MINI UNIT PLANS 250 Sqft to 399 Sqft
The Mini’s are our most popular home sizes right now, and for good reason. They are small enough to fit on smaller inner city lots and their size makes them affordable to a much larger group of people. Don’t let their size fool you, these plans all feel much larger then they appear!
-
SUITE UNIT PLANS 400 Sqft to 649 Sqft
The Suite’s are the plans that started this whole ADU craze for us. They’re great plans for most suburban lots and also work great in some of the larger inner city properties. Our smallest 2 bedroom plan shows up in this group.
-
VILLA UNIT PLANS 650 Sqft to 1,200 Sqft
The Villa’s are our largest plans in the series and they’re great for estate properties, acreage, larger corner lots and cul-de-sac lots with pie shaped configurations. These homes are great as stand alone structures or with an attached garage.
