Custom Tiny Home
Rough planning guide for smaller homes where layout, storage, and efficiency matter.
View Guide
Tiny homes are smaller, but they are not always cheap per square foot. Kitchens, bathrooms, utilities,
roofing, mechanical systems, and site costs still matter. The total may be lower, but the price per square foot
can sometimes be higher than a larger home.
Simple Tiny Home
Smaller footprint, simple layout, practical finishes, and limited porch area.
Tiny Home With Porch
Adds useful outdoor living space while keeping the heated area smaller.
Premium Small Home
Higher finishes, more detail, better storage, and more custom planning.
Example Tiny Home Scenarios
| Scenario |

Rough Range |
| Simple tiny home |

Often varies widely based on site and finish level |
| Tiny home with porch |
800 SF |
Typically affected heavily by porch, kitchen, bath, and utility costs |
| Premium small home |
1,000 SF |
Can price closer to a custom home because of fixed construction costs |

Porches, Decks, Garages, and Carports
Features that can change the feel, function, and rough cost of a home.
View Guide
Porches, decks, garages, and carports are often part of the lifestyle of the home. They may not all be heated
square footage, but they still affect framing, roofing, foundations, concrete, finishes, and overall budget.
Porches and Decks
Outdoor living areas that affect roofline, framing, rails, decking, ceilings, and finishes.
Carports
Covered parking that can be simpler than a garage but still affects concrete, roof, and structure.
Garages
Enclosed parking and storage that usually adds more cost than a carport because of walls, doors, electrical, and finishes.
