Living by the coast offers an unparalleled lifestyle, but it poses some unique challenges for home design. The salt-laden air, high humidity, and potential for severe weather all demand a thoughtful approach to building, and, in particular, selecting the right materials. Thus, prospective coastal homeowners must carefully evaluate several considerations when undertaking a new build, which we explain in this guide. With these factors in mind, you can create a beautiful, safe, and enjoyable seaside residence for decades to come.

Choose Durable, Weather-Resistant Materials

Unequivocally, coastal environments are harsh on building materials. Salt spray accelerates corrosion, high moisture levels can cause wood to rot and warp, and intense sun can fade exterior finishes. For these reasons, material selection is paramount.

When building a home near bodies of water, always opt for materials known for their resilience in marine settings. For instance, wood metal-clad windows protect coastal homes, as the metal exterior shields the wooden frame from moisture and salt.

Other durable options include the following:

  • Fiber Cement Siding: It resists rot, pests, and fire, and it holds paint well, reducing maintenance.
  • Stainless Steel or Galvanized Fasteners: These prevent rust and staining, which can compromise structural integrity.
  • Composite Decking: This material withstands moisture and resists splintering and decay better than traditional wood.

Fortify Against Storms and High Winds

According to the Federal Emergency Management Agency (FEMA), a key component of creating safer communities is designing buildings to be more resilient to natural hazards. Coastal areas are susceptible to hurricanes and other severe storms, so structural reinforcement is a critical design element.

Homes along coastlines must withstand:

  • High winds
  • Driving rain, and
  • Potential flooding

Reinforce your home’s structure by installing impact-resistant windows and doors. These products are engineered to resist breakage from flying debris, a common cause of catastrophic damage during a storm.

Additionally, using hurricane straps and clips to secure the roof to the walls provides essential reinforcement against powerful updrafts.

Elevating the home on piles or stilts is another common practice in flood-prone areas, protecting the main living spaces from storm surges.

Plan for Erosion Control and Protective Landscaping

The land surrounding a coastal home is just as important as the structure itself.

Soil erosion from wind and water can undermine a property’s foundation and reduce its value over time. In addition, effective landscaping can stabilize the soil and protect your investment.

Protect your waterfront property with erosion control measures to mitigate this risk. Planting native, salt-tolerant vegetation with deep root systems is an excellent way to anchor the soil.

Seawalls, bulkheads, and riprap (a layer of large stones) can also serve as effective barriers against wave action and shoreline decay. Integrating these features into your landscape design provides crucial protection and enhances the natural beauty of your property.
