Ethernet everywhere, and more than you think you need, even if you don't terminate every connection. Put in Cat-6, as it's easier to pull, and future proof. Everywhere you think you might need one cable, put 2, need 2, put 4. In fact, 4 strands/room might not be overkill. Where everything comes back to, put a patch panel - you can buy panels with 24 square slots and a bracket to hook it into the wall. I'd put this in…

I'd just use wifi.

Spray foam insulation in attic and basement (cellulose based). Mini-split AC system (multi-zoned Mitsubishi or LG). CAT-6 wired, RJ-45 connections (two in each room). Electrical, instant-on hot water heater (no tank). Graywater system to save on toilet flushes. Double-gang outlet boxes (so you can have 4 outlets, instead of 2). Air-to-Air heat exchanger (they are called many things - it replenishes stale, indoor air…

Do instant-on hot water heaters work well? What are the best brands. I'm in an apartment with a small tank that I would like to replace.

Depends where you are. We had one in Puerto Rico (i.e. warm water coming into the house) and I loved it. Up north it's questionable. And note that when it's on, especially during the winter, it will suck down a lot of amperage - like, 60 amps. If you've only got 100 amp service, like I do, you probably want to go with a gas heater.

Here's what I did when we built our house about 10 years ago:

I ran a bundled cable containing 2 cat5 and 2 coax to each bedroom, the kitchen, my office and the family room. Even with wireless it's nice to be able to put another access point in pretty much any room. I did additional single cat5 runs to various places where I didn't think I'd need all four. Today I'm not sure the coax is still justified, but it has been handy for satellite. Now, I'd at least run several cat6 to each location and just leave it in the wall.

I ran speaker wire everywhere, every room including the garage, outside for the deck, even the laundry room. It's just sitting in the walls/ceiling in most places still, but I add a new "node" occasionally.

For the music nodes, I have a bunch of airport express units in the basement where all the wiring terminates. They're not running in wireless mode, just plugged into a gigabit switch with a single channel amp hanging off each one.

I got several of them refurb here (apple has them refurb too): http://www.cowboom.com/product/160235

These are the little amps (they have various wattages): http://www.amazon.com/gp/product/B001P2VV50

You can spend as much as you want on speakers, but I usually go for the cheap ones since they're generally just for background music anyway. That lets me put in a new node for under $150.

Here are some cheap bics that I have in a couple of rooms: http://www.amazon.com/gp/product/B0008MFIFM

Also:

- take pictures/video of all your open walls so you can find your wire - label all your wiring at both ends

If you're able (and if this applies), put a 2"-3" piece of PVC or other conduit from somewhere in your attic to somewhere in your basement, where you can get to it. You never know when you're going to need to fish cable from high to low or vice versa.

I haven't yet seen a suggestion for sound-dampening blankets/foam. If you live in an urban area, keeping the bedrooms quiet could be a huge pay-off as even minor sleep disruptions (you don't even have to be aware of them, let alone be awoken) measurably affect mental acuity and overall energy levels.

If I had had more time the last time around, I would have build in a 'secret' vault that is controlled by RFID. I have an RFID chip in my hand and I'd be able to open the vault by waving my hand in front of it. You need to think this through if you want to do it, though - devise a way to unlock it mechanically, make sure it doesn't open when the power is off, etc. More mundane things: - induction cooking plates in yo…

Totally air-tight houses can be a danger as well; in my home (which is old and "breathes"), a heater once malfunctioned; when I noticed the malfunction (black accumulant around the vents) and called a technician to come check it out, the technician said that if the house had been air-tight I would likely be either severely hospitalized or dead, so sometimes a little non-air-tightness can be good, especially since it…

That's why you need ventilation! The house itself needs to be airtight, for energy preservation. The heat-recuperating system and natural ventilation takes care of taking out the dirty air. Of course when renovating a house (a renovation will never get it airtight) with antiquated dangerous heating systems that can exhaust fumes when malfunctioning, those need to be removed.

Modern building standards (I don't mean building codes, I mean state of the art in building engineering) says to make houses 100% air tight, but with proper ventilation systems, of course. Opening the windows and doors is not enough! CO levels will get back to 80% of their old levels in 30 minutes after closing them! Modern houses need to be continuously ventilated to achieve the highest levels of living comfort.

A home that can breath is also more comfortable. It keeps moisture in check and helps with stale air transfer.

No it's not! That was thought 30 years ago, but building technology has advanced. Ventilation needs to be controlled. Having cracks and leaking windows is very inefficient in keeping an optimal indoor climate, not to mention very energy inefficient. An airtight, very well insulated house with active ventilation (an indoor climate control system, not to be confused with airco) is the best way to get an optimal indoor living climate all year round.

I wouldn't say induction cooking is a no-brainer, not everybody likes it. I rather cook on a gas stove.

Agreed, I much prefer cooking gas. Dislike induction.

Serious cook, serious equipment, serious mistake with a ceramic high-output cook top. We did it for the simple reason that my spouse is tired of cleaning up the disaster of a stove after cooking for 12. We considered induction for the home with some of our pets being underfoot/on counters while cooking.

Our expensive cook top was tested and branded as copper safe. It is, until water gets between the cook top and the copper pan. Also found that the rapid heat generated by an utterly imprecise dial control system could damage cookware, so I now tend to bring them to temp in two stages.

I would definitely go with gas if the line is already brought into the kitchen and available.

You can obtain Fogor induction cook tops and try them out and take them back if they don't work. Same mechanic as a full scale range. Make sure you do a double oven and if you can afford it, install a micro hood with a real vent outside the house - or your attic goods will smell like bacon in perpetuity.
