Building Up vs. Building Out: Pros and Cons

Adding a room or addition is one of the most cost-effective ways to add both financial and emotional value to your home. In fact, after remodeling, 84% of owners have a greater desire to hang around at home more often! 

One question many homeowners ask before they begin their renovation project is whether you should build up or build out. In other words, should you build up by adding a second story addition, or build out to extend your ground floor?

Let’s sift through the essentials of each option to build your dream home.

Building Up vs. Building Out: The Basics

“Building up” during a home renovation means adding one or more stories to an existing structure. This can be a fantastic way to enlarge your living space without affecting your building's footprint. 

On the other hand, “building out” during a renovation involves extending your home’s ground floor area. 

Overall, building up is less costly than building out. 

This is mostly due to cost factors like pouring a new foundation. Both methods have their merits, but the right choice depends deeply on your personal needs, the characteristics of your property, and long-term planning.

Building Up During A Home Renovation: Pros and Cons 

At first glance, building up can seem like the perfect choice—adding square footage at a lower cost than building out. But let’s take a closer look at the pros and cons of building up.

PRO: Potentially Lower Foundation Costs

When you build up, you typically use the existing foundation to support your new room addition. 

This means you can often avoid the costly process of laying a new foundation, which is necessary for building out. Utilizing the existing structure not only saves on costs but also speeds up the construction process.

PRO: Preserves Yard Space

For homeowners who cherish their garden or outdoor living spaces, building up is an excellent solution. This approach allows you to maintain your existing landscape and outdoor areas untouched, as you won't need to sacrifice garden space for the sake of expansion.

CON: Structural Challenges 

Building upwards requires the existing structure to support the weight of additional stories, which can pose significant engineering challenges. 

This often means reinforcing the current foundation and structure, which can add to the complexity and cost of the project. It's crucial to have a structural engineer assess the viability of adding more floors to ensure the safety and stability of the building.

CON: Zoning and Height Restrictions 

Many localities enforce zoning laws that restrict the height of residential buildings. These regulations can limit your ability to add stories to your home, which could impact your plans for building up. 

Before proceeding, it’s essential to check with your local planning department to understand any height limitations or other regulatory restrictions that might affect your project.

Building Out During A Home Renovation: Pros and Cons 

Maybe building up isn’t looking like the right decision given your needs. Building out has a number of pros (and a few cons). Let’s get into it!

PRO: Easier Construction Access

Expanding your home outward often allows for more straightforward construction access. 

Workers can approach the site more easily, and materials can be handled and stored with less disruption to your daily life. This accessibility can significantly reduce labor costs and shorten the project timeline, making it a cost-effective choice for many homeowners.

PRO: Simpler Engineering

Ground-level expansions generally require less complex engineering compared to adding additional stories. 

Without the need for integrating with the existing structures above, the technical demands are lower, reducing the need for specialized engineering services. This can lead to a smoother and often quicker construction process.

PRO: Enhanced Accessibility and Light

Adding space at ground level can greatly enhance the accessibility of your home, making it an excellent option for those with mobility issues or planning for future accessibility needs. 

These expansions also allow for larger windows and doors, which can flood your new spaces with natural light- and who doesn’t want that?

CON: Requires More Land

One significant drawback of building out is the requirement for additional land. If your current property doesn't have the necessary space, you might need to acquire more land, which can be costly and complicated, especially in urban areas where land is at a premium.

CON: Zoning or Permit Challenges 

Extending outward can bring you closer to property boundaries, which may lead to complications with zoning laws and permits. You may face restrictions on how close you can build to your property line, and neighbors’ rights to light could also come into play. 

Navigating these regulations can require additional time and resources, potentially complicating your expansion plans.

Building Up vs. Building Out Cost Comparison

With the prices of materials and labor continuing to fluctuate, the cost-effectiveness of building up versus building out can vary. However, building up often avoids the significant expense of foundation work that comes with building out. 

This makes it a potentially more cost-effective option in many cases, though the specifics can vary based on your location and the complexity of the project.

Making the Right Choice for Your Home

To make the best decision, assess your needs carefully. Consider how each option impacts your daily life and aligns with your long-term goals. 

Consult with professionals who can offer insights specific to your circumstances and local regulations.

If you're contemplating which direction to take for your expansion in 2024, remember, the question is not just about cost but about the quality of life and future usability of your home.

Building Up vs Building Out: Frequently Asked Questions

Is it cheaper to add a home addition up or out? 

Generally, it is cheaper to add an addition up (building vertically) rather than out (expanding horizontally). Building up typically avoids the substantial costs associated with extending the foundation and doing extensive groundwork.

What is the cheapest way to add square footage to a house?

The cheapest way to add square footage to a house often involves building up rather than out. 

Adding a second story or finishing existing spaces like attics or basements can utilize the existing foundation and structure, avoiding the cost of new foundations and extensive ground preparation. 

This approach saves on construction costs but also preserves outdoor living space, which can be a valuable aspect of the property.

Is it cheaper to build a new house or remodel an old one? 

It is generally cheaper to remodel an old house than to build a new one, especially if the existing structure can be effectively utilized. Remodeling allows you to retain the original framework and foundation, which can significantly reduce material and labor costs.

Additionally, remodeling may also offer tax benefits and savings on property taxes compared to new construction, depending on local regulations.
