How to Use This Page

Choose the project type closest to what you are considering, review the rough square-foot pricing, then use the example scenarios as a starting point. For a more accurate number, contact Xtreme Builders and we can look at the actual project details.

New Custom Home

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 Heated SF Rough Range
Simple tiny home 600 SF 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.
