If you’ve ever dreamed of owning or building an adobe-style home, you’re not alone. These unique dwellings feature thick walls, deep-set windows, vigas, and parapets that evoke the unique architecture of the American Southwest. While adobe construction thrives in the arid climate of the Southwest, it’s not limited to just one region. You can get the adobe look by building with insulated concrete forms (ICFs) no matter where you live. 

    There are many benefits to building with ICF blocks, including increased durability, disaster resistance, and energy efficiency. Read on to learn more about ICF construction, adobe-style homes, and how to go about building your own.

    What Is a Traditional Adobe Home?

    Adobe-style homes draw inspiration from the indigenous pueblos and Spanish missions in the Southwest. For centuries, homebuilders have valued the adaptable architecture and functionality of these types of homes. 

    Adobe homes are typically made with flat or gently sloping roofs and parapets (low walls protruding above the roofline), giving them their signature look. Traditionally, adobe bricks consist of sun-baked mud, clay, and straw.

    This indigenous architecture suits the Southwest’s punishing heat. Substantial walls readily absorb sunlight during the day, while stored solar energy warms the interior at night. Their deep-set windows provide shade, and the small window openings reduce heat gain, making the adobe design perfect for high temperatures. As an added bonus, adobe homes are inherently fire-resistant, keep pests out, and insulate against noise.

    However, adobe homes aren’t without their pitfalls. Moisture can compromise traditional adobe bricks, and while precipitation is rare in dry climates, exposure to rain can spell disaster for the homes’ walls. This vulnerability allows for further damage from high winds and seismic activity.

    Although adobe homes have their fair share of problems, constructing adobe-style homes using ICF blocks can significantly reduce the disadvantages, making homes stronger, safer, and longer-lasting — find out more below.

    What Is a Modern Adobe (ICF) Construction?

    Modern adobe-style homes, sometimes called Pueblo Revival, often use insulated concrete forms (ICFs) in their construction. ICF blocks retain the traditional benefits of adobe but have greater durability and moisture resistance.

    They can even recreate adobe shapes and decorative elements like rounded edges and vigas, giving their homes a more authentic aesthetic.


    ICF blocks improve on traditional adobe, creating homes that are highly energy efficient as well as disaster, fire, and pest resistant. By building your own, you gain the time-tested benefits of adobe construction along with the strength and safety that ICF blocks provide.

    Contractors can cut and shape ICF blocks to replicate rounded adobe walls. These flowing shapes and thick walls define the adobe aesthetic, and the versatility of the concrete blocks gives you the freedom to experiment with different architectural designs.

    ICFs prevent thermal bridging with uninterrupted core insulation between block forms. Air barriers also curb heat transfer through convection between wall layers. Simply put, ICF blocks help keep your home at a naturally comfortable temperature, helping you save on heating and cooling costs.

    ICF block cores resist moisture far better than adobe bricks, and while adobe disintegrates when wet, ICF blocks maintain integrity even after flooding. However, it’s still important to waterproof your ICF home.

    ICF blocks won’t get moldy, mildewed, or succumb to termites or rot. The anhydrous concrete core resists both moisture and fire, making ICF a more reliable choice than wood or brick.

    ICF walls can withstand winds of up to 200 mph during hurricanes and tornadoes. The bonded block system and steel rebar reinforcement work to prevent wall failure, helping maintain the integrity of your home. ICF blocks also resist wind-driven projectile impacts, and while cracking is unlikely, it’s easy to repair small concrete cracks.

    In addition to providing temperature insulation, ICF blocks buffer interior noise. Their noise insulation characteristics match or exceed those of traditional adobe.

    So, Is ICF Construction a Reliable Adobe Alternative?

    ICF construction adapts well to the adobe aesthetic but with improved structural performance. When using ICF blocks, you sacrifice nothing in terms of adobe’s appearance yet gain sustainability, resilience, and energy savings. Their disaster resistance, in particular, suits homes in tornado alleys and hurricane zones where adobe historically underperforms. 

    Overall, ICF construction is a durable, thermally efficient adobe alternative that may even save you money on utilities in the long run. If you’re considering building a modern adobe home, ICF is a solid choice of building material.

    FAQs About ICF Construction

    What are typical ICF costs?

    ICF installation typically costs around $8 to $24 per square foot, including materials and labor. However, lifecycle savings from its energy efficiency may offset the initial investment over time.

    How long do insulated concrete homes last?

    Properly installed ICF walls can endure for over 100 years. However, this depends on the quality and thickness of the original installation.

    Do ICF blocks require special skills to install?

    ICF installation requires minimal training beyond standard forming and concrete work. However, improperly sealed ICF walls lose efficiency advantages, so it’s best to hire professionals if you don’t have any prior experience.

    How thick are ICF walls?

    ICF walls are typically 4 to 8 inches thick. This thickness ensures adequate insulation levels for energy efficiency and fits the traditional adobe aesthetic.

    Can you stucco ICF walls?

    Yes. ICF walls work well with applied stucco finishes. These finishes help walls blend well with the surrounding adobe exterior. There are plenty of options for ICF exterior finishes, so be sure to browse the available choices before building.
