Ocean-side ICF home designed to withstand coastal winds
Strong winds roll off Skagit Bay, blasting the homes on picturesque Fidalgo Island about 70 miles north of Seattle, Wash. That’s why the Hendricks family and their contractor chose insulated concrete forms for the 11,000-square-foot home that has a breathtaking view across the water but must stand up to the worst of Mother Nature.
According to the Daily Journal of Commerce, the building professionals at Bell Construction, the general and concrete contractor, knew that winds on the bay are heavy south winds all winter and a strong west wind in the summer. They took into account wind loads, load capacity, window sizing and insulation into the design. The desire for low noise, comfort and durability were all part of the of the decision for ICF.
The project also included a 1,000-square-foot ICF guest house and a 1,900-square-foot ICF shop building. For the exterior finishing a stucco-type product was applied to the ICF system.
Published reports said that concrete that resembles limestone was used for the living room fireplace surround and the kitchen range hood. Using concrete for this application gave the homeowners the look of Old World craftsmanship.
Patio areas were built with concrete with a hand-trowel finish on a pan deck-type form. This allowed the area underneath to be used for storage as well as for spa mechanical equipment.
Closed-cell spray foam insulatino was applied to the ceilings and then drywall was applied for a fine interior finish. The 12-person spa was lifted by crane onto a reinforced footing and then backfilled with controlled density fill. The concrete slab then caps over the rim of the spa with a pool-type edge detail.
The landscaping and driveway were major focuses for the project. A 200-foot-long concrete wall was placed along the property line to allow for the site to be leveled off. The lower parking area has a black slate stamp border with a colored broom finish body.
The main drive down to the house is a 22-foot-wide natural broom finish with mono-poured curbs. The home also has a half-basketball court finished in concrete.
The guest house has a patio at grade with a fire pit in the center, with a colored concrete with a sand finish.
The home also has a gun safe that is ICF-constructed with reinforced slab footings, ICF walls, concrete ceilings and a 3-by-7-foot safe door. The property also has a 14,000-gallon underground concrete water storage vault that provides groundwater and rainwater collection for irrigation.
