Underfloor heating, much nicer than radiators, cheaper to run and more wall space :) +1 for ethernet.

Oh, yes absolutely. I wish I had made the decision to tear down the cement leveling and installed floor heating when I has the chance. Gas heating is killing me, and don't even get me started on electrical. That, combined with a coke heater will reduce your heating bill significantly. Also, consider solar water heating panels - those are subsidized by the state in some areas.

Ethernet in the walls is a definite yes of course. A backup electricity generator would be cool if power outages aren't uncommon in your area. Something like a central UPS. Good insulation is key. Double glazed windows, etc. A solar water heater is a good idea if you get a good amount of sunshine. Grey-water recycling is a good idea. You can also reclaim heat from it. http://en.wikipedia.org/wiki/Hot_water_heat_recyc…

A couple of points on generators: make sure you can use it in the dark, while you are panicking (I've heard horror stories about generators that couldn't be switched on in an emergency, because nobody could see, and nobody knew how to work them); and make sure that it can't fill your house with poisonous fumes (or even just CO2).

And yeah, visit a hotel that was stylish in the 90s, and never got updated. Just think about the cringe factor your fancy gadgets will have in 10 years time, when everything is wireless and is controlled by iPhones and Androids.

Put in some proper cable ducts so you don't have to tear up the wall once some new standard is introduced.

Put up some solar thermal panels; they last forever and really do work. Look into geothermal, maybe it's worthwhile where you live. But the biggest money saver will be better insulation. You can save up to 70% of your heating/cooling costs by proper insulation.

I'd definitely put in ethernet. But maybe there's some way you can wire everything through 1" PVC pipes, so it's relatively easy to replace it. For Wireless music you can also using Apple's Airport Express? I don't know how expensive solar panels are where you live, but here they are definitely worth it, especially as they get subsidized by the government. Another good green thing is a big tank which uses all your ov…

The conduit is a good idea. If not everywhere, then from various strategic locations, maybe running up and down to basement or attic.

It's an auspicious week to advocate this because Apple and Intel just released Thunderbolt, formerly known as Light Peak. The initial implementation is all copper, but the protocol is designed for fiberoptic, so within five years we may all be routinely plugging keyboards and monitors in one part of the house into a computer in another part, which in turn is plugged into the storage array in the attic. But only if we pull the cables.

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 your kitchen. That's a no-brainer.

- Ethernet to a few places, but don't fuss about it. The jacks will never be where you need them, anyway. Instead, make sure you have a solid backplane so that you can put wifi repeaters on each floor.

- Floor heating, as mentioned above. No-brainer too.

- For optimal living comfort, thick insulation. 10cm (4") of PUR at the least, preferably 16 (6"). Make the house air tight. Put in a ventilation system, preferable with active intake and exhaust, with heat recuperation (it's called 'System D' here, don't know if that's international).

Also, put in an easter egg for the next person remodeling the house. Write a message on an inner wall that you drywall over, put a waterproof sealed envelope with some pictures of you and your family in a false ceiling, those type of things. It's awesome to discover one of those (I once did).

That's what I had in the back of my mind indeed :)

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