We are in process on this ourselves. I asked this recently on reddit too and got a lot of unique answers. https://www.reddit.com/r/HomeImprovement/comments/3pzmrc/what_technologyfeatures_for_a_new_house_build/ https://www.reddit.com/r/HomeImprovement/comments/3pzmrc/wha... I have so far identified the following: - Central distribution room (have this in my current house and it rocks). - Cat6 (shielded) I am running this for both phone and data, yes costs a little more but should help future proof the house a little. - IP Cameras (inside and out), mostly hidden inside to record key doors for security purposes, nothing creepy. - Television cabling, central distribution room with IR repeaters and no DVR's etc in individual rooms. - Stereo in every room & outside - Towel warmer in the bathrooms (nice to have) - Larger Conduit drops 2-3" in places for running new cables. So far I have laid out separate ones for signal and voltage to make things stay separate. - WiFi of course, with likely a automation hub supporting all the key standards. - Security system wiring. - Temperature sensors across the house to allow me to adjust the A/C (won't happen immediately). - Water sensors, flood detection etc - Soundproofing specific rooms/walls, my office, utility room, kids rooms, garage walls, insulating all walls etc. - Solid core doors everywhere As things have been progressing I have been documenting (and imaging) all the runs for plumbing, electrical etc. I am being anal about where things are at and being able to find them in the future. The electricians will hate me in the end, but I am requiring lines to be labeled in the attic space every time there is a change in direction and at all entry/exit points. I am also requiring they run all electric in a specific pattern, not just thrown about the attic. The A/C guys already found out I am a real ass about that type of stuff. But in the end it is you who has to live with it and fix things or pay for them to be fixed and if you can cut out the hunting it saves tons of labor costs later. So far my estimate on extra costs will be around $10-15k above normal, with a lot of that going for the extra soundproofing materials and labor. I am running all signal cables, cameras and extra conduit so that is helping on costs. I also did some of this in my existing house after it was all put together so I have some benefits of learning from past mistakes.
