Great Homes Happen By Design™

As we have been designing and building our homes in fire hazard areas for years, completing fire rebuilds from last years fire and as we embark on assisting in the rebuild after the latest round of dangerous fires, our team utilize a few basic planning and architectural design decisions to greatly improve the chances that our homes will survive the next wildfires.

Planning, Layout & Design

Site planning: Before basic floor plans come into play the initial planning strategy should be to create a buffer or defensible space of incombustible material around the home location. This buffer zone can be comprised of patios, driveways, or low-growing fire-retardant plants. Special attention should be paid to the potential for extremely dangerous up-slope running fire area. Site layout including driveways and turn-arounds that are wide enough to make it easy for firefighters to bring their heavy equipment in close to your home can also create this buffer.

Roofing

Ignition resistant roofing, like metal roofing, can be the front lines of prevention.

Both metal roofing and torched-down flat roofing provide Class A rating. Special attention should also be paid to the substate classification.

Cladding - Siding

Ember resistant exterior siding materials like cement board and stucco can be both preventative and be incorporated into various architectural styles.

Structure

For extended fire rating think heavy timber.

Metal may provide an early ignition resistance but can also reach an earlier structural failure due to temperature. With the density of the heavy timber structure can provide and insulating property to allow longer structural integrity thus keeping your structural envelope secure for longer time periods.

Overhangs & Undersides

Special attention should be devoted to the design and materials on the underside of overhangs also referred to as soffits. This also applies to the under side of cantilevers, balconies, decks, and underfloor areas. These areas are where the flames will be trapped and temperatures will be the highest. (roof soffits, cantilevered balconies, decks, and underfloor areas) because here is where flames will be trapped and temperatures will be the highest. Provide fire resistant materials, protection enclosures and structural integrity to these locations.

Windows & Doors

Windows are the weakest link in defending your building envelope, but there are several methods to strengthen these areas. Double glazed, insulated and tempered glass each add extra layers of defense. The mot secure options are concealed roll-down or side recessed metal fire doors with automatically fusible link closure. They will protect windows and sliding glass doors even if they are left standing open. Fold-down panels or shutters on sloped rails can also be designed to close and latch automatically. And the glass panels can be wire glass or fire safety glass that can stay intact even though cracked by the heat.

Doors with a metal core faced in your preferred material or solid wood doors are rated higher than hollow core wood doors. Garage doors are typically the largest opening into the home and pose a potential threat. Consider installing a metal panel door with an automatic fusible link closure. Detailed construction ensuring a tight fit to block the wildfire accompanying strong winds from blowing embers under the door is critical.

Outdoor Living

Patio

Decks with paving stones instead of commonly used woods use ipe wood which is naturally resistant to fire. Some composite decking materials are certified Class A rated. Special attention should be devoted to the detailing, design and materials used on the underside of the decks to cover or prevent flame spread

Concrete and paving stone patios can also help create wonder outdoor living areas and also provide the defensible fire buffer zones.

Railings, patios covers and pergolas can also be made of Metal or ipe wood.

Emergency Power

Electrical power can be out for weeks or months during a fire. And California Power companies are now proactively turning off parts of the grid during high fire alert days and areas preventing the strong Santa Anna winds from knocking own lines that may cause fires.

Solar - With our homeowners high demand for solar we provide start to finish solar panel, battery storage, design, installation and coordination.

Emergency Generator - the addition of an emergency generator can help keep you up and running when power lines are down after your has home weathered the fires.

Fire Suppression Systems

Sprinklers: many jurisdictions now require fire suppression systems. But innovations and details help minimize their visibility creating a safe space that is aesthetically pleasing

Water Tank: projects may require water storage tanks for use with fire suppression systems. These are usually site specific and correspond to the jurisdiction and fire safety departments location and pressure for nearest water line.

Fire Hydrant: Remote sites may require the addition of a fire hydrant.
