Technology changes quickly, and that stands true for wiring your home. Over the last several years, we have have seen wiring needs change for custom homes and renovations. The days of a traditional phone jack in every room are out, especially on the Cape Cod, where summer residents don't want or need a permanent home phone line. There are many innovations on the market now that will bring the entire home into the digital age. We have even heard talk of appliances that can communicate over the internet, letting you know when dinner will be ready, or when your laundry is done. However, we feel the future of home entertainment and automation will be wireless.
In the past, we have done extensive home automation systems with full structured wiring. These systems are nice, and can control everything from home theater to HVAC and lighting. However, these systems are extremely expensive, and after a few years, they too become outdated.
Here is an article from ThisOldHouse.com discussing the future of wiring for the home.
