Electrical outlet placement depends on the needs you have in your home. National electric code dictates where they can be or not. Consider having your builder install extra electrical outlets outdoors, in bathrooms or in a study where there is a lot of electronic equipment. Plan for your electric circuit breaker panel to have six or even 10 empty spots for future circuit breakers.
Installing two telephone lines in the same location is an easy project. Use an Underwriters Laboratory cable for the best quality voice and data transfer. A dual outlet allows you to connect both telephone lines in one place.
Home wiring for the future can prepare a house for electronic technology. From one central distribution panel, the electrical wiring should include a UTP CAT 5 cable and RG-6 coaxial cable to each room. This hard wiring is more secure than wireless.
