covered porch, which can be screened if desired. Two bedrooms are set apart from the main living area to ensure privacy and tranquility. The bathroom is conveniently located nearby. There are two separate closets: one accommodates a stackable washer and dryer, and the other provides storage space and houses the water heater.

- Reversed Plan +$150
- Plot Plan +$100 Some counties require a plot plan to obtain a building permit. The plot plan shows where the house will be located on the property so the builder knows where to pour foundations. Buyer must provide plot topography or boundary dimensions with stated setbacks.
Truoba's construction drawings must be reviewed by a local structural engineer because soil, snow, wind, and seismic load requirements vary by county. After review, Truoba updates the drawings for free and reissues the set, ready for your permit office.
