Architectural trends have extended to hot outside designs which boast low maintenance but high style. Western Rim’s Marcus Hiles has watched first-hand as the demand rise for open-air spaces that are sustainable and reduce costs has steadily risen. Eco-friendly, conservation-minded choices such as rainwater and graywater harvesting systems and permeable pavement are becoming more common throughout the country. Utilizing a rooftop collection system, rainwater harvesting redirects raid from gutters to storage in a well to be treated and repurposed on-site. Graywater takes prior-used wastewater from the home and recirculates it to rest rooms and non-drinking purposes, lessening the need for fresh water and lowering the amount of sterilization. Another popular idea for environmentally minded construction is permeable paving, a process that actually dates back thousands of years to the point when people first made roads by putting stones in beds over the ground. The practice allows the rain to pass through small openings between four layers of filtration (paving material, gravel, fabric, sand) before becoming absorbed by the earth below. The benefits include lowering runoff-based pollution, controlling the flow of storm water to gutters and drains, refilling local groundwater supplies and providing a skid-resistant surface for sidewalks, patios and driveways; with the many attractive patterns often feature crushed stone, brick, and recycled concrete.
