Building a new home? Remodeling? Adding a room? Better look to the future. We mean electrical and plumbing of the future -- not space-age stuff. Plan ahead while you're still in the construction phase, and make electric and plumbing provisions for water and power you might need tomorrow. A 100-amp panel might be fine for today, but as our dependence on electronic goodies grows, a 200-amp panel will handle any foreseeable future needs without expensive rewiring. Wiring can be upgraded from 14-gauge to heavier capacity 12-gauge wire for just a bit more money, and you'll be ready for home offices, home theaters and home whatevers for many years to come. Same goes for plumbing, which is easy to rough in when framing is open. Think you'll finish that attic space someday? Add a wet bar in the den or a spa on the patio? Think about possible future uses, and run power and water lines today to handle the dreams of tomorrow. And that's the On The House tip for today.
