Disentangling the systems opens up new possibilities not only for your floor plan, but also for the maintenance and upgrade of your utilities.

Novel systems have evolved to provide dedicated space for utilities. A utility "chase" might include electrical and communication wiring and even plumbing. Surface raceways allow easy access to wiring -- no more knocking endless holes in walls when it's time to catch up with communication technology. Floor modules or specially-designed ceiling tiles may conceal utilities, too.

Utility systems that are independent of the building's structure -- and sometimes each other -- mean less hassle and expense in future system repairs, replacements and upgrades. Homeowners and technicians access these dedicated spaces in the home as easily as you now reach a burnt-out light bulb.
