How to plan a custom home on this page
Answer a few questions about your lot and home. The designer draws an original Avorino floor plan and 3D model. No price is calculated.
- 01
Tell us about your lot
Give the address, or the city you are looking in, and whether you are knocking down and rebuilding, building on a vacant lot, or still deciding. Avorino helps clients look for land, or knock down and rebuild on the lot they already own.
- 02
Choose the size and the layout
Set the finished square feet, one story or two, and the bedrooms and bathrooms. The floor plan draws a foyer, a kitchen with an island, dining, a great room, a primary suite, laundry and a powder room, and a garage if you choose one.
- 03
Pick the style, the garage and the finish level
Each style has its own roof and materials, and each finish level changes the kitchen, baths and floors on the model. These are a visual reference, not a price.
- 04
Add the extras
Add a pool, an outdoor kitchen, solar or a backyard ADU to see them on the lot. A pool and landscaping are not included in Avorino's custom-home price. Solar and an ADU are shown for planning.
- 05
