What are the typical cost considerations for building a modern 1 story house plan?

The cost to build a modern 1 story house plan can vary widely depending on the home’s size, style, and features. Local building rates and the level of finishes you choose also play a big role.

Key cost considerations include:

• Location: Building costs are often higher in coastal or high-cost-of-living areas. You may also need to account for engineering or permitting requirements based on local regulations.

• Land costs: A single-story home often requires a larger lot than one with two stories, because you can’t build up, so you have to build out.

• Materials and finishes: Your choice of materials can significantly influence the budget.

• Size of the plan: Larger home designs generally cost more to build, though they may have a lower cost per square foot compared to smaller homes.

• Labor and construction: Labor rates vary by region, and complex builds or custom details can increase the overall cost.

How do costs differ between building a modern 1 story home and a modern 2 story home?

The costs to build a modern 1 story home and a modern 2 story home mainly depend on their size, location, and the materials used. Bigger homes cost more because they need more materials and work. Where you build makes a big difference, too – labor and land costs tend to run higher in urban areas than in rural locations. The quality of finishes, like flooring and cabinets, also makes a big difference.

Keep in mind that a two-story home, especially a large one, may be more efficient on a cost-per-square-foot basis. That’s because it can often fit on a smaller lot.
