How to Design and Build for Wind, Salt Air, and West Coast Weather
Building a custom home on the West Coast is an opportunity to create something truly special, especially in communities like West Vancouver and the North Shore where the landscape meets the ocean. Coastal sites offer an incredible blend of natural beauty, dramatic slopes, and some of the finest views anywhere in British Columbia. They also present challenges that require thoughtful design and technical experience. The wind, the salt in the air, and the consistent moisture shape almost every decision from the foundation to the final finish.
At Kennedy Construction, we have spent years building and renovating homes in these coastal conditions. We understand how the environment influences long term durability, comfort, and performance. Working with the landscape rather than pushing against it is the key to creating coastal homes that feel strong and timeless. When the design is informed by climate and natural forces, the result is a home that performs consistently and ages beautifully long after construction is complete.

Understanding Coastal Exposure
Coastal exposure is unlike any other environment. Homes face wind patterns that change direction through the seasons, moisture that arrives from multiple sources, and salt air that slowly corrodes exterior materials. Designing for these conditions requires experience with both building science and the practical realities that come from living near the ocean.
Some coastal lots are fully exposed, perched high on cliffs or hillsides. Others sit lower, close to the shoreline where the air carries more salt and the humidity settles on surfaces for longer periods of time. Each site behaves differently. In our work across West Vancouver, we begin every custom build with a close look at how wind, water, and sun interact with the property. That early understanding shapes decisions that affect long term performance, especially when it comes to building envelopes, window selection, exterior materials, and structural engineering.
A home near the water must resist the slow but steady impact of salt. It must shed moisture effectively. It must handle the heavy rains and winds that arrive each year. Most importantly, it must remain comfortable inside regardless of what is happening outside.
Designing a Structure That Works With the Climate
The heart of a strong coastal home begins with structure. The frame, the foundation, the anchoring points, and the way the building meets the land all influence how the home withstands coastal forces. On many slopes in West Vancouver, the wind funnels between natural contours. Homes must be designed to manage uplift, vibration, and lateral pressure. In some areas, rock faces or steep gradients require engineered footings and foundation systems that provide stability without disturbing the natural terrain.
We often collaborate with structural engineers who specialize in coastal environments. This partnership ensures that beams, posts, and load paths support both everyday comfort and long term resilience. Even choices such as window placement, exterior overhangs, and deck designs play a part in how the wind moves around the home. When done well, the home feels anchored and calm even during winter storms.
Material Choices That Stand Up to the Weather
Material selection is one of the most important aspects of coastal construction. Some materials deteriorate quickly near the ocean, while others gain character over time. Our goal at Kennedy Construction is to choose materials that look beautiful and perform well for many years.
Here are three examples of materials that have proven to be reliable along the West Coast
• Natural stone that resists moisture and adds weight and presence to the exterior
• Metal roofing that handles rain effectively and provides long term durability
• Composite or treated wood products that stand up to salt air and humidity
Materials that absorb moisture or degrade quickly are avoided. Strong cladding systems, high quality window frames, and corrosion resistant fasteners all play a role in extending the life of the home. These details are rarely visible in the finished space, but they make the difference between a home that holds its integrity and one that requires constant maintenance.
The Building Envelope and Why It Matters
The building envelope is one of the most important systems in any coastal custom home. It controls airflow, moisture movement, and heat transfer. A strong envelope keeps the home dry, stable, and efficient. Coastal climates demand envelopes that allow the structure to breathe while still protecting it from the elements.
In West Vancouver, rain arrives often and from multiple directions. A proper rain screen creates a safe space for moisture to drain and evaporate before it ever reaches the structural frame. High-quality membranes provide the last barrier of defence. Window installation is done with precision, using layered flashing techniques that prevent leaks and manage the constant pressure created by wind-driven rain.
This level of detail is essential for long-term durability. A home with a strong envelope feels consistent inside. There are no drafts, no cold pockets, and no uneven temperature changes. It is more energy efficient and maintains its value over time.
If you are considering a coastal custom home, the Kennedy Construction team can guide you through every decision from envelope design to material selection. Our experience with local climate conditions helps ensure that your home is built to perform through every season.
Balancing Glass and Performance
One of the beautiful characteristics of coastal homes is the generous use of glass. Large windows take advantage of natural light and frame the surrounding mountains and shoreline. They also create challenges when it comes to heat loss, solar gain, and moisture management.
At Kennedy Construction, we focus on window systems that offer both clarity and performance. Triple glazed units, thermally broken frames, and advanced coatings help reduce heat transfer and maintain indoor comfort. These windows make it possible to enjoy panoramic views without sacrificing efficiency.
The placement of large windows also matters. We often work with architects to orient living spaces toward the most dramatic views while balancing exposure to wind and sun. Overhangs, sun shades, and strategically designed eaves help control glare and keep interior temperatures comfortable throughout the year.
Protecting the Home From Salt Air
Salt air is one of the quietest but most damaging forces in a coastal environment. It settles on surfaces, reacts with metals, and accelerates wear on exterior finishes. The effects may not be visible right away, but they appear over time if the home is not designed to manage them.
Coastal custom homes benefit from an exterior that can be washed by the rain and ventilated by the wind. Smooth surfaces, properly sealed materials, and corrosion resistant hardware all help slow the impact of salt. Many homeowners choose metal roofing or cladding that is treated to resist corrosion. Stainless steel fasteners, hinges, and brackets are essential. Even small components, such as deck screws and window hardware, must be selected with care.
In some cases, we recommend exterior design elements that create subtle breaks in wind patterns or reduce direct salt contact. Each property is different, but the goal is always the same. Protect the home and preserve the beauty of the materials over time.
Creating Outdoor Spaces That Work With the Coast
Outdoor living is a major part of West Coast architecture. Covered decks, patios with views, and outdoor kitchens give families more space to gather and enjoy the climate. However, coastal weather places significant demands on these exterior spaces.
Materials must be chosen for traction, durability, and resistance to moisture. Wood decking is often treated or replaced with composite alternatives. Railings are selected for corrosion resistance and longevity. Even outdoor lighting must be designed to withstand the environment.
The most successful outdoor spaces in coastal homes are those that extend interior comfort. They provide shelter, warmth, and seating areas that feel connected to the main living spaces. These areas become natural gathering places year round, especially when protected from wind and rain.
Mechanical Systems Designed for Coastal Life
Systems inside the home matter just as much as the exterior. Coastal homes benefit from mechanical systems that maintain air quality and control humidity. Heat recovery ventilators supply consistent fresh air while reducing energy loss. Efficient heating and cooling systems help the home stay comfortable even during stormy days.
A well balanced mechanical plan reduces condensation, protects the structure from moisture buildup, and supports healthy living conditions. These systems also help maintain long term performance and prevent issues that might appear in poorly ventilated homes.

Bringing Coastal Homes to Life Through Craftsmanship
The construction of a coastal custom home requires craftsmanship at every stage. The framing must be strong and precise. The details of the envelope must be executed carefully. Exterior finishes must be installed with complete attention to weather protection.
At Kennedy Construction, our tradespeople understand the demands of coastal building. Their experience shows in the quality of the work, the way materials meet, and the long term resilience of the home. Every joint, seal, and surface plays a part in how the home performs against the elements.
A Coastal Home Built to Last
A custom home near the ocean should be more than beautiful. It should be a place that stands strong through wind, rain, and years of exposure to the elements. It should feel calm and comfortable inside even when the weather is intense outside. A well designed coastal home becomes part of the landscape. It respects the environment and uses thoughtful construction to create a long lasting connection between architecture and nature.
